From the first use, the DERMO-TREATING shampoo eliminates dandruff and soothes itching sensations. It limits recurrence and rebalances the scalp as it is applied. At the heart of the formula, lactic acid (AHA) and salicylic acid (BHA) treat dandruff immediately and eliminate dead cells. Celery extract helps to permanently prevent the reappearance of dandruff thanks to its anti-recurrence action. Thanks to a rosemary extraction, the scalp is protected against external aggressions. Dermatologically tested on volunteers with moderate and persistent skin conditions. Silicone-free.
