Zusammenfassung: | The present invention concerns a composition for the permanent shaping of human hair used both for the permanent waving of human hair with an excellent waving effect as well as for the straightening of either naturally or chemically curled hair comprising a diamide compound. Accordingly, the present invention is on a composition for permanent shaping hair based on at least one reducing agent and a compound comprising at least two amide (diamide) groups in its molecule and at least one cationic polymer. Preferred diamide compounds are according to the general structure
wherein R 1 is a linear or branched, saturated or unsaturated alkyl chain with 1 to 12 C atoms which may be substituted with hydroxy and/or alkoxy groups, R 2 is linear or branched alkyl chain with 1 to 5 C atoms, and R 3 linear or branched, saturated or unsaturated alkyl chain with 1 to 22 C atoms. |
