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 0.001% by weight, relative to the total weight of the composition, of one or more oxidative 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 oxidative coloring(s) which can provide the keratin fibers with more intense color, better level of color coverage, and resistance to external factors or agents such as a shampoo. |
