The color creme is formulated with Pro-Keratin complex that protects as it colors. This hair dye kit is available in a color palette ranging from Ash Blonde to Chocolate Brown to Jet Black. Absolutely gorgeous at home hair color. No permanent hair color protects better or covers grays better (compared to each leading competitor's top selling brand).
