How to Apply for Best Results

Sprinkle a small amount onto dry, styled hair, focusing on thinning areas. Build gradually until desired coverage is achieved, then gently pat to set. For damp weather or sweat, lightly blot hair with a towel before applying.

Pro tip: Start light and build, less product creates a more natural finish.
