<p>Use of a composition (A) comprising furan-2-one compounds (I) or their salts, one or more direct dyes and/or oxidation dyes in a method for dyeing human keratin fibers, is claimed. Use of a composition (A) comprising furan-2-one compounds of formula (I) or their salts, one or more direct dyes and/or oxidation dyes in a method for dyeing human keratin fibers, is claimed. Either R1-R4 : alkyl, 1-30C alkenyl (both optionally substituted and interrupted by one or more oxygen atoms) or H (preferred); or R1R2 : a heteroaryl ring. Independent claims are included for: (1) the composition (A) comprising: one or more oxidation dyes; direct dyes; and (I) in a medium; (2) method for dyeing human keratin fibers, comprising applying the composition (A) to the fibers; and (3) multi-compartment device comprising: first compartment having a composition (A), and another composition comprising one or more oxidizing agents.
