4.5

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.

It leaves my scalp feeling refreshed and my hair feeling lighter and cleaner. Perfect for a reset between washes, especially if you use styling products regularly!
