A hair relaxing system, activator and methods of use and preparation are disclosed. The system includes a first package containing a substantially water-free activator that includes a hydrolyzable organic base having a PK.sub.a value of at least about 12 present in free base form in an amount sufficient to relax hair dissolved in an organic solvent that is immiscible with petrolatum. The second package of the system contains water and may also contain oleaginous materials and emulsifiers. Admixture of the first and second packages provides a relaxer composition that has a pH value of at least 12 and contains at least about 20 weight percent water.
A two-package pretreatment and hair relaxer system comprising: a first package comprising a neutral pretreatment composition containing a polyampholyte terpolymer having a weight average molecular weight of from about 4 thousand to 4 million, of the formula: ##STR1## wherein said polyampholyte terpolymer is present in amounts sufficient to coat hair and prevent excessive brittleness and roughness to relaxed hair; and a second package containing calcium hydroxide in amounts sufficient to relax hair and a polyampholyte terpolymer having a weight average molecular weight of from about 4 thousand to 4 million, of the formula: ##STR2## in amounts sufficient to impart significant amounts of moisture, softness and sheen to relaxed hair.
A composition and process for setting hair comprises impregnating the hair with a composition containing in solution in a cosmetic vehicle at least one water-soluble polymer containing at least 5% of units having a primary amide function, a crosslinking agent and an acid catalyst. The hair is then placed on hair-setting rollers and dried by means of an external heat source. The hair rollers are then removed.
A highly alkaline, no-base hair relaxer cream composition is disclosed which is phase-stable on ageing. A composition of this invention is a highly alkaline cosmetic cream base that may be use directly as a no-base hair relaxer or as a no-lye cream that may be converted for use as a no-base, no-lye hair relaxer by admixture with an aqueous activator solution. A method for preparing such a phase-stable no-base hair relaxer cream composition is also disclosed.
