    摘要: A method for dyeing hair is disclosed. The method comprises (1) treating hair with an oxidative colorant agent (A); (2) subsequent to (1), treating the hair with a CH-acidic hair dyeing agent (B); and (3) subsequent to (2), treating the hair with a cosmetic decolorizing agent (Ox). The method comprises a time interval between (1) and (2) of from about 1 minute to about 1.5 months, and a time interval between (2) and (3) of from about 1 minute to about 1.5 months. A process for multitonal dyeing of hair is also disclosed. The process comprises preparing an oxidative colorant agent (A); treating hair with the agent (A) to give a colored hair; preparing a CH-acidic hair dyeing agent (B); treating the colored hair with the agent (B) to give a dyed hair; and treating the dyed hair with a cosmetic decolorizing agent (Ox) to give a multitonal dyed hair.

    摘要: 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.
