Composition for keratin fibers comprising a direct dye
The present invention relates to a composition for treating keratin fibers, preferably hair, comprising: (a) at least one direct dye; (b) at least one oil; (c) at least one polyol; and (d) water, wherein the amount of the (a) direct dye(s) in the composition is 0.01% by weight or more relative to the total weight of the composition, and the amount of the (b) oil(s) in the composition is 20% by weight or more, preferably 30% by weight or more, and more preferably 40% by weight or more, relative to the total weight of the composition, provided that the (b) oil comprises at least one silicone oil. The composition according to the present invention is stable and can be used for coloring keratin fibers, in particular for the maintenance of the color of the keratin fibers, while providing the keratin fibers with smoothness and alignment.
