About K18
A four-minute leave-in mask claiming to reverse bond damage is what put this brand on every hairstylist's Instagram feed. K18 built its reputation on peptide science aimed at repairing hair at a molecular level rather than just coating it in silicones, and it's become as much a salon-shelf staple as a retail one.
You'll see it recommended heavily by colorists and bleach-heavy stylists in particular. One quirk worth knowing: the generous 90-day refund window only applies to orders placed directly through the brand's own site, not purchases made at a salon that carries the line.
What they sell
- K18 Peptide Prep leave-in molecular repair mask
