K18 Biomimetic Hairscience Leave-In Molecular Repair Hair Mask

Transform damaged hair with the original K18 Biomimetic Hairscience Leave-In Molecular Repair Hair Mask. Powered by the patented K18PEPTIDE™, this clinical hair treatment works deep within the inner layers of the hair to reconnect broken polypeptide chains. In just 4 minutes, it reverses damage caused by bleach, color treatments, chemical services, and heat styling, restoring strength, smoothness, and bounce.

​Key Benefits:

• ​Molecular Repair: Reconnects broken keratin bonds to permanently fix damage rather than just masking it.
• ​Clinically Proven: Restores hair to up to 91% original strength and 94% original elasticity in 4 minutes.
• ​Lightweight Formula: Leaves hair soft, smooth, and full of natural movement without heavy buildup.
• ​Universal Application: Effective on all hair types, textures, and degrees of damage.

​How to Use:

1. ​Shampoo Only: Wash your hair with shampoo. Do not apply conditioner.
2. ​Towel Dry: Gently towel-dry hair until damp.
3. ​Apply: Start with 1 pump and work thoroughly from ends to roots. Add more as needed depending on hair length and density (a little goes a long way).
4. ​Wait 4 Minutes: Leave it in for 4 minutes to let the peptide activate.
5. ​Style: Do not rinse. Style your hair as you normally would.
