- Revives and softens even the most deeply-stressed or overworked hair and tames frizz. Light enough not to weigh down hair, but hydrating enough to tame frizz. Repairs and protects. Made with AHA structure complex: Lactic Acid – supports internal reconstruction, Stearoxypropyl Dimethylamine – evens out the hair surface, and Glycyl Glycine – improves manageability. For all hair types. Apply evenly to shampooed hair and leave on 3-5 minutes then rinse. Great to prep for blow-dry.
