Abstract
An improved rearranging composition and permanent waving process is disclosed. The improved waving process produces hair that is characterized as thicker, more full bodied with improved humectant properties and requiring significantly less maintenance than is typically required when conventional waving processes are used. The waving process is a step by step procedure involving the addition of a rearranger, a wrapping lotion, and a neutralizer, in combination with intermittent rinsing. The improved quality and settability of the hair is believed to be attributable to the improved rearranging composition. The rearranging composition comprises a homogeneous mixture of a salt of thioglycolic acid and a homopolymer of methylacrylamidopropyltrimethyl ammonium chloride (MAPTAC). A preferred rearranging composition includes a weight ratio of ammonium thioglycolate to monoethanolamine thioglycolate of from about 4:6 to about 7:3 and between about 1.0 to about 3.0% by weight of a cationic homopolymer of MAPTAC. The rearranging composition should also be pH adjusted to between about 3.0 to about 10.5.
