Oxidation hair dye composition and method of dyeing hair using same

The composition for oxidative dyeing of keratin fibers has a pH of from 6 to 9.5 and contains a developer/coupler combination, an oxygen-oxidoreductase/substrate system and a peroxidase. The coupler substance includes a substituted m-phenylenediamine of formula I STR1 wherein R1 is a C1 - to C6 -alkoxy group, an unsubstituted alkyl group having from one to six carbon atoms, a C1 - to C6 -alkyl group substituted with a hydroxy group, a halogen atom or a C1 - to C6 -alkoxy group; and R2, R3 are each, independently of each other, a hydrogen atom, another unsubstituted C1 - to C6 -alkyl group, an unsubstituted C1 - to C6 -ether group having at most two oxygen atoms, another C1 - to C6 -alkyl group substituted with a hydroxy group, a halogen atom or a C1 - to C6 -alkoxy group substituent or an ether group substituted with a hydroxy group, a halogen atom or a C1 - to C6 -alkoxy group, and S represents a hydrogen atom or a further alkyl group having from one to six carbon atoms, or a physiologically compatible salt of the m-phenylenediamine of the formula (I).

Process for preparing a hair dye or hair bleach composition; a composition for use in this process; and the use of said composition to dye or bleach hair

A process for preparing a hair dye or bleach composition which comprises mixing a gelifiable liquid vehicle with an oxidizing solution having dissolved therein an incompatible cationic polymer. The resulting gel is applied to the hair and after an appropriate contact time, the hair is rinsed.
