Pro Tip
Work in 1-inch sections and ensure even distribution from roots to ends for consistent smoothing results throughout the hair.
1. After shampooing, towel-blot hair, detangle then part hair into 4 sections. 2. Wearing gloves, take 1-inch partings and apply 1-2 pumps of Smoothing Mousse at roots and comb through. DO NOT RINSE OR SHAMPOO. 3. After full head application is complete, cover with plastic cap and allow treatment to sit for 15 minutes. Note: A full head application should not exceed 2 oz. of product. Coat hair, but do not over saturate.
