L’Oréal Professionnel Scalp Advanced Anti-Oiliness Dermo-Purifier Shampoo is specifically formulated to address the needs of oily scalps. Enriched with 3% AHA, a water-soluble acid, this lightweight gel effectively cleanses the scalp and hair fibre by removing residue, sweat, and excess oil for a fresher, cleaner feel. The formula is free from colorants, silicones, sulfates, and alcohol, ensuring a gentle cleanse without stripping natural moisture. To use, apply evenly on wet scalp and hair, gently lather with fingertips without over-massaging to avoid stimulating sebum glands, and rinse thoroughly. For enhanced results, consider using the Scalp Advanced Anti-Oiliness 2-in-1 Deep Purifier Clay as a pre-shampoo treatment for extra unclogging and as a mask for additional purification.
