Chemical hair removers are currently available at retail. Chemical depilatory compositions are convenient because they destroy the hair more thoroughly than shaving, thereby reducing frequency of use, and without the risk of cuts or abrasions. Most chemical depilatory agents currently available employ thiols (ie mercaptans) as active depilatory agents, especially salts of thi...
