K18 Molecular Repair Hair Oil

K18 Molecular Repair Hair Oil is a lightweight, biotech-engineered oil made for every hair type, especially strands that deal with ongoing frizz, flyaways, or dullness. It's silicone-free, and it applies as a few concentrated drops that melt into hair rather than sitting on top of it — no greasy film, no weighed-down roots, just a smooth, glassy finish and an immediate boost of shine. A little truly goes a long way: most people only need one to three drops per use.

Apply to damp, towel-dried hair before styling for strengthening benefits, or smooth a drop or two through dry hair as a finishing step for shine and flyaway control. K18PEPTIDE™ is formulated to work at the innermost layer of the hair fiber, targeting the deeper structural damage that causes frizz to keep coming back, and K18 recommends waiting four minutes after applying to damp hair before styling to let it take effect. On the surface, natural avocado and sunflower oils pair with hemisqualane and squalane to smooth the cuticle, boost color vibrancy and shine, and provide heat protection up to 450°F (232°C) — working on two levels of the hair fiber at once. It layers well after the K18 mask, applied once the mask's four minutes are up.
