1. A hair coloring and/or bleaching composition comprising at least a first aqueous component (i) and a second aqueous component (ii) being mixed prior to application onto hair, wherein:
the first aqueous component (i) comprises, in a cosmetically acceptable carrier: one or more oxidizing agent(s), one or more fatty alcohols and a polyoxyethylene C12-C30 alkyl ether and
the second aqueous component (ii) comprises, in a cosmetically acceptable carrier: one or more alkalizing agent(s) selected from the group consisting of ammonia, its salts and mixtures thereof, one or more fatty alcohols and a polyoxyethylene C12-C30 alkyl ether,
and optionally one or more oxidative dyes or one or more direct dyes or a mixture of one or more oxidative dyes and one or more direct dyes,
wherein the second aqueous component (ii) comprises a mixture of a first and a second malodor suppressant, the first and the second malodor suppressant forming a malodor suppressant system in the hair coloring and/or bleaching composition,
wherein the mixture of first malodor suppressant and second malodor suppressant is equal weight percentages of isopropyl myristate and Galaxolide at a mixture concentration in the second aqueous component (ii) to provide a concentration of the mixture of isopropyl myristate and Galaxolide in the mixture of the first aqueous component (i) and the second aqueous component (ii) of to about 0.7 wt %; and,
wherein a mixture of the first and second aqueous components exhibits a decrease of the amount of gaseous ammonia released relative to the combination of first and second aqueous components without the first and second malodor suppressants.
