Abstract
A method of setting hair which comprises treating the hair with an aqueous solution of a metal S-thiosulphato-derivative, and curing the derivative. The hair is treated at temperatures of from 15.degree.-60.degree. C. with aqueous solutions containing Bunte salt derivatives, covered with impermeable material, and left to react at from 20.degree.-60.degree. C. before finally rinsing off with water. The permanent setting is as good as with conventional thioglycollate compounds, but the noxious smells associated with the latter are absent.
