Transform damaged, frizzy hair from the inside out with the K18 Molecular Repair Hair Oil, a weightless, biotech-powered styling oil designed to reverse the damage that causes frizz. Powered by the patented K18PEPTIDE™, this high-performance oil goes beyond temporary smoothing by working at the molecular level to repair damaged keratin bonds, fortify the hair barrier, and strengthen hair against future breakage.

Engineered with dual-action performance, it smooths stubborn flyaways and split ends while offering heat protection up to 450°F / 232°C, delivering long-lasting frizz control, enhanced color vibrancy, and mirror-like shine without weighing hair down.

Key Benefits & Features

  • Molecular-Level Repair: Reconnects broken disulfide and polypeptide bonds to heal inner-core damage and restore long-term hair strength.

  • 72-Hour Frizz Control: Instantly tames unruly frizz, flyaways, and static while shielding against high humidity.

  • Heat Protection up to 450°F (232°C): Protects fragile strands from thermal damage caused by blow-dryers, flat irons, and curling wands.

  • Weightless Softness & Shine: Deeply nourishes and enhances color vibrancy without leaving a heavy, greasy, or sticky residue.

  • Silicone-Alternative Formula: Formulated with natural oils (like avocado and sunflower oil) that feed the hair without coating it in heavy silicones that cause long-term buildup.

  • Universal Compatibility: Safe and effective for all hair types—including fine, coarse, straight, wavy, curly, coily, and color-treated hair.
