A subject of the invention is the use of i) hydroxyindol(in)e derivative(s) glycosylated on at least one hydroxyl group, in the presence of at least ii) one enzyme with glycosidase activity, in particular beta-glycosidase activity, more particularly glucosidase activity and even more particularly beta-glucosidase activity, for treating keratin fibres, in particular dyeing human keratin fibres such as the hair, preferably dyeing said fibres. A subject of the invention is also a process for treating keratin fibres using i), ii) and a kit comprising the ingredients i) and ii). The process according to the invention has the advantage of dyeing human keratin fibres, with powerful or chromatic dyeing results that are resistant to washing, perspiration, sebum andlight, and that are moreover long-lasting, without impairing said fibres. Furthermore, the colourations obtained from the process give uniform colours from the root to the tip of a fibre (low colouration selectivity). In addition, the compositions comprising the i) hydroxyindol(in)e derivative(s) glycosylated on at least one of the hydroxyl groups degrade very little in air and remain stable with respect to storage.
