Abstract:
The present invention relates to a hair dyeing process for improved and milder dyeing of hair, especially human hair. The ready-to-use dyeing composition comprises carboxylic acids in addition to dyeing agents and oxidizing agents in order to improve dyeing efficiency with less loss of natural hair properties.

Claim (Index 1):
A process for dyeing hair, especially human hair, wherein the compositions A, B, and C, being kept separately before application onto hair, and are mixed immediately before application onto hair at a weight ratio of A:B:C in the range from 1:2:0.1 to 1:1:1, to obtain a ready-to-use composition,\n wherein the composition A 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, wherein the composition B is an aqueous composition comprising one or more oxidizing agents, preferably hydrogen peroxide, and has a pH in the range of 1.5 to 5, wherein the composition C comprises i) one or more carboxylic acids and/or their salts having three or more carboxyl groups, and ii) one or more additional organic acid and/or their salts having one or two carboxyl groups, wherein the composition C 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 the composition C, wherein the ready-to-use composition has an alkaline pH in the range of 8 to 11 and comprises the acids and/or their salts at a total concentration in the range from 1% to 10% by weight calculated to the total of the ready-to-use composition, wherein the ready-to-use composition is applied onto hair and left on the hair for 1 to 45 min, then rinsed off from hair and optionally the hair is shampooed and dried.
