Description

Introducing the K18 Leave-In Molecular Repair Hair Mask - a patented leave-in mask backed by 10 years of bioscience research designed to reconnect keratin chains that have been broken down due to chemical, mechanical, and environmental factors. Unlike other hair masks on the market, K18 works on a molecular level to reverse hair damage in just 4 minutes, leaving you with soft, smooth, strong hair that feels like new.

The secret to K18's effectiveness lies in the K18PEPTIDE™ - a biotech-developed peptide that mimics hair's structure to reverse damage by reconnecting polypeptide chains and disulfide bonds broken during bleach, colour, chemical services, and heat. Clinically proven to repair damage from all of these sources, K18 delivers immediate and lasting results to restore strength, softness, smoothness, and bounce to hair.

But that's not all - K18 is also pH-optimized to help minimize cuticle swelling and put hair proteins in their most resilient state. The cream format enables easy, lightweight application across all hair types, with detangling and softening benefits, and it's vegan, colour-safe, and cruelty-free. So whether you have fine, straight hair or thick, curly locks, K18 is the perfect choice for anyone looking to restore their hair's natural beauty and strength.

Say goodbye to damaged, dull hair and hello to healthy, vibrant locks with the K18 Leave-In Molecular Repair Hair Mask. With its groundbreaking formula and proven results, it's the ultimate choice for anyone looking to take their hair repair to the next level.

Directions

How To Use K18 Leave-In Molecular Repair Hair Mask

Shampoo, don't condition. Towels should be dried thoroughly. Begin with 1 pump of K18 Mask and add more as needed depending on the length, thickness, and condition. Work it evenly into the hair from ends to roots, 1 pump at a time. Let it sit for 4 minutes to activate, then style as usual. Use for the first 4-6 washes, then decrease to every 3–4 washes.
