This innovative hair mask works like a bandage, covering hair with a layer of protection, preventing damage while it allows hair to heal and repair. The formula is enriched with breakthrough ingredients such as Fibra-Kap, an ingredient that effectively envelopes each strand of hair to protect it from external aggressors, environmental factors, heat, humidity and day-to-day breakage. The formula also includes Seve de Resurrection, a deeply nourishing treatment ingredient that rehabilitates dry and damaged hair to restore shininess, silkiness, smoothness and strength. These ingredients work together to leave hair looking soft and healthy. Products from Kérastase are created by a team of hair care experts, scientists and stylists to deliver healthy and manageable hair. The gentle and effective formulas are easy to use, making them a great way to achieve salon quality results at home.
