K18 Molecular repair hair mask 15 ml

K18 Molecular Repair Hair Mask is a leave-in treatment built for hair that's been through it — bleach, permanent color, chemical services, heat styling, or just years of everyday wear. It's designed for every hair type, and it applies as a rich, silky leave-in that melts through strands in seconds. There's no heavy, waxy coating and no lingering weight once it's in — just a smoother, springier feel that's noticeable within minutes of applying it.

Work it through clean, towel-dried hair after shampooing, then wait four minutes before styling or moving on to the next step — no rinsing is needed, since it's designed to stay in the hair. At the center of the formula is K18PEPTIDE™, a patented biomimetic peptide developed with researchers at the University of Minho, engineered to interact with the hair's own keratin structure and help repair the look and feel of damage from within, rather than sitting on the surface like a traditional mask. It's designed to be used as a stand-alone treatment on wash day, or as the first step before the K18 Molecular Repair Hair Oil for an extra layer of styling and strengthening.
