The subject of the invention is a composition for treating keratin fibers, comprising one or more oxyalkylenated fatty amide(s) of formula (I), one or more oxyalkylenated fatty alcohol(s), and one or more chemical oxidizing agent(s); it being understood that the oxyethylenated fatty alcohol(s)/oxyethylenated fatty amide(s) of formula (I) weight ratio is less than or equal to 1 and that the pH of the composition is less than or equal to 5.

Compositions, kits, and methods for repairing bonds, for example, disulfide bonds, in hair or on the skin are disclosed. The compositions provide improved conditioning benefit for dry hair or moisturize the skin. The compositions also provide a long lasting moisturized feel and smooth feel to the skin or hair, without feeling greasy. The compositions contain one or more compounds that covalently bind at least two thiol groups in the hair or on the skin. Use of the binding compositions prevents reversion of the repaired bonds to their free thiol state, for at least one week or one month, or more, after a single application of the composition. Improved methods of styling hair, for example permanent hair waving, hair curling, hair coloring or highlighting, and hair straightening, are also provided.

The instant disclosure relates to methods for treating chemically relaxed hair. The methods include applying a neutralizing composition to the chemically relaxed hair, the neutralizing composition comprising: at least 0.5 wt. % of at least one carboxylic acid, one or more C.sub.2-C.sub.6 monoalkanolamines, and water. The neutralizing composition is allowed to remain on the hair for a period of time. The hair is also treated with a neutralizing conditioner, which is a different than the neutralizing composition. The neutralizing conditioner includes: at least 0.5 wt. % of at least one carboxylic acid, one or more C.sub.2-C.sub.6 monoalkanolamines, one or more cationic surfactants, and water. The neutralizing conditioner is allowed to remain on the hair for a period of time. After treatment with a neutralizing composition and a neutralizing conditioner, the hair may be further treated with a shampoo, a conditioner, a conditioning shampoo, etc., dried, and/or styled.

The invention relates to a process for straightening keratin fibres, comprising: (i) a step in which a straightening composition containing at least two denaturing agents is applied to the keratin fibres, (ii) a step in which the temperature of the keratin fibres is raised, using a heating means, to a temperature of between 110 and 250° C.

Formulations, kits, and methods for rebuilding the disulfide bonds in keratin found in hair, skin, or nails. Hair that is damaged due to a hair coloring treatment and/or other reducing treatment, such as during a permanent wave, can be treated with the formulations containing one or more active agents. The formulations may be applied subsequent to a hair coloring treatment or simultaneously with a hair coloring treatment. Use of the active agent formulations during a permanent wave treatment prevents the reversion of the hair to its previous state, for at least one week, preferably at least three months, more preferably at least one year, most preferably greater than one year, after one or more than one application of the formulation. Application of the active agent formulation to skin or nails can help repair damaged disulfide bonds due to natural wear and tear or natural aging.
