Kerastase Volumifique Bain Volume Thickening Effect Shampoo (250ml) is a creamy, volumising shampoo which has a thickening effect on fine hair. Cleansing & conditioning lacklustre locks, it benefits from Kerastase's Amplifex System which contains Cationic Polymers to nourish weaker areas & reinforce the hair's internal structure. Equally effective on longer hair, it has a lightweight finish & gives a glossy finish for healthy-looking, thickened hair.
