K18 Molecular Repair Hair Oil 1 oz is a lightweight, biotech-engineered hair oil designed to strengthen damaged hair, reduce frizz, smooth flyaways, minimize the appearance of split ends, and enhance shine without weighing hair down. Suitable for all hair types, this highly concentrated treatment combines K18's patented K18PEPTIDE™ with nourishing oils to address both deeper damage within the hair fiber and surface-level frizz.

The silicone-free formula provides 24-hour frizz control, helps increase shine, reduces split ends, and offers heat protection up to 450°F / 232°C. It can be applied to damp hair before styling for strengthening and frizz control or used on dry hair as a finishing oil for added smoothness and shine.

What It Does

K18 Molecular Repair Hair Oil works on two levels of the hair fiber. K18PEPTIDE™ targets deeper-level damage associated with frizz, while avocado oil, sunflower oil, hemisqualane, and squalane work at the surface to nourish and smooth the cuticle.

This combination helps strengthen damaged hair while immediately controlling frizz and flyaways. According to K18's testing, the oil provides 24-hour frizz control, 104% more shine, a 78% reduction in split ends, and heat protection up to 450°F.
