Title : PERMANENT WAVING COMPOSITIONS AND METHOD ABSTRACT The waving composition of this invention com- prises about 0.03 to about 0.06 mole of thioglycolic acid, about 0.06 to about 0.12 mole of total ammonia, about 0.01 to about 0.06 mole of free ammonia and about 0.01 to about 0.06 mole of a carbonate per 100 ml of the composition and has a pH of about 7.4 to about 8.0 at 25°C. The method of this invention comprises applying the permanent waving composition to the hair at room temperature before, during and/or after winding the hair, treating the hair for about 5 to about 30 minutes in an atmosphere having a temperature of about 40 to about 60°C and over-saturated with moisture, and hardening the hair by oxidation. This invention gives uniform wavings without causing over-waving and damage to the hair and skin.
