by K18 · hair_care
Editor's Take
K18 earns its repair language: the patented peptide goes beyond ordinary oil shine, while squalane and volatile alkanes keep the finish light and silicone-free.
Four-pillar formula scores
- Efficacy: 8.1 / 10
- Modern Tech: 9.0 / 10
- Clean Beauty: 8.3 / 10
- Sustainability: 7.3 / 10
The Verdict
Technology is Cutting Edge, with K18Peptide™ addressing structural damage while squalane, hemisqualane, and volatile alkanes smooth frizz and add shine. Efficacy is Excellent, and the Clean score is Excellent, though undisclosed fragrance and several allergens weaken an otherwise disciplined leave-on formula. Sustainability is Very Good thanks to bio-based emollients and no persistent silicones. A credible treatment oil that offers more than cosmetic gloss.
