The invention relates to a hair treatment agent which exhibits clear hair care effects despite a reduced total quantity of cationic active substances, containing at least one QAV according to the formula (I) in which n represents a whole number from 10 to 24 and X- represents an anion at least one QAV according to the formula (II) in which m represents a whole number from 10 to 24 and X- represents an anion at least one QAV of the formula (III) in which R and R each represent a saturated or unsaturated linear or branched hydrocarbon group with a chain length of 18 to 30 carbon atoms independently of each other and X- represents an anion and at least one cationic copolymer containing monomers of the formula (IV) and monomers of the formula (V) in which R1 to R9 represent hydrogen or C1-4 alkyl such as methyl, ethyl, propyl, isopropyl, butyl, isobutyl, or tert-butyl independently of one another with the proviso that at least one of the groups R6, R7, R8, or R9 represents C1-4 alkyl, n represents a whole number from 1 to 8, and A- represents a physiologically acceptable anion.
