K18 sells peptide hair care products to reverse hair damage.

K18 earns strong reviews for visibly repairing damage and boosting shine and softness—especially on bleached, heat-styled, or frizz-prone hair—yet feedback is mixed on the leave-in mask’s results for healthy hair. Reviewers praise the lightweight oil, innovative AirWash dry shampoo, and fast, non-greasy finish, while noting drawbacks like potential heaviness or clumping if overused, harsh shampoos for some, residue and limited longevity from AirWash, and occasional scent and buildup concerns.
