A hair relaxant and process in which water-soluble disulfides are added to water-soluble mercaptans, used as reducing agents, to shift the equilibrium point of the relaxer toward the reactants sufficiently such that the relaxant will not cause damage to the hair. The ingredients are carried in a viscous creme base, and there is an absence of sulfite and bisulfite salts. This is followed by rinsing and the use of an oxidizing neutralizer. The process is carried out in the absence of added heat.

A process for inhibiting hair fibers from becoming frizzy, involving contacting the hair fibers with a composition containing: (a) at least one polyamine compound having at least two amino groups; (b) at least one anionic silicone; (c) optionally, at least one surfactant; and (d) optionally, at least one film-forming polymer, and wherein (a) is present in the composition in an amount sufficient to inhibit dyed hair fibers from losing their color, as well as inhibit hair fibers, in general, from ...
