K18
K18 leave-in molecular repair hair mask mini
PRODUCT DESCRIPTION
A leave-in treatment mask that works on the molecular level to reverse hair damage in just 4 minutes. The K18PEPTIDE™ 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.
Benefits & Key Features:
-
K18PEPTIDE™ is a biotech-developed peptide that mimics hair's structure to reverse damage by reconnecting polypeptide chains and disulfide bonds broken during bleaching, color and chemical services + heat*.
-
pH-optimized (5.0-6.0) to help minimize cuticle swelling + put hair proteins in their most resilient state
-
Cream format enables easy, lightweight application across all hair types, with detangling and softening benefits
-
Vegan, color-safe, cruelty-free
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
