K18 reviews and discussion
Reviews mention
- Lightweight oil, silky finish
- Fast-absorbing mask, non-greasy feel

- Frizz-taming performance, lasting shine
- Harsh shampoos, scalp dryness
- Airwash residue, limited longevity
- Mask heaviness, clumping risk

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.

I had received a free sample of the k18 leave in conditioner and I LOVED it so I purchased the full size. Not sure what happened to the formula. It didn’t seem to work as well and it weighed down my hair after only one day. The full size doesn’t last that long and it’s very expensive.
