K18 Leave-in molecular repair hair mask 15ml

The K18 Leave-In Molecular Repair Hair Mask is a powerful, leave-in treatment designed for anyone dealing with damaged, colour-treated or over-processed hair who wants real, lasting repair.

Powered by the patented K18PEPTIDE™, this biotech-engineered formula works at a molecular level to reconnect broken polypeptide chains and disulfide bonds caused by bleaching, colouring, chemical services and heat styling.

Unlike traditional hair masks that coat or condition temporarily, this lightweight cream mimics the natural structure of hair to restore strength, elasticity and softness from within. In just 4 minutes, hair looks and feels smoother, stronger and more resilient, with results that continue even after your next wash.

Suitable for all hair types and textures, including fine, fragile and highly damaged hair.

Also available in a full size 50ml version.
