Cosmetic composition (A) for coloring keratin fibers, especially human hair, contains, in a medium, at least one hydroxyalkyl-substituted direct cationic dye (I) and at least one cosmetic adjuvant. Cosmetic composition (A) for coloring keratin fibers, especially human hair, contains, in a medium, at least one hydroxyalkyl-substituted direct cationic dye of formula (I), or its mesomeric forms, and at least one cosmetic adjuvant. A : N, NR9 or CR9; B : O, S, N or CR9, provided at least one of A and B is a heteroatom carrying a permanent cationic charge and electroneutrality is ensured by an external counterion, Y, and/or by substituents on the tricyclic nucleus; D : amino (optionally substituted by one or two 1-24C alkyl, optionally interrupted by by one or more heteroatoms and/or optionally substituted, and the N substituents may together complete a 5-12 membered ring, saturated, unsaturated or aromatic, and may themselves be substituted by carboxy and/or sulfonic acid) or amino substituted by 1 or 2 aryl, optionally substituted, and D is para to the carbon carrying A or B; z : 1-24C alkylene, optionally interrupted by one or more heteroatoms, and -N(zX)R2 is attached to the tricyclic nucleus; X : CR8R'8-OR1; R1hydrogen or 1-24C hydroxyalkyl; R8 and R'8hydrogen, 1-24C alkyl (optionally interrupted by one or more heteroatoms or carbonyl, and/or optionally substituted) or is hydroxyalkyl; R2as R8 or hydrogen; R3 to R7hydrogen, halo, 1-24C alkyl as R8, amino optionally substituted by 1 or 2 1-24C alkyl (as defined for R8) and the N substituents may form a 5-12 membered heterocycle, saturated, unsaturated or aromatic, optionally substituted by carboxy and/or sulfonic acid; R91-24C alkyl, optionally substituted, benzyl or aryl, optionally substituted by one or more of 1-24C alkyl or alkoxy, carboxy or sulfonic acid; proviso: when R2hydrogen, then one of D, R3 to R7 is disubstituted amino. Independent claims are also included for the following: (1) method for dyeing or brightening keratin fibers using (A) and (2) multicompartment kit containing (A), free of oxidizing agent, in one compartment and an oxidizing agent in a second compartment, with adjuvants in either compartment.
