Compositions and processes permanent shape human hair for the permanent waving of human hair with an excellent waving effect as well as for the straightening of curled hair. A composition for permanently shaping hair has at least one reducing agent or at least one oxidizing agent and a cross linked copolymer of vinylpyrrolidone, vinylimidazol, 3-methyl-1-vinylimidazolium chloride and methacrylic acid. A process for permanent shaping hair wherein a composition comprising at least one reducing agent is applied and rinsed off from hair after a processing time of 1 to 30 min and at a temperature of 20 to 45° C. and a composition comprising at least one oxidizing agent is applied and processed for 1 to 20 min at a temperature range of 20 to 45° C. and rinsed off from hair wherein at least one of the compositions has a cross linked copolymer.
A process for permanent shaping hair wherein the hair is optionally washed or wetted or shampooed and a reducing composition comprising at least one reducing agent is applied and rinsed off from the hair after a processing time of 1 to 30 min and at a temperature of 20 to 45° C. and an oxidizing composition comprising at least one oxidizing agent is applied and processed for 1 to 20 min at a temperature range of 20 to 45° C. and rinsed off from hair wherein at least one of the two compositions comprises a cross linked copolymer of vinylpyrrolidone, vinylimidazol, 3-methyl-1-vinylimidazolium chloride and methacrylic acid.
A composition for permanently shaping hair comprising at least one reducing agent at a concentration of 0.5 to 15% by weight calculated to total of the composition selected from thioglycolic acid, thiolactic acid as well as the salts thereof, cysteine or the hydrochloride thereof, homocysteine, cysteamine, N-acetyl cysteine, thioglycerol, ethanediol monothioglycolate, 1,2-propyleneglycolmonothioglycolate, 1,3-propanediol monothioglycolate or the isomer mixture resulting therefrom, 1,3-butanediol and 1,4-butanediol monothioglycolate and the isomer mixtures therefrom, polyethylene glycol, such as di-, tri- and tetraethyleneglycol monothioglycolates, glycerol monothiolactate and further thio acids and the esters thereof, as well as mixtures thereof and a cross linked copolymer of vinylpyrrolidone, vinylimidazol, 3-methyl-1-vinylimidazolium chloride and methacrylic acid.
A composition for permanently shaping hair comprising at least one oxidizing agent at a concentration of 0.1 to 5% by weight calculated to the total composition and selected from hydrogen peroxide and sodium bromate, and a cross linked copolymer of vinylpyrrolidone, vinylimidazol, 3-methyl-1-vinylimidazolium chloride and methacrylic acid.
