Ducray Elution Gentle Balancing Shampoo is a gentle dermo-protective shampoo recommended as a follow-up to anti-dandruff treatments, which may weaken or damage the hair. This well-tolerated formula gently cleanses the scalp and reduces the risk of recurring dandruff thanks to its very light cleansing base combined with soothing active ingredients such as zinc gluconate and vitamin B5. The scalp is fortified and the hair is volumized, according to 94% of clinical trial volunteers.
