Excellence Crème by L'Oreal Paris is a Triple Care Color routine that deeply cares for your hair and covers 100% of grays, even stubborn ones. The color creme is formulated with Pro-Keratine complex that protects as it colors. The caring after-color shampoo is formulated specifically to be used right after rinsing out your Excellence coloring mix. It delicately cleanses the scalp and hair of excess residue and smoothes the hair to reveal rich, radiant color. The caring deep conditioner provides up to 8-weeks of intensive care. This hair dye kit is available in 30 shades for 100% gray coverage on all hair types. No permanent hair color protects better or covers grays better (vs each leading competitor's top selling brand). Instructions vary by shade. For complete instructions, please refer to package insert located inside hair color box.
