Collection: Vichy

Vichy thermal water is sourced from Vichy, France — a region with naturally occurring mineralised springs used in therapeutic spas since Roman times. The water naturally contains 15 minerals (including selenium, magnesium, calcium, bicarbonate) with documented skin-soothing, barrier-supporting and antioxidant benefits. Every Vichy product is built around this thermal water base, making the line particularly trusted for sensitive, reactive and compromised skin and scalp. The Dercos haircare line uses Vichy thermal water alongside targeted actives to address specific scalp concerns.

The Dercos Anti-Dandruff Sensitive Scalp Shampoo uses selenium DS — a clinically-studied antifungal active that targets Malassezia (the yeast responsible for dandruff) — alongside Vichy thermal water for calming sensitivity. The formula is sulfate-free and gentle enough for daily use, unlike harsher prescription anti-dandruff shampoos. Use 2–3 times per week as your regular shampoo: massage into the scalp, leave for 2–3 minutes (this contact time is critical for the active to work), then rinse thoroughly. Visible reduction in flaking and itching within 2–4 weeks.

Aminexil is a hair-strengthening molecule developed by L'Oréal research that targets hair loss by preventing the stiffening of the collagen around hair follicles — a process that contributes to hair shedding and thinning. Topical Aminexil has been shown in clinical studies to reduce hair shedding over 6 weeks of consistent use. The Dercos Energising Shampoo uses Aminexil alongside Vichy thermal water to support stronger, fuller-looking hair. For severe hair loss, combine with the Vichy Dercos Aminexil ampoule treatment (sold separately) for maximum benefit.

Yes — Vichy is one of France's flagship pharmacy skincare brands, alongside La Roche-Posay (also owned by L'Oréal), Avène, Bioderma, and Embryolisse. French pharmacy brands are known for clinical, no-nonsense formulations developed by dermatologists, available widely in pharmacies across France. Vichy specifically positions around mineralised thermal water and dermatologist-tested skin and haircare. The brand is widely trusted by dermatologists for sensitive, reactive, dandruff-prone and shedding-prone scalp issues.

Vichy and Korean haircare brands (KUNDAL, MOEV, Pyunkang Yul, Mielle) represent two different approaches. Vichy is dermatologist-clinical — focused on targeted treatment of medical-style scalp issues like dandruff, hair loss and sensitivity, with minimal fragrance and ingredient-led formulations. K-beauty haircare is often more sensory and trend-driven — focused on viral fragrances, scalp wellness, and innovative hero ingredients (caffeine, rosemary, Annurca apple, PDRN). Many users combine: Vichy for clinical scalp treatment, K-beauty for daily styling and fragrance.
