A process for the oxidation dyeing of keratin fibers, comprising,

• applying to the fibers at least one dye composition comprising,
• at least one first oxidation base chosen from 4,5-diaminopyrazole oxidation bases of formula (I) and addition salts thereof:
• wherein R1 is chosen from C1-C6 alkyl radicals substituted with least one radical OR, wherein R is chosen from C1-C6 alkyl radicals;
• at least one second oxidation base chosen from para-phenylenediamine derivatives of formula (II) and addition salts thereof:
• wherein:
• Z represents the atoms required to form a 3- to 8-membered saturated ring, wherein the atoms are optionally chosen from carbon and nitrogen atoms, and the ring may optionally be substituted;
• R2 is chosen from hydrogen, chlorine, and bromine atoms;
• linear and branched, saturated and unsaturated C1-C7 hydrocarbon-based chains, wherein at least one of the carbon atoms may be replaced with at least one entity chosen from oxygen, nitrogen, and sulphur atoms and an SO2 group, and wherein the carbon atoms may, independently of each other, be substituted with at least one halogen atom;
• provided that the radical R2 does not comprise a peroxide bond, a diazo radical, a nitro radical, or a nitroso radical;
• and
• at least one coupler and
• developing a color with at least one oxidizing agent.
