Vichy Dercos Anti-Dandruff shampoo for dry hair is a groundbreaking formula, based on the microbiome technology with Selenium DS, that eliminates 100% visible dandruff from the first application, while calming itchiness and discomfort. Its 6-week anti-relapse action controls fungus and bacteria growth by rebalancing the scalp microbiome and restoring the skin’s natural barrier function. The results are clear; with dandruff recurrence prevented even six weeks after the treatment has stopped. The scalp is left feeling soothed and cleansed.
