ABSTRACT:
A single formula, mild, alkaline permanent wave conditioning composition provides a strong, long lasting curl like an alkaline permanent wave composition but leaves the hair soft like an acid permanent wave composition while minimizing further damage to already damaged hair. The composition contains a water-soluble alkali salt of thioglycolic acid, such as ammonium thioglycolate in an amount of about 2% to about 22% by weight; a water-soluble alkaline dithiodiglycolate, such as diammonium dithiodiglycolate in an amount of about 0.1% to about 18% by weight; a hair softening and/or moisturizing agent, such as glycerine in an amount of about 0.1% to about 20% by weight; and sufficient additional alkali, if necessary, to bring the pH of the composition to about 7.5 to 8.7. This composition is easy to use and apply without damaging the hair while providing a strong, tight curl and leaving the hair unexpectedly soft. The composition can be lotion or water wrapped and can be used with or without heat. Unexpectedly, the composition is applied to any type of hair, regardless of structural damage to the hair, resulting in the same degree of curl tightness and softness.
