Abstract
Abstract A method of setting hair or fur comprises applying to the hair or fur a composition for reducing keratin disulfide bonds, allowing the hair or fur to stand in a desired configuration, applying to the hair or fur a composition to set the hair or fur in a desired wave or straightened configuration, and washing or drying the hair or fur, where the composition to set the hair or fur is an ionic, water-soluble compound, which is substantially non-oxidizing to the products of keratin reduction and which reforms substantially all the keratin disulfide bonds, while substantially avoiding precipitation. The kit comprising and facilitating the same method is included.
