Patent ID: 7273058

Claim:
A method for simultaneously dyeing and permanent shaping of hair, said method comprising the steps of: a) dividing the hair into individual strands and winding the strands on curlers; b) immediately prior to application on the hair wound on the curlers in step a), mixing a hair shaping component (A) with a dye component (B) in a weight ratio of said dye component (B) to said shaping component (A) of about 1:1 to 1:10 to form a dyeing and shaping composition, wherein said hair shaping component (A) contains from 6 to 15 percent by weight of a keratin-reducing substance and said dye component (B) contains from 0.5 to 30 percent by weight of at least one dye compound and an amount of said keratin-reducing substance, as needed, so that said dyeing and shaping composition contains from 5 to about 18 percent by weight of said keratin-reducing substance; c) treating the hair wound on the curlers in step a) with said dyeing and shaping composition; d) then allowing the dyeing and shaping composition to act on the hair for an acting time sufficient for the permanent shaping of the hair amounting to from 3 to 30 minutes; e) after the allowing of step d), treating the hair with a fixing composition without applying an intervening acidic rinse to the hair and without applying a pre-fixing composition to the hair after the step d) and before the treating of the hair with the fixing composition; f) then allowing the fixing composition to act on the hair from 1 to 40 minutes; and subsequently g) rinsing the hair; wherein the dye component (B) contains at least one oxidative coupler compound and at least one oxidative dyestuff as oxidation dye precursor compounds, and said at least one oxidative dyestuff is selected from the group consisting of 4,5-diamino-1-(2-hydroxyethyl)-1H-pyrazole, 4,5-diamino-1 -(1-methylethyl)-1H-pyrazole, 4,5-diamino-1-[(4-methylphenyl)methyl]-1 H-pyrazole, 4,5-diamino-1-[(4-chlorophenyl)methyl]-1H-pyrazole, 4,5-diamino-1-methylpyrazole, 2-amino-6-methylphenol, 2-amino-5-methyl phenol and p-aminophenol derivatives of formula (I): wherein R 1 represents H, —OH 3 , —CH 2 CH 3 , —CH 2 OH, —CH 2 CH 2 OH, —CH 2 NH 2 , —CH 2 NHCH 2 CH 2 OH or —CH 2 OCH 3 and R 2 and R 3 , independently of each other, each represent H, —CH 3 , —CH 2 CH 3 , —CH 2 OH, —CH 2 CH 2 OH or —CH 2 CH 2 CH 2 OH, with the proviso that at least one of said R 1 , R 2 and R 3 is not H.
