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 reversing the reaction by applying to hair a composition which includes a vinyl functional silicone, a solvent, and a catalyst. The catalyst is either a carboxylic acid salt of a metal or a metal carbonyl compound. Both cyclic and linear vinyl functional silicones can be employed. Permanent hair waving neutralizer compositions are also described.
