What it is: A restorative, sulfate-free shampoo that transforms severely damaged hair, intensely nourishing and repairing each strand. What it does: This deeply reparative shampoo is formulated with Strand-Building Proteins, which reconstruct each individual strand of hair from the inside out to rebuild and resurface hair, leaving strands strong, healthy, smooth, shiny and fully restored. What it is formulated WITHOUT:- Parabens- Sulfates - Phthalates What else you need to know: Strand-Building Proteins target damage at the microscopic level, working to repair each individual strand of hair. Delivering essential nutrients to the hair’s interior cortex, it nourishes and strengthens strands and fills in gaps and tears in the damaged cuticle, reconstructing this protective layer to ensure that nutrients do not escape. It also cements the newly constructed, exterior cuticle to the interior cortex, ensuring that the scales of the hair lay flat. Additionally, it seals and reinforces the cuticle layer with a defensive shield that strengthens the strand to increase resistance to breakage while infusing hair with vital antioxidants to help prevent free radical penetration and other damage from occurring. The result is stronger, smoother, softer, and shinier strands fully restored to their healthy, pre-damaged state.
