A deeply restorative, luxe leave-in treatment for coarse, porous, or severely damaged hair. This powerfully reparative leave-in treatment is formulated with strand-building proteins to help restructure strands, fill in gaps and tears in the cuticle, and strengthen the hair, protecting it from breakage and future damage. Transforming previously coarse hair, it significantly improves smoothness, texture, and manageability. How to use: Apply to freshly cleansed hair, focusing on the lengths. Blow dry as usual. Depending on severity of damage, use 1-3 times a week.
