| abstract |
Compositions, kits, and methods for bonding, for example, disulfide bonds, to hair or skin are disclosed. The compositions provide an enhanced emollient benefit for dry hair or moisturize the skin. The compositions also provide a long lasting moisturizing and softening effect on the skin or hair, without any greasy feeling. The compositions contain one or more compounds that covalently bind at least two thiol groups to the hair or skin. Use of the bonding compositions prevents the repair of the repaired bonds to their free thiol state for at least a week or a month or more after simple application of the composition. Improved methods of hair styling are also provided, for example permanent waving, hair curling, dyeing or for hair straightening and straightening. |
