Abstract: An improved wrapping lotion and permanent waving process is disclosed. The improved waving process produces hair styles characterized as bouncier, more full bodied with an open/looser pattern of curls. The waving process is a step-by-step procedure involving the addition of a rearranger, a wrapping lotion, and a neutralizer, with intermittent rinsing between. The improved quality and setability of the hair is believed attributable to the improved wrapping lotion composition that comprises a homogenous mixture of a guar component and a salt of thioglycolic acid. A preferred wrapping lotion composition includes between about 0.2 and about 2.5% by weight of a nonionic hydroxypropylated guar and between about 0.3 and about 7.0% ammonium thioglycolate. The wrapping lotion composition should also be pH adjusted to between about 7.0 and about 10.5 and have a viscosity in the range from about 500 cps to about 12,000 cps.
