Abstract: Composition comprises at least one direct dye having a disulfide, thiol or protected thiol functional group (I) or its salt with an organic or inorganic acid, or its optical or geometric isomers, tautomers and solvates, such as hydrates, at least one thickening organic polymer, at least one (poly)ethoxylated fatty alcohol and/or at least one nonionic surfactant, at least one alkaline agent, preferably comprising at least one amino group, and at least one reducing agent. Composition comprises at least one direct dye having a disulfide, thiol or protected thiol functional group of formula (A-(X) p-C sat-S-U1) (I) or its salt with an organic or inorganic acid, or its optical or geometric isomers, tautomers and solvates, such as hydrates, at least one thickening organic polymer, at least one (poly)ethoxylated fatty alcohol and/or at least one nonionic surfactant, at least one alkaline agent, preferably comprising at least one amino group, and at least one reducing agent. U1 : (-S-C1 sat-(X1) p1-A1) or Y1; A, A1 : radical comprising at least one quaternized cationic chromophore or at least one chromophore carrying a quaternized or quaternizable cationic group; Y1 : H or protective group for the thiol functional group; X, X1 : optionally saturated and linear or branched divalent 1-30C hydrocarbon chain which is optionally interrupted and/or optionally terminated at one or both of its ends by one or more divalent groups comprising -N(R)-, -N +>(R)(R)-, -O-, -S-, -CO- or -SO 2- with R; R : H, 1-4C alkyl, hydroxyalkyl or aminoalkyl, and a fused or nonfused, optionally saturated and aromatic or non-aromatic (hetero)cyclic radical which optionally comprises one or more heteroatoms and which is optionally substituted; C sat, C1 satlinear or branched 1-18C alkylene chain which is optionally substituted and optionally cyclic; and p, p1 : 0 or 1. Independent claims are included for: (1) dyeing and lightening keratinous fibers, preferably dark keratinous fibers with a height of tone of = 6, preferably = 4, comprising applying the composition and optionally at least one chemical oxidizing agent, which are applied either together to the fibers or separately, and compounds comprising 1-[(E)-2-[1-[6-[6-[2-[(E)-2-(4-dimethylaminophenyl)vinyl]pyridin-1-ium-1-yl]hexyldisulfanyl]hexyl]pyridin-1-ium-2-yl]vinyl]-N,N-dimethyl-pyridin-4-amine chloride, 3,3'-(2,2'-(2,2'-disulfanediylbis(ethane-2,1-diyl))bis(1,3-dioxo-2,3-dihydro-1H-benzo[de]isoquinoline-6,2-diyl))bis(azanediyl)bis(N,N,N-trimethylpropan-1-aminium)chloride, 2,2'-(2,2'-disulfanediylbis(ethane-2,1-diyl))bis(6-(3-(dimethylamino)propylamino)-1H-benzo[de]isoquinoline-1,3(2H)-dione) salt, and [4-[(E)-2-[4-(bis(2-hydroxyethyl)amino)phenyl]vinyl]phenyl]-[3-[3-[3-[3-[4-[(E)-2-[4-(bis(2-hydroxyethyl)amino) phenyl]vinyl]pyridin-1-ium-1-yl]propylamino]-3-oxo-propyl]disulfanylpropanoylamino]propyl]ammonium salt, preferably fluorescent dyes, to the keratinous fibers; and (2) a multicompartment device or kit, comprising a first compartment including a dyeing composition comprising the composition containing the direct dye, a second compartment including the reducing agent and optionally a third compartment, which comprises at least one chemical oxidizing agent.
