K18 Leave-In Molecular Hair Repair Mask 50ml

K18 Biomimetic Molecular Hair Repair Mask 50ml delivers salon-grade restoration in just 4 minutes. Powered by the patented K18Peptide, this lightweight leave-in treatment reconnects broken keratin chains to rebuild hair from the inside out. Clinically proven to reduce breakage, improve elasticity, and restore lasting shine and manageability, it transforms chemically treated, heat-stressed, and severely damaged hair into stronger, softer, more resilient strands. Benefits include immediate strength gains, reduced split ends, enhanced elasticity, frizz control, and cumulative improvement with regular use. Key ingredients: patented K18Peptide and a vegan, cruelty-free base free from parabens, sulfates, silicones, phthalates, sodium chloride, artificial colors, and formaldehyde. How to use: shampoo and do not condition, towel-dry, apply a small amount to mid-lengths and ends, distribute evenly, and leave in for 4 minutes—no rinse required—then style as usual. FAQ: Is it rinse-out? No, it’s leave-in. How often? Use after every wash for best results; visible repair typically appears after a few applications. Safe on color-treated and chemically processed hair. Who it’s for: anyone with damaged, bleached, colored, heat-styled, or brittle hair seeking fast, science-backed repair and lasting manageability.
