    • This invention refers to a composition for permanent waving of human hair, containing thioglycolic acid or the salts thereof, preferably the ammonium salt, and comprising two compositions which are kept separate until application, whereof a Composition (A) contains at least an amino acid hydrochloride and at least one polyol or the methyl and ethyl ethers thereof, preferably 1,2-propanediol in aqueous solution, having a pH-value of preferably between about 4.5 and 6.5, and a Composition (B) which is kept separate from said Composition (A) until use contains ammonium carbonate, ammonium hydrogen carbonate, and (or) ammonium carbamate as alkalizing agent(s), having a pH-value between about 8 and 9.5, and both compositions are mixed before application whereby a pH-value between about 7 and 8 is obtained. The compositions, which are kept separate, present outstanding stability; upon application after admixture optimal waving performance and, at the same time, gentle treatment of the hair is achieved.
