Abstract
A combination of chemicals and electromagnetic radiation is used to alter the physical characteristics of keratinic fibers such as mammalian or human hair. A non-irritating, non-reactive disulfide in the form of a solution or gel is first contacted with the hair. Electromagnetic radiation is then applied to the hair to photochemically convert the disulfide into a dithiol. The dithiol breaks the disulfide bonds in the hair so that the hair can be permanently re-shaped.
