ABSTRACT:
A permanent wave method includes a first step of applying a reducing agent (12) to hair (10) to be permed. At this point of time the hair (10) is not yet curled around a rod and is still straight. Then, the hair is covered with a cap of vinyl, and is left in this condition until the hair is brought into a first reduced condition in which the hair is sufficiently soft and plastic to be wrapped around a rod without cracking or straining. Thereupon, the reducing agent remaining on the hair is washed away. Then, the hair is wrapped, or curled, around a rod (13), and is covered with a vinyl cap (16). Thereupon, the hair is heated in its entirety, from its root up to its end. As a result, the hair is brought into a second reduced condition in which the hair is locked in the curled pattern about the rod (13). Then, cap (16) is removed. Then, an oxidizing agent (17) is applied to the hair, and is left in this condition until the hair has been locked into a more stable curled pattern. Thereafter, rod (13) is removed from the hair, and the hair is then washed with water and is allowed to dry, completing the process of making a permanent wave. Permanent wave apparatus may be used to determine automatically whether the reduction reaction initiated in the hair by application of the reducing agent thereto has resulted in the first reduced condition of the hair. The apparatus comprises a temperature sensing device (21), a temperature indicating/alarm device (22), and a thermal insulation cap (36).
