Method for simultaneously dyeing and permanent shaping of hair
First Claim
1. A method for simultaneously dyeing and permanent shaping of hair, said method comprising the steps of:
- a) immediately prior to application on the hair, mixing a hair shaping component (A) containing from 6 to 15 percent by weight of a keratin-reducing substance with a dye component (B) to form a dyeing and shaping composition;
b) treating the hair with the dyeing and shaping composition;
c) 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;
d) after the allowing of step c), applying to the hair an intervening acidic rinse having a pH of 2 to 6;
e) after the applying of the acidic rinse of step d), treating the hair with a 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)-1 H-pyrazole, 4,5-diamino-1-(1-methylethyl)-1H-pyrazole, 4,5-diamino-1-[(4-methyl-phenyl)methyl]-1H-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);

Abstract
The method for simultaneously dyeing and permanent shaping of hair includes dividing the hair into strands an winding the strands onto curlers: mixing a hair shaping component (A) containing from 6 to 15 percent by weight of a keratin-reducing substance with a dye component (B) to form a dyeing and shaping composition prior to application on the hair; treating the hair with the dyeing and shaping composition and then allowing it to act on the hair for an acting time sufficient for the permanent shaping; after that, treating the hair with a fixing composition; allowing the fixing composition to act on the hair from 1 to 40 minutes and then subsequently rinsing the hair. The dye component (B) contains at least one oxidative coupler compound and at least one oxidative dyestuff selected from a group consisting of certain 4,5-diamino-pyrazole derivatives and certain aminophenol derivatives.
