ABSTRACT:
Systems and methods for curling hair and for straightening hair are disclosed, wherein the systems contain, as a principal active ingredients thereof, guanidine hydroxide, together with an ion exchange resin. The guanidine hydroxide is prepared by mixing together in an aqueous medium at least one water-soluble guanidine salt and at least one particulate, strong-base, quaternary ammonium, hydroxide-form ion-exchange resin. After the mixed components have had a chance to undergo ion exchange, the composition is applied to hair which is maintained in a desired configuration, and after the composition has been in contact with the hair for an effective time the composition is removed from the hair, thereby causing the hair to maintain such desired configuration.
