Description

Title of the invention: COMPOSITIONS AND METHODS FOR PROCESSING KERATIN FIBERS technical field

[0001] This disclosure relates to compositions and processes for treating keratin fibers, such as hair, for example to repair damaged keratin fibers, provide strength to keratin fibers and / or to reduce the elasticity of keratin fibers. CONTEXT

[0002] Consumers wish to use cosmetic compositions and processes to change or improve the appearance of their hair, for example, by altering the color, style, and / or shape of the hair, and / or by imparting various properties to the hair, such as shine and revitalization. However, many compositions and processes for altering the appearance of hair, such as permanent color or shape modification compositions and processes, involve harsh chemical treatments. In addition, repeated styling can cause hair damage, for example, due to the repeated use of heat and styling tools. All these processes can break the bonds within the hair fibers, which, if not reformed, result in damaged hair.

[0003] For example, hair lightening and dyeing compositions and processes generally require the presence of a strong alkalizing agent such as ammonia, as well as additional compounds such as oxidizing agents. In order to change the color of the hair, these components must first break down the natural components of the hair fibers. Similarly, straightening, relaxing, and perming compositions also involve aggressive chemicals to alter the shape of the hair by breaking the disulfide bonds in the hair fibers.

[0004] It is known that, although such processes effectively alter the color and shape of hair, the chemical agents used inherently cause damage to the hair and negatively impact the strength, elasticity, and porosity of the hair fibers. For example, hair that has been bleached, dyed, straightened, smoothed, curled, repeatedly styled, etc., is often dry, frizzy, and generally appears unhealthy to the touch and in appearance. Furthermore, damaged hair is brittle and / or exhibits increased elasticity, resulting in more frequent breakage. As such, consumers Consumers are looking for compositions and processes to prevent or minimize such damage and / or to repair hair that has been damaged by these treatments and processes. In particular, they want strong hair that doesn't break easily, that can be stretched or manipulated while retaining the ability to return to its original state without breaking (i.e., with reduced elasticity), that is soft and healthy to the touch, and that also looks shiny and healthy.

[0005] However, it has proven difficult to formulate compositions that satisfactorily meet these requirements. For example, some compositions that attempt to solve the problem simply coat the hair with compounds that may improve its feel and appearance; however, this approach is only temporary and superficial. Rather than preventing or repairing hair damage, this approach merely masks the damage until the next rinse or wash. Other compositions attempt to treat the damage within the hair fiber, but have not been satisfactory to date.

[0006] The present inventors have now discovered a synergistic combination of components that is remarkably effective in preventing or minimizing hair damage and treating damaged hair. Hair treated with compositions according to the disclosure shows remarkably reduced signs of damage, including increased strength and / or reduced elasticity, particularly hair that has been damaged by harsh chemical treatments such as bleaching, dyeing, perming, straightening, relaxing, etc. SUMMARY

II. PROCESSES

[0160] The disclosure also relates to processes for treating keratin fibers, such as hair. Hair treatment processes may include processes for reducing or preventing hair damage, protecting hair from damage, restoring the moisture balance of hair fibers, strengthening hair fibers, improving the elasticity of hair fibers, and / or maintaining the balance, strength, and / or elasticity of hair fibers. In some embodiments, the hair treatment processes prevent hair damage from becoming too extensive to repair, namely, they prevent irreversible hair damage.The processes include applying a composition as disclosed to the hair, optionally leaving the composition on the hair for a period ("treatment period", "resting period" or "leave-on period"), and optionally rinsing the hair to remove the composition.

[0161] The application period may last for a period deemed appropriate to allow the active agents to provide benefits to the keratin fibers, such as approximately 30 seconds, approximately 1 minute, approximately 2 minutes, approximately 5 minutes, approximately 10 minutes, approximately 15 minutes, approximately 20 minutes, approximately 30 minutes, approximately 45 minutes, approximately 1 hour, approximately 2 hours, etc., or may extend over a period of exposure time using any of the preceding values ​​as upper and lower limits. As a non-limiting example, the exposure time can range from approximately 30 seconds to approximately 60 minutes, from approximately 30 seconds to approximately 45 minutes, from approximately 30 seconds to approximately 30 minutes, from approximately 30 seconds to approximately 20 minutes, from approximately 30 seconds to approximately 15 minutes, from approximately 30 seconds to approximately 10 minutes, from approximately 30 seconds to approximately 5 minutes, and from approximately 1 minute to approximately 60 minutes, from approximately 1 minute to approximately 45 minutes, from approximately 1 minute to approximately 30 minutes, from approximately 1 minute to approximately 20 minutes, from approximately 1 minute to approximately 15 minutes, from approximately 1 minute to approximately 10 minutes, from approximately 1 minute to approximately 5 minutes, from approximately 2 minutes to approximately 60 minutes, from approximately 2 minutes to approximately 45 minutes, from approximately 2 minutes to approximately 30 minutes, from approximately 2 minutes to approximately 20 minutes minutes, from approximately 2 minutes to approximately 15 minutes, from approximately 2 minutes to approximately 10 minutes, from about 2 minutes to about 5 minutes, etc.

[0162] In some embodiments, the composition can be left on the hair for a period of several hours, for example overnight. Thus, the application period can be up to about 24 hours, such as up to about 12 hours, for example, can range from about 1 hour to about 12 hours, from about 1 hour to about 10 hours, from about 1 hour to about 8 hours, from about 1 hour to about 6 hours, from about 1 hour to about 4 hours, from about 2 hours to about 12 hours, from about 2 hours to about 10 hours, from about 2 hours to about 8 hours, from about 2 hours to about 6 hours, from about 2 hours to about 4 hours, etc.

[0163] The processes according to the disclosure include the use of the described compositions as a standalone treatment, or as part of a routine that includes one or more additional compositions or treatments. Although not required, various treatments using compositions according to the disclosure may also include a step of heating the hair to which the composition has been applied, for example, during the resting period while the composition is on the hair. For example, a hairdryer, a hair dryer hood, etc., may be used.

[0164] By way of example, a composition according to the disclosure may be applied to hair to repair hair that has been previously damaged by chemical treatment, to improve the overall health and appearance of the hair, to improve the elasticity of the hair fibers, etc., by applying a composition to wet, damp, or dry hair, leaving the composition on the hair for an appropriate treatment time, optionally rinsing the hair, and then optionally drying and / or styling the hair according to the person's habits. This type of treatment may, for example, be carried out in a salon or at home on a weekly, bi-weekly, monthly, etc. to improve the health and overall appearance of the hair.

[0165] In other embodiments, a composition as disclosed may be applied to the hair before, during, and / or after a treatment process that includes one or more other hair compositions. For example, such a routine may include applying a composition as disclosed to wet, damp, or dry hair, leaving the composition on the hair for an appropriate treatment time, and then substantially immediately afterward (i.e., within the same hair cleansing process), with or without intermediate rinsing of the hair, shampooing the hair according to the individual's normal hair cleansing routine.Another routine of this type may include washing the hair with shampoo according to the person's usual hair cleansing routine, and substantially immediately afterwards (i.e., as part of the same hair cleansing process), with or without intermediate rinsing of the hair, the application of a composition as disclosed on the hair, optionally before and / or after the application of a conditioning composition on the hair.Yet another routine of this type may include hair conditioning, for example, a deep conditioning treatment, and substantially immediately before and / or after (i.e., as part of the same hair conditioning process), with or without intermediate rinsing of the hair, the application of a composition as disclosed to the hair, optionally with or without rinsing the hair between the application steps of a conditioning composition and a composition as disclosed. Thus, it is envisaged that compositions as disclosed may be incorporated into a hair cleansing and / or conditioning process.

[0166] In still other exemplary embodiments, a composition according to disclosure may be applied to the hair before, during and / or after a chemical hair treatment process. For example, such a routine may include applying a composition according to disclosure to wet, damp or dry hair, leaving the composition on the hair for an appropriate treatment time, optionally rinsing the hair, and then substantially immediately afterwards (i.e., as part of the same chemical hair treatment process), with or without intermediate rinsing of the hair, applying to the hair a chemical treatment such as a bleaching, dyeing, smoothing, straightening or perming composition.Another routine of this type may include the application of a chemical treatment, such as a bleaching, dyeing, smoothing, relaxing or perming compound, to the hair, and substantially immediately afterwards (i.e. as part of the same treatment process). chemical hair treatment), with or without intermediate rinsing of the hair, involves the application to the hair of a composition as disclosed. Thus, it is envisaged that the compositions disclosed may be incorporated into a chemical hair treatment process, thereby reducing, minimizing, or preventing hair damage that might otherwise result from such harsh chemical treatments.

[0167] Surprisingly, hair treated with the compositions and processes disclosed shows less damage than hair not treated with the compositions and processes disclosed. The reduction in damage is particularly noticeable in hair damaged by harsh chemical treatments, such as bleaching, dyeing, perming, straightening, relaxing, etc., as well as by repeated styling, for example with heat or styling tools. Hair repaired using the compositions and processes disclosed may have lower elasticity and / or higher tensile strength than similarly damaged but untreated hair.

[0168] In this document, the term "salts" throughout the disclosure may include salts containing a counterion such as an alkali metal, an alkaline earth metal, or an ammonium counterion. This list of counterions, however, is not exhaustive. Salts also include a dissociated form of a compound, for example, in an aqueous solution.

[0169] In this application, the terms "keratin fibres" and "hair" are used interchangeably without being intended to be restrictive. A person skilled in the art will understand that keratin fibres include hair, such as hair growing from the scalp.

[0170] As used herein, the expression "apply a composition to the hair," and its variations, is intended to refer to bringing the hair into contact with at least one of the compositions in the disclosure, in any manner whatsoever. It may also refer to bringing the hair into contact with an effective quantity.

[0171] The expression "hair treatment" (and its grammatical variations) as used herein refers to the application of the compositions of this disclosure to the surface of the hair. The expression "hair treatment" (and its grammatical variations) as used herein also refers to bringing the hair into contact with the compositions of this disclosure.

[0172] Unless otherwise defined for any specific embodiment, the expression "substantially free" or "essentially free" as used herein means that there is less than about 5% by weight of a specific material added to a composition, relative to the total weight of the composition. For example, the Compositions may include less than approximately 4%, less than approximately 3%, less than approximately 2%, less than approximately 1.5%, less than approximately 1%, less than approximately 0.5%, less than approximately 0.1%, less than approximately 0.01%, less than approximately 0.001%, or less than approximately 0.0001% of the specified material. As such, it is envisaged that any component described herein for use in hair treatment compositions may be present in the compositions in amounts less than approximately 5%, less than approximately 4%, less than approximately 3%, less than approximately 2%, less than approximately 1%, less than approximately 0.5%, less than approximately 0.1%, less than approximately 0.01%, less than approximately 0.001%, or less than approximately 0.0001%, and the composition will be considered "substantially free" of such material. A composition that is "free" of a component is assumed to contain no quantity of the specified component.However, it is understood that the terms "free" and "substantially free" refer to the amount of a component added to the composition, without including an amount of the component present in the composition as a minor component in a raw material. For example, a composition that is "free" of waxes may not have wax included as an intended component, but may nevertheless contain a pigment coated with wax, since such a wax would be considered a minor component of the pigment material and would not be expected to provide the benefits to the composition that would be anticipated from the inclusion of a wax itself as an intended component.

[0173] As used herein, a "stable" composition maintains a texture that is substantially unchanged, and shows minimal to no phase separation when stored at room temperature for at least one month, preferably at least two months, or at temperatures up to 45°C for at least two weeks. EXAMPLES

[0180] A comparator product, Cl, had the following list of ingredients on its packaging: Water (Aqua), bis-aminopropyl diglycol dimaleate, propylene glycol, cetearyl alcohol, behentrimonium methosulfate, cetyl alcohol, phenoxyethanol, glycerin, hydroxyethyl ethylcellulose, stearamidopropyl dimethylamine, quaternium-91, sodium benzoate, cetrimonium methosulfate, cetrimonium chloride, parfum, tetrasodium EDTA, polyquaternium-37, benzyl benzoate, etidronic acid, ascorbic acid, phytantriol, tocopheryl acetate, Aloe Barbadensis leaf juice, panthenol, Simmondsia Chinensis (jojoba) seed oil, citric acid, potassium sorbate. The composition of Cl, which is described as a “treatment A pre-shampoo hair treatment that reduces breakage and split ends for visibly healthier hair is advertised as part of a system that claims it can "restore broken disulfide bonds damaged by chemical treatments, heat, and styling." Instructions for the Cl formula are to use the product before using the shampoo ("Cl-S") and conditioner ("Cl-C") that are part of this system, both of which list bis-aminopropyl diglycol dimaleate as the active ingredient. Example 2A# - Ultra-bleached hair

[0181] Five strands (S17-S21) of virgin Caucasian hair were bleached with a composition prepared by mixing a commercial bleaching powder with a commercial oxidizing composition (40V hydrogen peroxide) at a mixing ratio of 1:1.5 (bleaching powder:oxidizing composition) and treated at a temperature of approximately 55 °C for approximately 45 minutes. The strands were rinsed, and then four of the strands (S17-S20) underwent the following treatment routines (strand S21 was not treated after the bleaching composition was rinsed from the hair).

[0182] The S17 strand was cleaned with a commercially available shampoo by wetting the strand, applying the shampoo to the strand, working the shampoo into a lather, leaving it on the strand for approximately one minute, and then rinsing the strand until all the shampoo was removed. Immediately afterward, a commercially available conditioner was applied to the strand and distributed to ensure that the hair was completely coated. It was left to rest for approximately five minutes, and then the strand was rinsed thoroughly. This treatment protocol was repeated four more times.

[0183] Strands S18 and S19 were each cleaned with a commercially available shampoo by wetting the strand, applying the shampoo to the strand, working the lather into a lather, leaving it on the strand for approximately one minute, and then rinsing the strand until all the shampoo was removed. Immediately afterward, a commercially available conditioner was applied and distributed to ensure that the hair was completely coated, left to rest for approximately five minutes, and then the strand was rinsed thoroughly. Immediately afterward, one of the compositions 1D (S18) or IB (S19) was applied to the strand and distributed to ensure that the hair was completely coated, left to rest for approximately five minutes, and then the strand was rinsed thoroughly. This treatment protocol was repeated four more times.

[0184] The S20 strand was treated with composition Cl by applying the composition to the strand and distributing it so as to ensure that the hair was completely The hair was coated. The Cl composition was left on the hair for approximately five minutes, then the strand was rinsed thoroughly. Immediately afterward, the strand was washed with Cl-S shampoo by wetting the strand, applying the shampoo, working it into a lather, leaving it on the strand for approximately one minute, and then rinsing until all the shampoo was removed. Next, the Cl-C conditioner was applied to the strand and distributed to ensure complete coverage. It was left on for approximately five minutes, and then the strand was rinsed thoroughly. This treatment protocol was repeated four more times.

[0185] The integrity of the hair fibers of each of the S17-S21 strands was studied, to evaluate the ability of the compositions according to the disclosure to minimize, prevent or repair hair damage.

[0186] The evaluation was performed by stretching a standardized quantity of wet hair fibers, with two experts independently evaluating each strand. The experts were trained to stretch the area of ​​the strand being evaluated by uniformly applying a manual tensile force using their hands / fingers. The behavior of the strand was rated by each expert on a 6-level scale as follows, with the result reported for each strand being the average of the two:

[0187] 0 = Natural and healthy hair (no damage);

[0188] 1 = low elasticity (when stretched, the hair fibers exhibit a slight elasticity, returning to their initial state after testing);

[0189] 2 = moderate elasticity (when stretched, the hair fibers exhibit a elasticity, returning to their initial state after the test);

[0190] 3 = High elasticity (when stretched, the hair fibers exhibit elasticity and some hair fibers do not return to their initial state after the test);

[0191] 4 = Very high elasticity (when stretched, the hair fibers exhibit elasticity (and most hair fibers do not return to their initial state after the test); and

[0192] 5 = Immediate rupture (when stretched, the hair fibers exhibit a high elasticity and break during the test).

[0193] The results showed that the hair fibers of strands S18 and S19, treated with compositions 1D and IB respectively, surprisingly had lower elasticity than the fibers of strands S17 and S20-S21 one day after the end of the treatment protocol ([Fig. 1]). In other words, the hairs of strands S17 and S21 were damaged by the aggressive bleaching process, resulting in increased elasticity, while the hairs of strand S20 were damaged by the aggressive bleaching process but not repaired with the comparative treatment, resulting in reduced elasticity. increased, while the damage to the S18 and S19 wicks had been repaired by treatment with compositions 1D and IB.

[0194] Secondly, strength was evaluated using a Dia-Stron fiber tensile testing instrument called the MTT (Miniature Tensile Tester). The results showed that the hairs in strands S18 and S19, treated with compositions 1D and IB respectively, were surprisingly stronger than the hairs in strands S17 and S20-S21, meaning that a greater force was required to break the individual hair fibers in strands S18 and S19. [Fig. 2A] shows the breaking strength (MPa) for a control strand (CTL), made of the same hair but unbleached, strand S17, which was bleached but without further treatment, and strands S18 and S19, treated with compositions 1D and IB respectively, and strand S20, treated with the comparative compositions. As shown in [Fig.[2A], the breaking strength of the control strand (CTL) was more than double that of strand S17, demonstrating the significant damage caused by the bleaching process. After five (5) treatments with composition 1D (strand S18), IB (strand S19), or the comparative compositions (S20), the breaking strength of the treated strands was increased compared to strand S17. Surprisingly, the increase in breaking strength for strands S18 and S19 was considered statistically significant compared to that of strand S20, meaning that compositions 1D and IB repaired the hair to a greater extent than the comparative compositions.

[0195] Example 2B - Straightened and ultra-bleached hair: Elasticity

[0196] Four strands (S22-S25) of Caucasian hair that had previously been straightened with formaldehyde were bleached with a composition prepared by mixing a commercial bleaching powder with a commercial oxidizing composition (40V hydrogen peroxide) at a mixing ratio of 1:1.5 (bleaching powder:oxidizing composition) and treated at a temperature of approximately 55 °C for approximately 45 minutes. The strands were rinsed and, over a five-week treatment period, the four strands were subjected to the following routine twice a week.

[0197] First, the strands were cleaned with a commercially available shampoo by wetting the strand, applying the shampoo to the strand, working the shampoo into a lather, leaving it on the strand for about one minute, and then rinsing the strand until all the shampoo was removed. Immediately afterward, a commercially available conditioner was applied to the strand and distributed to ensure that the hair was completely coated, and left to rest for about five minutes. minutes, then the strand was rinsed thoroughly. A leave-in conditioning product and a leave-in flat iron serum were applied to the hair.

[0198] Three of the strands (S22-S24) were subjected to the following additional treatment routines once a week during the 5-week period.

[0199] Strand S22 was cleaned with a commercially available shampoo by wetting the strand, applying the shampoo, working it into a lather, leaving it on the strand for approximately one minute, and then rinsing the strand thoroughly. A hair mask was applied and left on the hair, after which the hair was rinsed. Immediately afterward, a commercially available conditioner was applied to the strand and distributed to ensure complete coverage. It was left on for approximately five minutes, and then the strand was rinsed thoroughly. A leave-in conditioner and a leave-in flat iron serum were applied to the hair.

[0200] The S23 strand was cleaned with a commercially available shampoo by wetting the strand, applying the shampoo to the strand, working it into a lather, leaving it on the strand for approximately one minute, and then rinsing the strand until all the shampoo was removed. Immediately afterward, the IC composition was applied to the strand and distributed to ensure that the hair was completely coated. It was left to remain on the strand for approximately five minutes, and then the strand was thoroughly rinsed. Immediately afterward, a commercially available conditioner composition was applied and distributed to ensure that the hair was completely coated. It was left to remain on the strand for approximately five minutes, and then the strand was thoroughly rinsed. A leave-in conditioner and a leave-in flat iron serum were applied to the hair.

[0201] The S24 strand was treated with composition Cl by applying the composition to the strand and distributing it to ensure that the hair was completely coated. Composition Cl was left on the hair for approximately five minutes, after which the strand was thoroughly rinsed. Immediately afterward, the strand was washed with Cl-S shampoo by wetting the strand, applying the shampoo, working it into a lather, leaving it on the strand for approximately one minute, and then rinsing the strand until all the shampoo was removed. Immediately afterward, conditioner Cl-C was applied to the strand and distributed to ensure that the hair was completely coated. It was left to rest for approximately five minutes, and then the strand was washed. was rinsed thoroughly. A leave-in conditioning product and a leave-in straightening serum were applied to the hair.

[0202] After the five-week treatment period, the elasticity of the hair fibers of each of the strands S22-S25 was studied in the same way as described in Example 2A. The results showed that the hair fibers of strand S23, treated with composition IC, had lower elasticity than the fibers of either strand S22 or S24-S25.

[0203] Example 2C - Straightened and ultra-bleached hair: Resistance

[0204] Four strands (S26-S29) of Caucasian hair that had previously been straightened using formaldehyde were bleached with a composition prepared by mixing a commercial bleaching powder with a commercial oxidizing composition (40V hydrogen peroxide) at a mixing ratio of 1:1.5 (bleaching powder:oxidizing composition) and treated at a temperature of approximately 55 °C for approximately 45 minutes. The strands were rinsed and, over a five-week treatment period, all four strands were subjected to the following routine.

[0205] First, the strands were cleaned with a commercially available shampoo by wetting the strand, applying the shampoo, working it into a lather, leaving it on the strand for about one minute, and then rinsing the strand until all the shampoo was removed. Immediately afterward, a commercially available conditioner was applied to the strand and distributed to ensure that the hair was completely coated. It was left to rest for about five minutes, and then the strand was rinsed thoroughly. A leave-in conditioner and a leave-in flat iron serum were applied to the hair.

[0206] Three of the strands (S27-S29) were subjected to the following additional treatment routines once a week during the 5-week period.

[0207] Strands S27 and S28 were cleaned with a commercially available shampoo by wetting the strand, applying the shampoo, working it into a lather, leaving it on the strand for approximately one minute, and then rinsing the strand until all the shampoo was removed. One of the compositions IB (S28) or 1D (S27) was applied to the hair and left on, after which the hair was rinsed. Immediately afterward, a commercially available conditioner was applied to the strand and distributed to ensure that the hair was completely coated, left on for approximately five minutes, and then the strand was rinsed thoroughly. A leave-in conditioner and a leave-in flat iron serum were applied to the hair.

[0208] The strand S29 was treated with composition Cl by applying the composition to the strand and distributing it to ensure that the hair was completely coated. Composition Cl was left on the hair for approximately five minutes, after which the strand was rinsed thoroughly. Immediately afterward, the strand was washed with shampoo Cl-S by wetting the strand, applying the shampoo, working it into a lather, leaving it on the strand for approximately one minute, and then rinsing the strand until all the shampoo was removed. Immediately afterward, conditioner Cl-C was applied to the strand and distributed to ensure that the hair was completely coated, left to rest for approximately five minutes, and then the strand was rinsed thoroughly.A leave-in conditioning product and a leave-in serum for use with flat irons were applied to the hair.

[0209] The MTT tests were carried out in the same manner as described in Example 2A. The results showed that the hairs in strands S27 and S28, treated with compositions 1D and IB respectively, were surprisingly stronger than the hairs in strands S26 or S29, meaning that a greater force was required to break the individual hair fibers in strands S27 and S28. Figure 2B shows the breaking strength (MPa) for a control strand (CTL), made of the same hair but unbleached, strand S26, which was bleached but without further treatment, and strands S27 and S28, treated with compositions 1D and IB respectively, and strand S29, treated with the comparative compositions. In Figure 2B, the breaking strength of the control strand (CTL) was approximately three times greater than that of strand S26, showing the significant damage caused by the bleaching process.After five (5) treatments with composition IB (strand S28) and 1D (strand S27), the breaking strength of the treated strands was increased compared to strand S26, and the improvement was considered statistically significant. However, [Fig. 2B] shows that the breaking strength of the strand treated with the comparative composition (S29) did not show any improvement.

[0210] Examples 2A-2C thus demonstrate that treating hair damaged by aggressive chemical processes with a composition as disclosed remarkably repairs the damage. The damage repair achieved with compositions as disclosed is also remarkably superior to that achieved with a commercial product that claims to do the same. Example 3 - Compositions

[0211] Compositions 2A-2F according to the disclosure were prepared as indicated in Table 2.

[0213] Compositions 2A-2F, which contained a synergistic combination of active components (carboxylic acids (citric acid), osmolytes (glycine betaine), and amino acids (arginine)) and were stable due to the presence of cationic surfactants (cetrimonium chloride, behentrimonium chloride, and / or stearamidopropyl dimethylamine), were also expected to minimize, prevent, and / or repair hair damage. The compositions were also expected to improve the elasticity and tensile strength of the treated hair fibers. Example 4# - Additional Compositions

[0214] The following compositions, according to the disclosure, may be prepared and are expected to be similarly stable and to minimize, prevent, or repair damage to the hair. The compositions should also improve the elasticity and tensile strength of the treated hair fibers.

[0216] The examples above demonstrate that the synergistic combination of active components (carboxylic acids, osmolytes, and amino acids) as disclosed surprisingly and unexpectedly repairs damaged hair and prevents or minimizes further hair damage. The cationic surfactants remarkably provide stability to the compositions despite the presence of relatively high amounts of these active components.
