What is Selenium Sulfide?

Selenium Sulfide is a powerful antifungal compound commonly used in dermatology to treat dandruff and seborrheic dermatitis. Notably helping to control flaking and reduce itchiness, Selenium Sulfide works by slowing the overproduction of skin cells and decreasing the presence of Malassezia, a yeast-like fungus that can disrupt the scalp's microbiome and contribute to visible dandruff.

Available in shampoos and scalp treatments, Selenium Sulfide can provide both immediate relief and ongoing protection against recurrence. Vichy incorporates this ingredient into our Dercos hair care formulas to support a healthy scalp environment without compromising gentleness, even on sensitive skin.
