A leave-in treatment mask that works on the molecular level to reverse hair damage in just 4 minutes. The K18 PEPTIDE is clinically proven to repair damage from bleach + color, chemical services and heat* – with immediate and lasting results to restore strength, softness, smoothness and bounce to hair.
Takes damage repair further – reconnects both polypeptide chains (and as a result, also reconnects disulfide bonds) for strength along the length + width of the hair - offering comprehensive, lasting damage repair
Restores hair from even extreme damage - by working at the innermost layer of the hair, core strength and elasticity are renewed for strong, smooth, bouncy hair
Delivers immediate and lasting results – hair is repaired from the first use and lasts past your next wash, for ongoing reparative benefits
Simplified repair - convenient, leave-in formula works in just 4 minutes, with no extra rinse required
Works on all hair types – because K18PEPTIDE works on a molecular level (where all hair is the same), this product is effective on all hair types
DOs and DON'Ts
-DO clarify before K18 if you’re a heavy product user (demineralize for mineral + metal buildup)
-DO apply on clean, damp hair
-DO wait the full 4 minutes before combing or styling
-DO add whatever styling products you love after the 4 minutes

Healthier Hair in 4 minutes¹
¹healthy hair - We define healthy hair as hair that exhibits a combination of strength, elasticity, manageability, softness, smoothness, vibrancy, shine and is frizz free' but note that we’re not providing data as substantiation against each of the descriptors where we make healthy hair claims. This also doesn't describe 'healthiest'.
