The present invention relates to a process for treating keratin fibers, in particular hair, comprising the steps of: applying onto the keratin fibers a composition comprising at least 0.01% by weight, relative to the total weight of the composition, of one or more synthetic direct dyes; placing the keratin fibers in an occlusive space; and heating the keratin fibers to from 50 to 250 °C. The present invention can provide a new coloring process for keratin fibers, such as hair, based on direct coloring(s) which can provide the keratin fibers with intense color with good level of color coverage, resistance to external factors or agents such as a shampoo, and only little damage, and which can provide the skin or scalp with less stains. |
