L'Orýýal Paris Colorist Washout allows you to experience a long-lasting temporary coloring with ultra-visible shades and fast results. The color gradually fades, shampooing after shampooing, returning to the original shade or effect, shadows or strands. Long-lasting colors stay on the hair 10-20 shampoos. The color can last longer, depending on the porosity of the hair. The end result depends on the shade on which the product is applied.
