Methods for preparing hair relaxer compositions which comprise a lithium salt and an alkaline earth hydroxide, wherein the lithium salt is in molar excess to the alkaline earth hydroxide. Compositions, kits containing the compositions, and methods for using the compositions are also disclosed.

A conditioning activator for a no-lye hair relaxer and a conditioning hair relaxer system includes a conditioning agent which is a water-soluble cationic compound. In a preferred embodiment the cationic conditioning agent is a cationic polymer. Also disclosed are methods for preparing phase-stable no-lye cream bases suitable for conditioning hair relaxer systems.

Provided is a novel composition for use in hair relaxing. The composition contains a quaternary ammonium hydroxide and a cosmetic base.

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 ha...

A composition for lanthionizing keratin fibers comprising at least one multivalent metal hydroxide and at least one cation exchange composition. The invention is also drawn to a method for lanthionizing keratin fibers to achieve relaxation of the keratinous fibers.

The present invention provides a composition for lanthionizing keratin fibers comprising at least one multivalent metal hydroxide and at least one complexing agent effective for dissociating said at least one multivalent metal hydroxide in sufficient quantity to effect lanthionization of said keratin fibers. In one embodiment, the complex that is formed between the complexing agent and a metal ion from the multivalent metal hydroxide is soluble in water. The invention is also drawn to a method f...
