Abstract
By providing high absorbent end wraps staturated with a disulfide, the action of the reducing agent on the porous ends of the hair is controlled, typical overprocessing of the hair ends is eliminated, and a uniform permanently waved head of hair is obtained. Preferably the disulfide saturated into the end wraps is the disulfide of the mercaptan used in the permanent waving lotion.
