Abstract:
The present invention relates to a process for treating hair, especially human hair, wherein the hair is bleached and dyed in a subsequent order with compositions providing improved and milder bleaching and dyeing of hair. The inventors of the present invention have unexpectedly found out that when commonly used bleaching compositions and oxidative dyeing compositions are mixed with another composition comprising predominantly carboxylic acids, the bleaching and dyeing effects of the compositions are improved, homogeneous bleaching and dyeing of hair fibers is achieved and natural cosmetic properties of hair is maintained.

Claim (Index 1):
A process for treating hair, especially human hair, comprising the following steps:\n a. hair is applied an aqueous composition obtained from mixing two compositions A and B, wherein the composition A is an anhydrous composition comprising one or more persalts and one or more alkalizing agents, wherein the composition B is an aqueous composition comprising one or more oxidizing agents, and has a pH in the range of 1.5 to 5, wherein the mixed composition consisting of compositions A and B has an alkaline pH in the range from 8 to 11, b. the composition is left on the hair for a period of 1 min to 45 min, c. the hair is rinsed off and towel dried, d. Optionally the hair is dried, e. Hair is applied another aqueous composition obtained from mixing the two compositions C and B wherein the composition C is an aqueous composition comprising one or more hair dyes and one or more alkalizing agents and has an alkaline pH in the range of 7.5 to 12, f. left on the hair for a period of 1 to 45 min, g. rinsed off from the hair, and h. hair is optionally washed with a cleansing composition and dried, wherein the composition(s) in step(s) a and/or e is (are) mixed with a composition D immediately before application onto hair for obtaining ready-to-use composition(s), wherein the composition D comprises i. one or more carboxylic acids and/or their salts having three or more carboxyl groups, and ii. one or more organic additional acids and/or their salts having one or two carboxyl groups, wherein the composition D comprises the acids of i) and ii) and/or their salts at a total concentration of 10% to 100% by weight calculated to the total of composition D, wherein the ready-to-use compositions in steps a and d have a pH in the range from 6.5 to 11 and comprise the acids and/or their salts at a total concentration in the range from 1% to 10% by weight calculated to the total of each of the ready to use compositions.
