Methods for Fixing Hair and Skin
First Claim
1. A method for treating hair, wherein the hair comprises two or more reduced thiol groups, comprising:
- (a) applying to the hair a formulation comprising a crosslinking agent in an effective amount to covalently crosslink the reduced thiol groups,wherein the crosslinking agent comprises at least two reactive moieties capable of reacting with the reduced thiol groups, and optionally a linker that links the reactive moieties, and the reduced thiol groups are crosslinked via the crosslinking agent at a temperature from about 20°
C. to about 35°

Abstract
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 crosslink at least two thiol groups in the hair or on the skin. Use of the crosslinking compositions prevents reversion of the repaired bonds to their reduced (thiol) state, for at least one week, one month, six months, or one year, after a single application of the composition. Improved methods of styling hair, for example permanent hair waving, hair curling, and hair straightening are also provided.
