AMMONIUM THIOGLYCOLATE SOLUTION IN HEAT-ASSISTED PERMANENT WAVING

摘要

A heat-assisted ammonium thioglycolate permanent waving system is provided in which heat-containing clamps applied to the hair to assist the action of the ammonium thioglycolate bring the hair up to hair waving temperature and maintain it at such temperature for no more than six minutes and in which the ammonium thioylycolate solution is weaker than is used in non-heat-assisted permanent waving for the same type of hair and stronger than has been used in prior heat-assisted permanent waving for the same type of hair.
