Abstract: The present invention is related to a process for colouring and permanent shaping keratin fibres especially human hair in a single process. The novel process for colouring and permanently shaping keratin fibres especially human hair according to the present invention includes the following steps: a—an aqueous oxidative colouring composition based on at least one oxidative dye precursor and optionally at least one coupling substance but not comprising any direct dye is mixed with a composition comprising at least one oxidizing agent and applied onto hair and rinsed off from hair with water after processing 5 to 45 min at a temperature of 20 to 45° C.

The novel process for colouring and permanently shaping keratin fibres especially human hair according to the present invention includes the following steps: a—an aqueous colouring composition based on at least one hair direct dye and not comprising any oxidative dye precursors and/or couplers is applied onto hair and rinsed off from hair with water after processing 1 to 45 min at a temperature of 20 to 45° C.

Abstract: The present invention concerns a composition for the permanent shaping of human hair comprising a copolymer of vinylpyrrolidone and quaternized vinylimidazole at a concentration in the range of 0.1 to 2.5% by weight calculated to total composition and process for permanent shaping human hair with the said compositions.

Abstract: The present innovation concerns a composition for the permanent shaping of human hair comprising at least one reducing agent at a concentration of above 2% by weight an aminated silicone compound at a concentration in the range of 0.1 to 2.5% by weight calculated to total composition and a copolymer of vinylpyrrolidone and quaternized vinylimidazole at a concentration in the range of 0.1 to 2.5% by weight calculated to total composition and process for permanent shaping human hair with the said compositions.
