ABSTRACT:
A mild, alkaline permanent wave reducing composition and method of permanently waving or reshaping human hair that provides a strong, long lasting curl like an alkaline permanent wave composition but leaves the hair soft like an acid permanent wave composition and leaves essentially no post-perm odor. The composition contains about 2.0% to about 6.5% by weight of a cysteine reducing agent compound selected from the group consisting of cysteine, a cysteine salt, and mixtures thereof; about 4.5% to about 8.0% of a thioglycolate; and sufficient additional alkali, if necessary, to bring the pH of the composition within the rang of about 7.5 to about 9.5.
