How to apply
Step 1. After cleansing, apply to your hands and onto hair from mid-lengths to ends.
Step 2. Comb through to ensure even application.
Step 3. Leave in for at least 5 minutes before rinsing.
Sam's Pro Tip is, Pop a shower cap over your treatment mask. The steam from the shower will open up your strands, helping the mask to penetrate your hair cuticle. To be used weekly or as frequently as desired alongside your Hair by Sam McKnight Cleanser.
