Main highlights
- Works on All Hair Types: Because our hair treatment works at the innermost layer of the hair rather than only targeting the outer cuticle like many deep conditioning hair masks, it's effective on all strands, even coily and curly hair.
- How to Use: Shampoo, skip conditioner, and apply 1-3 pumps of the leave in hair mask to clean, towel-dried hair. Let sit for 4 minutes, do not rinse, then style as usual. Use for 4-6 consecutive washes, then as needed.
- How It Works: Patented K18PEPTIDE repairs hair at a molecular level to reverse damage from bleach, color, chemical services, and heat*. The biotech-developed peptide mimics and clicks into hair's keratin structure to reconnect polypeptide chains and disulfide bonds for strength along the length + width of hair.
- Boosts Strength + Smoothness: Helps improve texture, manageability, and bounce with a highly concentrated hair cream formula with detangling and softening benefits. Most see results after 2-3 uses.
- 4-Minute Molecular Hair Repair Treatment: A leave-in peptide hair mask designed to repair and reverse damage at the molecular level for stronger, smoother, more resilient hair in just 4 minutes.
