Abstract
A highly effective permanent waving lotion is attained by employing one compound selected from the group consisting of glyceryl monothiopropionate, glyceryl thiolactate, and combinations of glyceryl monothiopropionate and glyceryl thiolactate as the sole reducing agent. In accordance with this invention, the reducing agent is employed either independently in an aqueous solution or in association with desired additives for imparting additional benefits to the permanently waved hair. Preferably, the reducing agents of the present invention are employed in a permanent waving lotion having a pH ranging between about 6.0 and 9.5. In this way, processing time is reduced and long lasting permanently waved hair is attained with substantially less malodor being produced.
