Abstract
Abstract A preparation for dyeing and setting hair in a permanent wave comprising a first agent including L-cysteine monohydrochloride monohydrate solution and/or thioglycolic acid, P-phenylenediamine or O-phenylenediamine, resorcinol, anti-oxidation agent heavy metal ion sealing agent and mono-ethanolamine, and a second agent containing hydrogen peroxide. The preparation allows dyeing and setting of hair in a single operation over a short period.
