Abstract
A leave-on oxidizing solution useful for permanent waving of hair containing water, an oxidant which is capable of being left on the hair and dried on the hair without damage to the hair, and an acidic agent to provide the solution with a pH value of less than about 7. The use of the leave-on oxidizing solution decreases the amount of time required for carrying out a permanent waving of hair process.
