FIELD OF THE INVENTION
[0001] The invention relates to a method for dyeing hair and its kits. BACKGROUND OF THE INVENTION
[0002] Consumers who wish to dye their hair typically have two options available, namely: use a product or retail kit available for sale or use the services of a professional beauty salon. The latter, while providing a highly desirable dyeing result, is considerably more expensive than the retail option, and is therefore not available to many consumers, particularly those who dye their hair regularly.
[0003] For consumers who have dyed their hair before, the color and condition of the hair are not homogeneous along the entire length. The strands of hair will comprise virgin hair from the root or new growth hair that has not been dyed previously and, conversely, at the tip, hair that has tried one or multiple hair dye treatments. The tip of the hair is usually the most damaged portion of the hair and is characterized by excessive dye deposition or excess bleaching due to previous oxidizing hair dyeing. The intermediate length of the hair is typically a compromise between these two extreme conditions. However, the problem with current retail hair dye products is that they do not take into account the differences in properties between different hair portions. It’s quite challenging, even for experienced home users, to control dye deposition or lightening provided by a retail hair dyeing product, so as not to deposit excess dye on hair or lighten the length and tip of the hair excessively, since the instructions provided in retail hair dye kits are typically inaccurate, they are often not followed, and the results obtained are not comparable with those of a salon stylist. The overall color appearance is typically not as homogeneous as that provided by a salon stylist.
[0004] Therefore, there is a need to provide a simple method, as well as a simple retail kit for dyeing or lightening hair, which gives the user the possibility of obtaining a different hair color or lightening effect on different portions of the hair. , for example, a different color effect on the hair root versus length and tip of the hair to provide a smooth transition from the root to the tip of the hair that has been dyed previously. SUMMARY OF THE INVENTION
[0005] The present invention relates to a method for dyeing hair comprising the steps of: i) providing a first composition for dyeing hair and a second composition for dyeing hair, the pH of the second composition being lower that the pH of the first composition; ii) applying a portion or all of the first composition to the hair; iii) applying a portion or all of the second composition to the hair; iv) optionally, rinse the hair, each of the first and second compositions comprising one or more oxidizing agents and one or more compounds selected from the group consisting of oxidant dye precursor (s), alkalizing agent (s) ) and their mixtures.
[0006] The present invention also relates to a hair dye kit that comprises a first dye composition, a second dye composition, a first developer composition and a second developer composition, each of the dye compositions, the first and second, comprise one or more oxidizing dye precursors and / or one or more alkalizing agents, and each of the developer compositions, the first and the second, comprises one or more oxidizing agents, the pH of the second composition being developer is lower than the pH of the first developer composition.
[0007] Finally, the present invention also relates to a kit for dyeing hair comprising a first dye composition, a first developer composition and a pH reducing agent, the first dye composition comprising one or more precursors of oxidizing dye and / or one or more alkalizing agents and the first developing composition comprises one or more oxidizing agents, and the first dye composition, the first developing composition and the pH reducing agent are packaged separately. DETAILED DESCRIPTION OF THE INVENTION
[0008] Although the specification ends with claims, which particularly point and distinctly claim the invention, it is believed that the present invention will be better understood from the description that follows.
[0009] As used in this document, the term "hair" to be treated may be "alive", that is, in a living body or it may be "non-living", that is, in a wig, braid or other hair aggregation of non-living keratin fibers. Mammalian hair is preferred, preferably human hair. However wool, hides and other keratin-containing fibers are suitable substrates for the compositions according to the present invention. The terms "root", "hair root", "line of hair rooting" and "virgin hair" all refer to hair that has not previously been treated with a composition for dyeing or lightening hair.
[0010] By composition for "hair dyeing" is meant a composition suitable for changing hair color. The composition for hair dyeing may comprise oxidizing dye precursors, direct dyes or even not having, or substantially not having dyes, in the case of whitening only compositions, where the color change is mainly caused by the degradation of the natural melanin contained in the hair of the hair, by the oxidizing agent. The terms "hair dyeing composition" and "hair dyeing method", as used in this document, also cover, respectively, the terms "hair lightening composition" and "hair lightening method".
[0011] In the preferred embodiment, according to the present invention, hair dyeing compositions are applied to hair that has previously been dyed with hair dyeing compositions. In this case, the terms, "root", "hair root", "line of hair rooting" and "virgin hair" all refer to the portion of hair that has grown since the last hair dyeing, said portion being virgin hair, that is, with natural color, and the term "length and tip of hair" refers to the remaining portion of hair that has been dyed previously.
[0012] "Liquid" means liquid at 25 ° C and atmospheric pressure (101 kPa (760 mmHg)).
[0013] "Solid" means solid at 25 ° C and atmospheric pressure (101 kPa (760 mmHg)).
[0014] All percentages are expressed in weight of the total of the composition, except where otherwise specified. All reasons are weight reasons, unless otherwise specified. Hair dyeing method
[0015] The present invention relates to a method for dyeing hair, as set out earlier in this document.
[0016] The first composition for hair dyeing can be applied to the hair root and the second composition for hair dyeing can be applied to the length and tip of the hair.
[0017] Alternatively, the first composition for hair dyeing can be applied to one strand of hair and the second composition for hair dyeing can be applied to another strand of hair.
[0018] The pH difference between the first composition and the second composition can be at least 0.25 or at least 0.5 or at least 1 or at least 2.
[0019] The pH of the first and / or second hair dyeing compositions can be modified by adding a pH reducing agent, respectively to the first and / or the second hair dyeing composition.
[0020] In step iv) of the method, the hair can be rinsed with water and / or shampoo. After rinsing, it can be additionally dried and combed as usual. A conditioning composition can be applied to the hair after rinsing, preferably before drying and styling.
[0021] The present description is not limited to the modalities in which only two different hair dyeing compositions are applied to the hair, the second hair dyeing composition having a lower pH than the first hair dyeing composition. The application of more than two different hair dyeing compositions on the hair can be contemplated, each time the pH of the next composition is lower than the pH of the previous composition. PH reducing agent
[0022] According to the present invention, a pH reducing agent is typically an acid, which is added to a composition to lower the pH of the composition.
[0023] The pH reducing agent can be selected from the group consisting of acetic acid, acetyl mandelic acid, adipic acid, aluminum lactate, aluminum triformate, ammonium lactate, ammonium molybdate, ammonium nitrate, ammonium thiocyanate, vanadate ammonium, ascorbic acid, azelaic acid, babassu acid, bakuhan, benzyl acid, bismuth citrate, boric acid, calcium citrate, calcium dihydrogen phosphate, calcium phosphate, citric acid, diamonium citrate, dioleyl phosphate, pyrophosphate disodium, etidronic acid, fumaric acid, galacturonic acid, glucoheptonic acid, glyuronic acid, glutaric acid, glycine, glycolic acid, glyoxylic acid, hydrobromic acid, hydrochloric acid, hydroxyethylpiperazine ethanesulfonic acid, isobutyric acid, lactic acid, lactobionic acid, glycolic acid , magnesium lactate, maleic acid, malic acid, malonic acid, maltobionic acid, metaphosphoric acid, monosodium citrate, clayite powder, phenolsulfoft aleine, phenyl mercury borate, phosphoric acid, phosphorus pentoxide, potassium bicarbonate, potassium biftalate, potassium and magnesium aspartate, sodium and potassium tartrate, potassium tartrate, propane-tricarboxylic acid, quinic acid, ribonic acid salicylic acid, sebacic acid, sodium aspartate, sodium bisulfate, sodium borate, sodium butoxyethoxy acetate, sodium phosphate calcium and boron, sodium phosphate calcium and copper, sodium phosphate calcium zinc, sodium citrate, sodium glycolate, sodium lactate, sodium phosphate, sodium succinate, succinic acid, sulfuric acid, tartaric acid, taurine, hydroiodide triethanolamine, trisodium sulfosuccinate, triticum vulgare protein, triticum vulgare seed extract, uric acid, zinc hexametaphosphate and mixtures thereof . The pH reducing agent can be selected from the group consisting of citric acid, phosphoric acid, salicylic acid, etidronic acid, acetic acid, ascorbic acid, hydrochloric acid, sulfuric acid and their mixtures.
[0024] The pH reducing agent can be supplied as a solid or a liquid.
[0025] In the modalities in which the pH reducing agent is supplied as a liquid, it can be a solution, an emulsion or a suspension. In these embodiments, the solvent used to form the solution, emulsion or suspension can be water. Alternatively, the solvent can be any solvent with a polarity index of 4.8 or more. The liquid can be encapsulated in a controlled release coating.
[0026] In the modalities in which the pH reducing agent is supplied as a solid, it can be a powder, a precipitate or a crystal. The solid can be encapsulated in a controlled release coating.
[0027] Although not intended to be bound by theory, it is believed that when the pH of a hair dyeing composition that comprises one or more oxidizing dye precursors is reduced, the rate of color-forming reaction in the composition (ie , before application to the hair) may become lower or higher, depending on the nature of the dye precursors. In the modalities in which the rate of color formation reaction in the composition becomes lower due to the reduction of pH, the rate of color formation reaction in the hair may also become lower and therefore the user can apply such a composition in the length and tip of the hair that has already been dyed previously and reduce the risk of excessive deposition of dyes in portions of the hair that have been dyed previously. Alternatively, in the modalities in which the reaction rate of color formation in the composition becomes higher due to the reduction in pH, the increase in the reaction rate may have the consequence that some of the dye precursors may not have the time to diffuse into the hair before the hair dyeing reaction occurs and therefore such a composition reduces the risk of excessive dye deposition when applied to portions of the hair that have been dyed previously.
[0028] Although not intended to be bound by theory, it is believed that when the pH of a hair dyeing composition that does not comprise oxidizing dye precursors is reduced, that is, a composition for lightening hair, the concentration of anions in hydroperoxides that are involved in the hair bleaching process can become lower and therefore the reaction rate of the bleaching process can also become lower and, consequently, the user can apply such a composition on the length and tip hair that has been previously bleached, and the risk of over-bleaching portions of hair that have been previously bleached is reduced.
[0029] Therefore, when carrying out the method according to the present invention, it is possible to provide a different color and / or lightening result in different portions of the hair in a simple way, without the need to use the services of a beauty salon professional.
[0030] Additionally, by carrying out the method according to the present invention, in which the first composition for dyeing hair is applied to one strand of hair, and the second composition for dyeing hair is applied to another strand of hair, it is possible to obtain the color variation from strand to strand.
[0031] The second composition can produce a color in the hair such that the color variation AE00 *, expressed in the CIE L * a * b * system, between the hair dyed with the second composition and the hair dyed with the first composition is greater or equal to 1, measured according to the color variation test method. Although not intended to be bound by theory, it is believed that the existence of such AE00 * color variation helps to ensure that the overall color result obtained with the second composition is significantly different from the overall color result obtained with the first composition.
[0032] The second composition can produce a color in the hair such that the difference in brightness of the color AL * expressed in the CIE L * a * b * system, between the hair dyed with the second composition and the hair dyed with the first composition is greater than 0, measured according to the color variation test method. Although not claiming to be bound by theory, it is believed that the existence of such a difference in luminosity of the color AL * helps to ensure that the second composition provides a lighter color result, when the second composition is applied to the hair, than when the first composition is applied to the hair, for example, on the length and tip of the hair versus the hair root.
[0033] Alternatively, the second composition can produce a color in the hair such that the difference in luminosity of the color AL * expressed in the CIE L * a * b * system, between the hair dyed with the second composition and the hair dyed with the first composition is less than 0, measured according to the color variation test method.
[0034] The pH of each of the hair dyeing compositions, the first and the second, can be from 3 to 11. The pH of the first hair dyeing composition can be from 8 to 11 and the pH of the second composition can be be 3 to 10.
[0035] The method may additionally comprise the steps of: a. mixing a first dye composition with a first developing composition to obtain the first composition, the first dye composition comprising one or more oxidizing dye precursors and / or one or more alkalizing agents and the first developing composition comprising one or more agents oxidants; B. mixing a second dye composition with a second developing composition to obtain a second composition, the second dye composition comprising one or more oxidizing dye precursors and / or one or more alkalizing agents and the second developing composition comprising one or more agents oxidants, the pH of the second developer composition being lower than the pH of the first developer composition.
[0036] Step b) can be carried out between steps ii) and iii).
[0037] The method can additionally comprise the waiting steps for a period of time from 10 min to 40 min, or from 15 min to 30 min, or 20 min, which is carried out between steps ii) and iii ), and waiting for a period of time from 5 min to 20 min, or 10 min, which is done between steps iii) and iv).
[0038] Alternatively, step b) can be performed immediately after step ii) and step iii) can be performed immediately after step b) and the method can additionally comprise the waiting step for a period of 5 min at 40 min, or from 20 min to 40 min, or 30 min, which is performed between steps iii) and iv).
[0039] The first and second dye compositions may comprise the same or different oxidant dye precursors. The first and second dye compositions can comprise the same or different concentration of dye precursors. The first and second developing compositions can comprise the same or different oxidizing agents.
Alternatively, the method may additionally comprise the step of mixing a first dye composition with a first developing composition to obtain the first composition, the first dye composition comprising one or more oxidizing dye precursors and / or one or more alkalizing agents, and the first developer composition comprises one or more oxidizing agents and in step ii), a first portion of the first composition can be applied to the hair, for example, the hair root and a second portion of the first composition can be retained and the method may further comprise the step of adding a pH reducing agent to the second portion of the first composition to obtain the second composition. The step of adding a pH reducing agent to the second portion of the first composition to obtain the second composition can be carried out between steps ii) and iii).
[0041] The method may additionally comprise the waiting steps for a period of time from 10 min to 40 min, or from 15 min to 30 min, or from 20 min, which is carried out between steps ii) and iii), and waiting for a period of time from 5 min to 20 min, or 10 min, which is done between steps iii) and iv).
[0042] Alternatively, the step of adding a pH reducing agent to the second portion of the first composition to obtain the second composition can be carried out immediately after step ii) and immediately before step iii) and the method may additionally comprise the waiting step for a period of time from 5 min to 40 min, or from 20 min to 40 min, or 30 min, which is performed between steps iii) and iv).
[0043] 90% to 10% or 80% to 50%, or 75% to 55% by weight of the first composition can be applied as a first portion on the hair.
[0044] The first and / or second dye compositions can be mixed, respectively, with the first and / or second developer compositions in a mixing ratio of 2: 1 to 1: 2 or 1: 1.
[0045] In the modalities in which the pH reducing agent is supplied as a liquid, the pH reducing agent: second mixing ratio of the first composition can be less than 1: 4 or less than 1:10.
[0046] In embodiments where the pH reducing agent is supplied as a liquid, the pH reducing agent: second mixing ratio of the first composition can be 1: 4 or more, or 1: 4 to 25: 1, or 1: 4 to 20: 1 or 1: 4 to 10: 1 or 2: 1 to 5: 1. Although not intended to be bound by theory, it is believed that with such a mixing ratio the pH reducing agent will also act as a diluter that will reduce the total concentration of active species, such as dye precursors, oxidizing agents such as hydrogen peroxide and alkalizing agents and therefore will also contribute to the reduction of dye deposition in the hair.
[0047] The first and / or the second developer compositions may comprise from 1 to 20% by weight of the oxidizing agents. The first and / or second dye compositions comprise from 0.01% to 10% by weight of the oxidant dye precursors and / or from 0.1% to 10% by weight of the alkalizing agents.

[0121] The first and / or second hair dyeing compositions of the present invention may additionally have an ionic strength, as defined herein, of less than 1.35 mol / kg, alternatively from 0.10 to 0, 75 mol / kg, alternatively from 0.20 to 0.60 mol / kg. Although not adhering to the theory, it is believed that the value of ionic strength can also affect the resulting viscosity and adhesion properties of the composition to the root. Ionic strength can be affected by salt sources, such as dyes, sodium sulfate, ammonium carbonate, antioxidants and chelators, such as EDDS. The dye tends to have the greatest effect on ionic strength and, therefore, the quantities added in order to provide any particular shade, must be considered in terms of ionic strength, as well as the result of the dye, in order to avoid problems of viscosity and root adhesion.
[0122] The ionic strength of the composition is a function of the concentration of all ions present in that solution and is determined according to the formula:
where mi = molality of ion i (M = mol√Kg H2O), zi = charge of that ion, and the sum includes all the ions in the solution. For example, for a 1: 1 electrolyte, such as sodium chloride, the ionic strength is equal to the concentration, but for MgSO4 the ionic strength is four times higher. Generally, multivalent ions contribute strongly to ionic strength.
[0123] For example, the ionic strength of the mixed solution of 0.050 M Na2SO4 and 0.020 M NaCl is: I = 1/2 ((2 x (+1) 2 x 0.050) + (+1) 2 x 0.020 + (- 2) 2 x 0.050 + (-1) 2 x 0.020) = 0.17 M. Foam
[0124] The first and / or second hair dye compositions of the invention can be supplied in the form of foam which is applied to the hair. Foaming is generally achieved by using a foaming agent incorporated into the mixed composition (typically present in the oxidizing composition or in the dye composition or both) in combination with a manually operated foaming device. Such manually operated foaming devices are known in the art and include aerosol devices, foaming juicer and foaming pump.
[0125] Suitable foaming agents include surfactants, such as anionic, nonionic and amphoteric surfactants, with nonionic surfactants being preferred; polysaccharides (as described in this document); polyvinyl pyrrolidone and its copolymers; acrylic polymers, such as acrylates copolymer (Aculyn 33) and Acrylates / Estearet-20 methacrylates (Aculyn 22); C12-C24 fatty acids, such as stearates and mixtures thereof. Viscosity
[0126] The developing composition and the dye composition can, independently of each other, be prepared as so-called non-viscous liquids or creams.
[0127] Each of the hair dyeing compositions, the first and the second, can have a viscosity that induces a shear stress of 20 to 200 Pa in 10 s-1, measured in accordance with the viscosity test method.
[0128] The first composition for hair dyeing may have a viscosity that induces a shear stress of 20 to 200 Pa in 10 s-1, measured in accordance with the viscosity test method and the second composition for hair dyeing may have a viscosity that induces a shear stress of 20 to 180 Pa in 10 s-1, measured in accordance with the viscosity test method, for example, in modalities in which the pH reducing agent is supplied as a liquid, being that the ratio of pH-reducing agent: second portion of the first composition is 1: 4 or more, or 1: 4 to 25: 1 or 1: 4 to 20: 1 or 1: 4 to 10: 1 or 2: 1 to 5: 1.
[0129] Each of the hair dyeing compositions, the first and the second, can have a viscosity that induces a shear stress of 20 to 60 Pa in 10 s-1, when the first and the second hair dyeing compositions they are applied to the hair with a container to which a nozzle or separate applicator device is attached, such as a comb or brush.
[0130] The hair dyeing composition may have a viscosity that induces a shear stress of 30 to 200 Pa in 10 s-1, or 100 to 200 Pa in 10 s-1, or 130 to 180 Pa in 10 s-1, when the first composition for hair dyeing is applied to the hair with a brush and bowl applicator. The second composition for hair dyeing may have a viscosity that induces a shear stress of 20 to 180 Pa in 10 s-1, or 40 to 180 Pa in 10 s-1, or 70 to 170 Pa in 10 s- 1, when the second composition for hair dyeing is applied to the hair with a brush and bowl applicator or with the user's hands and fingers.
[0131] While not sticking to theory, it is believed that providing the first hair dyeing composition having viscosity values as described above, allows the first hair dyeing composition to be applied directly to the root without any dripping or dripping. by the length of the hair and also allows the second composition for hair dyeing to be easily applied and distributed over the entire remaining length of the hair with minimal or no dripping from the hair. Means of application
[0132] Both the first and / or the second hair dye compositions can be applied to the hair with a brush and bowl applicator. Alternatively, the first hair dye composition can be applied to the hair with a brush and bowl applicator, while the second hair dye composition can be applied to the hair with the user's hands and fingers.
[0133] Alternatively, both the first and / or the second hair dyeing compositions can be applied to the hair with a container to which a nozzle or a separate applicator device, such as a comb or brush, is attached.
[0134] Means of application may also include means that assist in obtaining specific effects, such as lighting effects such as combs, brushes and utensils, aluminum foils for lighting purposes, and caps for lighting effects. Additional application media technologies can be used to assist product penetration into the hair. Examples of these technologies include heating devices, ultraviolet light devices and ultrasound devices. Kit for hair dyeing
[0135] The present invention also relates to a kit for dyeing hair that can be used to carry out the method for dyeing hair described above. The compositions included in the kit can comprise any of the ingredients disclosed in the hair dyeing compositions section of this application.
[0136] The kit may comprise a first dye composition, a second dye composition, a first developer composition and a second developer composition, each of the dye compositions, the first and the second, comprising one or more precursors of oxidizing dye and / or one or more alkalizing agents, and each of the developing compositions, the first and the second, comprises one or more oxidizing agents, the pH of the second developing composition being lower than the pH of the first developing composition.
[0137] Alternatively, the kit may comprise a first dye composition, a first developer composition and a pH reducing agent, the first dye composition comprising one or more oxidizing dye precursors and / or one or more alkalizing agents, and the first developer composition comprises one or more oxidizing agents, the first dye composition, the first developer composition and the pH reducing agent being packaged separately. In these embodiments, the pH reducing agent can be supplied as a solid or as a liquid.
[0138] The developing composition can comprise from 1 to 20% by weight of the oxidizing agents and the dye compositions can comprise from 0.01% to 10%, by weight, of the oxidizing dye precursors and / or 0.1% 10% by weight of the alkalizing agent.
[0139] The kit may additionally comprise a shampoo for use in rinsing the hair after dyeing and / or a conditioning composition.
[0140] The kit can also comprise a color-renewing composition. Such a color-renewing composition can comprise at least one preformed dye and can be applied to the hair immediately after the oxidizing dye. This is typically during the next wash cycle (s) from 1 day to 60 days after the original oxidizer application. This color-renewing composition can be used to increase the initial color obtained and / or reinforce the color during the washing and combing cycle until the next dyeing or lightening event.
[0141] The present invention can be used in various packaging and dispensing devices. Such dispensing devices may be in the form of separate devices that can be used independently or in combination with one another. Typically, hair dyeing or lightening compositions are confined in separate containers with one or multiple compartments, so that the compositions can be stored separately from one another before use. The compositions are then mixed together by means of mixing and then applied to the consumer's hair by means of application.
[0142] The developing composition (s), the dye composition (s) and the pH reducing agent can be supplied in separate containers in the kit. The developer composition (s), the dye composition (s) and the pH reducing agent can be supplied in a bottle, tube, aerosol, or sachet.
[0143] The consumer can mix the developing composition (s) and the dye composition (s) by any means. This may simply involve the use of a mixing bowl into which the compositions are dispensed and then mixed, preferably with the use of a mixing medium, such as an instrument. Alternatively, this may involve adding one of the compositions to the container containing the other composition (typically the dye composition is added to the developing composition), followed by manual stirring or mixing with an instrument. Another system involves the perforation or removal of a seal located between the separate compartments of the dye composition and the developing composition within a single container or sachet, followed by manual mixing within the container or in a separate and / or additional container .
[0144] The hair dye kit can additionally comprise an applicator. The applicator can be a brush and bowl applicator. Alternatively, the applicator can be a nozzle that can be fixed in one of the containers included in the kit, if the developer composition, the dye composition and the pH reducing agent are supplied in separate containers in the kit, or in a separate applicator device. , such as a comb or brush. Such combs and brushes can be adapted in order to achieve specific effects, whether it is fast and uniform coverage or retouching of the root / root line, lighting effects or stripes.
[0145] Alternatively, one of the containers can be provided with a comb attached to, or in place of, the dispensing nozzle, so that the product is dispensed through hollow tips or dispensing holes located in the teeth of the comb. The comb teeth can be provided with single or multiple openings along them, to improve product application and uniformity, especially from root to tip. The dispensing of the product can be obtained by means of mechanical pressure applied to the container, for example, flasks or any of the mechanisms previously described in this document. The comb can be supplied in the container in order to facilitate the application, and can be positioned vertically (called "verticomb" - "vertical comb") or at an angle that allows the consumer to have access to all areas.
[0146] The volume of the developer composition in the kit can be from 10 ml to 120 ml, preferably 40 ml to 70 ml, more preferably 55 ml to 65 ml. The volume of the dye composition in the kit can be from 10 ml to 120 ml, preferably 40 ml to 70 ml, more preferably 55 ml to 65 ml.
[0147] The kit's compositions can be manufactured using any of the standard approaches, these including: a) "oil in water" process, b) "phase inversion" process and c) "one-pot" process (on the same equipment). For example, when using the "oil in water" process, the surfactants of the present invention are added to approximately 50% of the total amount of water in a composition at 90 ° C, homogenized for 15 to 30 min, then cooled until room temperature to form a premix; this premix is then cold mixed with the remaining amounts of water, other optional components and / or oxidizing agents, thus forming the developer composition and dye composition of the dyeing kit described above.
[0148] The kit can additionally comprise a set of instructions comprising instructing the user to dye their hair according to the method defined above.
[0149] For the modalities in which the kit comprises a first and a second developing composition and a first and a second coloring composition, the set of instructions may comprise: i) mixing the first coloring composition with the first developing composition to obtain a first hair dye composition; ii) apply to the hair a portion or all of the first composition for dyeing; iii) mixing the second dye composition with the second developer composition to obtain a second hair dye composition; iv) applying a portion or all of the second composition for dyeing to the hair; v) optionally, rinse the hair.
[0150] For the modalities in which the kit comprises a first dye composition, a first developer composition and a pH reducing agent, the set of instructions may comprise: i) mixing the first dye composition with the first developer composition to obtain the first hair dye composition; ii) applying a first portion of the first hair dyeing composition to the hair and retaining a second portion of the first hair dyeing composition; iii) adding a pH reducing agent to the second portion of the first hair dye composition to obtain the second hair dye composition; iv) applying a portion or all of the second dyeing composition to the hair; v) optionally, rinse the hair.
[0151] The instruction set can comprise any additional steps that are revealed above in the application section concerning the method for dyeing hair. Viscosity test method:
[0152] The viscosity of a composition is measured using a TA Instruments "AR 2000 Rheometer" rheometer or equivalent device equipped with a Peltier plate and a 6 cm checkered acrylic flat plate. The instrument is calibrated according to the manufacturer's instructions and the Peltier plate is adjusted to 25.0 ° C. The cone is raised to a position approximately 4.5 cm above the plate.
[0153] Immediately after mixing, approximately 10 g of the mixture is transferred carefully to the center of the Peltier plate using a spatula. The cone is lowered to obtain a specified gap between the tip of the cone and the upper surface of the Peltier plate. The span configuration is specified by the cone manufacturer and is typically around 1000 micrometers. The rheometer is programmed to operate in rotational mode with a shear stress increasing from 0.1 to 600 Pa for a period of 4 minutes, terminating at 1000 reciprocal seconds. The rotation starts immediately after the specified span is established. The viscosity data collected during the measurement period are shear stress (Pa) plotted as a function of the shear rate (s-1). Color variation test method.
[0154] The colorimetric parameters in the CIE L * a * b * system are measured using an Ocean Optics USB 2000+ spectrophotometer. (illuminant D65, 10 ° angle, specular component included) where L * represents the luminosity of the color, a * indicates the green / red axis and b * the blue / yellow axis. The L *, a * and b * values are average values, the measurement being performed in about 80 different positions of a hair sample by the spectrophotometer.
[0155] 3 g of the hair dyeing composition to be tested are applied with a brush to a 0.75 g, 10 cm (4 inch) non-dyed hair sample, natural white, available from International Hair Importers & Products , Glendale, NY and maintained for 30 minutes at 30 ° C. After 30 minutes the hair dyeing composition is rinsed from the hair for 2 minutes and the hair is then washed with the Wella Professionals Brilliance shampoo, Fine / Normal, commercially available in Germany in April 2014 and conditioned for 1 minute with the Wella conditioner Professionals Brillance, Fine / Normal, commercially available in Germany in April 2014, and then air-dried. Calculated parameters (AL * and AE00 *):
[0156] The parameters AL * and AE00 * are calculated, which correspond, respectively, to the difference in color luminosity and the color variation between the hair dyed with the second composition for dyeing hair according to the present invention, and the hair dyed with the first hair dyeing composition according to the present invention.
[0157] AL * is obtained by the following formula:
where L1 * represents the luminosity of the color measured in hair dyed with the first composition for hair dyeing according to the present invention, and L2 * represents the luminosity of the color measured in hair dyed with the second composition for hair dyeing according to the present invention.
[0158] AE00 * is a well-established parameter. This parameter is calculated based on the colorimetric parameters in the CIE L * a * b * system, which are measured for the first and second hair dye compositions. The method for calculating this parameter is disclosed in Publication 142-2001 of the CIE (Commision Internationale L'Eclairage - International Lighting Commission). Experimental data:
[0159] All concentrations are mentioned as% by weight, except where otherwise specified. Dye compositions:
[0160] Dye composition 1: Wella Koleston Perfect Vibrant Reds 55/46 commercially available in Germany in April 2014

Dye composition 3:
Revealing compositions
[0161] Developing composition 1 Perfect, 6% H2O2 commercially available April 2014
[0162] Developing composition 2: Perfect, 9% H2O2 commercially available April 2014 Developing composition 3:

[0163] In a first experiment, 10 different hair dye compositions (compositions C1 to C10) were prepared by mixing dye composition 1 with developer composition 1 in a 1: 1 mixing ratio in a bowl (5 g dye composition 1 + 5 g of the developer composition). The pH of the different compositions for hair dyeing that were obtained was adjusted by adding sodium hydroxide (50% solution) or phosphoric acid (PA ACS) except one composition (blank sample) to obtain different compositions having different pH values .
[0164] In a second experiment, 10 different compositions for hair dyeing (compositions C11 to C20) were prepared following the same experimental protocol as the first experiment, replacing dye composition 1 with dye composition 2 and developer composition 1 with composition revealing 2.
[0165] In a third experiment, 10 different compositions for hair dyeing (compositions C21 to C30) were prepared following the same experimental protocol as the first experiment, replacing dye composition 1 with dye composition 3 and developer composition 1 with composition revealing 3. Compositions prepared in the first, second and third experiments:


[0166] The parameters L *, a *, b * were measured for the different compositions C1 to C30, in accordance with the color variation test method and the parameters AL * and AE00 * were calculated for some of the compositions, in compliance with the color variation test method. Results:
[0167] The parameters AL * and AE00 *, which correspond, respectively, to the difference in color brightness and to the color variation between the hair dyed with two different compositions, were calculated in accordance with the color variation test method. If necessary, additional AL * and AE00 * parameters can be calculated. As can be seen in the tables below, some of the compositions have an AE00 * value greater than or equal to 1.
[0168] As explained above, although not intended to be bound by theory, it is believed that such AE00 * color variation helps to ensure that the overall color result obtained with the second composition is significantly different from the overall color result obtained with the first composition.
[0169] In addition, some of the compositions additionally have an AL * value greater than 0. These compositions, for example, can be used to provide a lighter color result when the second composition is applied to the hair than when the first composition is applied to the hair, for example, on the length and tip versus hair root.





[0170] The dimensions and values disclosed in the present invention should not be understood as being strictly limited to the exact numerical values mentioned. Instead, except where otherwise specified, each of these dimensions is intended to mean both the mentioned value and a range of functionally equivalent values in value. For example, a dimension revealed as "40 mm" is intended to mean "about 40 mm".
