<p>Composition for dyeing human keratinous fibres, contains at least one thickener and at least one special aromatic-heterocyclic dye in a cosmetically-acceptable medium. Dyeing composition (DC) for human keratin materials (e.g. hair) containing, in a cosmetically-acceptable medium, at least one thickener and at least one dye of formula (I) or (II). D : S, O, Se, B, NH or NR; R : (L) z-M; L : -CH 2CH = CH-, -CH 2-CC-, -CH 2C 6H 4-, -CH 2-thienyl- or -(CH 2) p-; z : 0 or 1; p : 1-4; M : halogen, 1-4C alkyl, alkoxy or hydroxyalkyl, NR 1R 2, -(1-4Calkyl)-NR 1R 2, -CONH 2, -COOY 91>, -COO(1-4C alkyl), CN, a cationic group, -SO 3Y 91>, -(1-4C alkyl)-SO 3Y 91>, or optionally substituted aryl or heteroaryl with 5-15 ring atoms; R 1, R 21-4C alkyl, alkoxy, hydroxy- or amino-alkyl; Y 91>H, Na or N(R 91>) 4 +>; R 91>H or 1-2C alkyl; A, B : N, NH, N = O or CR 3(not both NH simultaneously); R 3H, halogen, OH, CN, -SO 3Y 91>, 1-4C alkyl or (hetero)aryl (as above); E : N, CH or a carbon atom attached to one of the groups listed for M; G : CR 4or N +>-R 5; R 4as for M; R 51-4C alkyl, 2-4C alkenyl or (hetero)aryl as above; J, K : H, halogen, OH, CN, -SO 3Y 91>, 1-4C alkyl or -(Q) y-T; Q : -CH 2CH = CH-, -CH 2CC-, -CH 2C 6H 4- or -CH 2-C 4H 2S-; y : 0 or 1; T : aryl or heteroaryl with 5-18 ring members (condensed or not), optionally substituted with groups as listed for M; if y : 0 and E or G is a carbon atom, T plus E or G and the carbon carrying T may form an optionally substituted 5- or 6-membered ring; n : 0-5; U, V : H, halogen, OH, CN, -SO 3Y 91>, 1-4C alkyl or 5- to 15-membered (hetero)aryl; q : 1 or 2; if q : 2, X = -(CH=CHCH 2) a-, -(CH 2CH 2CH 2) a- or formula (a) and (b); R 6-R 9H, halogen, OH, CN, -SO 3Y 91>or 1-4C alkyl; a : 1-5; r : 0-5; s : 1-5; A : cosmetically-acceptable counter-ion(s) for electrical neutrality. Independent claims are also included for (1) a method (M1) for dyeing human keratinous fibres by applying DC until the required color is obtained, possibly rinsing, possibly shampooing and rinsing, and then drying (2) a method (M2) for dyeing human fibres, especially hair, by applying DC as above without a final rinse (3) a method (M3) for dyeing the skin by applying DC and then drying or leaving it to dry (4) a multi-compartment device for dyeing human fibres, comprising at least one compartment containing DC and at least one other compartment containing a composition with an oxidising agent.
