    Abstract: The invention relates to the use of reactive dyes for dyeing hair. Said reactive dyes are of formula (I), wherein a represents 1 or 2, b represents 0 or 1, Y represents vinyl or a radical of formula C2H4Q, Q being a group which can be split off in alkaline reaction conditions, L represents a direct bond or a binding link of formula CO-NH-M which can be interrupted by 1 or 2 non-adjacent oxygen atoms, imino or C1-C4 alkylimino groups, M being C2-C6 alkylene, A represents hydroxysulfonyl or a radical of formula SO2Y, A represents hydrogen, hydroxysulfonyl, methoxy, chlorine, bromine or carboxyl, W represents 1) the radical of a coupling constituent, of a monoazo dye or additionally, when b=0, of a disazo dye, which can carry other reactive groups, or 2) the radical of a chromophore which optionally has other reactive groups, and L and L each represent a binding link. The invention also represents a method for dyeing hair, and cosmetic preparations for dyeing hair.
