ABSTRACT:
A process for permanent waving of hair by a reaction in which cystine bridges are reduced to cysteine, the hair reshaped, and the reaction reversed. The improvement in the process resides in the step of reducing or reversing the reaction by applying to hair a composition which includes an emulsion polymerized mercapto functional silicone. Permanent hair waving with waving lotions, neutralizing solutions, or both, containing such emulsion polymerized mercapto functional silicones, provide waved hair with improved conditioning benefits.
