Overview
The K18 Leave-In Molecular Repair Hair Mask is a concentrated four-minute treatment made to restore strength and elasticity in damaged hair. It uses peptide technology to work inside the hair shaft rather than coating the surface. It suits all textures, including colour-treated, bleached and heat-styled hair, and is a practical at-home option for anyone wanting longer-lasting repair between salon visits.
