Vichy Dercos Kera-Solutions Restoring 2 Minute Mask is an easy to apply mask specifically formulated to protect and repair the hair fiber in just 2 minutes. As a result of external factors such as mechanical, chemical, thermal and UV aggressions, 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 to better respond to all situations. Given that, the Dercos Kera-Solutions mask is formulated with a concentration of Pro-Keratin Complex that is ideal to protect and repair the hair fiber. Additionally, it contains Panthenol which makes the hair softer, more elastic and easier to comb. In fact, studies demonstrate that when in combination with the serum and the shampoo this mask reduces capillary damage by 60%.
