ABSTRACT:
A highly effective, ammonia-free, permanent waving lotion is attained by employing one a reducing agent consisting of a thiol compound or mercaptan in combination with an alkalizing agent consisting of an alkanolamine and an alkali metal hydroxide. In accordance with this invention, the reducing agent is employed either independently as 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 5.5 and 10.0. By employing this invention, long lasting permanently waved hair is attained with substantially less malodor being produced, thereby providing increased comfort to the stylist and the person who undergoes permanent waving.
