KeratinFIXX Repair Shampoo provides an additional layer of protection while moisturizing every strand. The keratin complex in our keratin repair shampoo is easily absorbed by the hair cuticle, the structure that holds hair fibers together. Because factors such as excessive combing, coloring, and heat treatment can lift the overlapping scales of the hair cuticle, allowing undesirable substances to penetrate and damage the fibers. Our shampoo closes the cuticle flaps and softens its surface, protecting the core fibers from damage and making each strand smoother. Keratin also replenishes areas of the hair shaft with chipped cuticles to strengthen your hair. Our repair shampoo provides a moisture boost and preserves the scalp's natural oils, so you can enjoy beautiful, healthy hair.
