Vichy Dercos Kera-Solutions Resurfacing Shampoo is a repairing shampoo specifically designed to care for the needs of damaged hair and also sensitive or weakened scalp. Due to external factors such as mechanical, chemical, thermal and UV aggressions, the scalp becomes sensitized and the hair becomes dry and suffers fiber damage. Because each area of the capillary fiber has different needs, Dercos Kera-Solutions has different concentrations of the Pro-Keratin Complex in each product. For this reason, it can better respond to the hair specific needs. Dercos Kera-Solutions shampoo is formulated with Pro-Keratin Complex and Allantoin. This combination makes this shampoo ideal to protect and repair the hair fiber but also soothe and soften the scalp. In fact, studies demonstrate that when in combination with the serum and the mask this shampoo reduces capillary damage by 60% and provides 3x more hair shine.
