La Roche Posay Kerium Doux Extrême Gel Shampoo - 400 ml

La Roche-Posay Kerium Doux Extrême Gel Shampoo is a 400 ml shampoo formulated for sensitive scalps that need frequent washing. The distinction from ordinary shampoo is the cleansing base: standard formulas use harsh sulphates that strip the scalp's protective lipids, so washing often leaves the scalp tighter, itchier and more irritated than before — a cycle many people mistake for dandruff and try to fix with medicated shampoos, which makes matters worse. This uses an extremely mild base that cleanses effectively while preserving the scalp's moisture balance, making it suitable for daily or near-daily use without cumulative irritation. The scalp feels calm and comfortable rather than tight, and hair is left clean, soft and manageable without residue. Formulated with La Roche-Posay thermal spring water and suitable for reactive, itchy and eczema-prone scalps, including alongside dermatological treatment. Apply to wet hair, massage gently into the scalp, then rinse thoroughly. The large bottle suits frequent washing.
