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