Recommended before each colouring or bleaching process, Huile dAlès ensures effective protection of the hair fibre and scalp. SIMPLE APPLICATION: dry, unwashed hair. - Case 1: Hair that has never been colored: Apply the mixture to the roots and then spread the excess product over the rest of your hair. Leave on for 30 minutes. - Case 2: Hair that has already been colored, root touch-up: Apply the mixture to the roots only, leave on for 20 minutes. Then spread the excess product from the mid-lengths to the ends and leave on for 10 minutes. Once the rest time has passed, pour warm water over your hair and then rinse thoroughly with warm water until the water runs clear. Jujube bark extract and EpalineTM have been selected for their soothing and moisturizing action and their anti-irritation and anti-itch properties: EpalineTM envelops the scalp in a protective veil, and jujube bark extract soothes discomfort. The duo of precious oils, monoi and jojoba, works synergistically to plump the hair fiber with its treatment, deeply nourish it, and provide exceptional shine.
