Conquer frizz at its source while restoring structural strength with the K18 Molecular Repair Hair Oil. Engineered with biotech precision, this weightless hair oil works on two levels of the hair fiber to repair damage while delivering immediate shine and smoothness. Powered by the patented K18Peptide™, it penetrates deep into the inner cortex to reverse the structural damage that causes frizz, while natural squalane and avocado oil smooth the surface cuticle to seal in moisture. Ideal for all hair types, this silicone-free formula provides thermal protection up to 450°F (232°C) without weighing strands down or leaving a greasy residue behind. It is the ultimate finishing step for achieving glossy, resilient, and touchably soft hair. Key Benefits: Molecular Damage & Frizz Repair - K18Peptide™ repairs internal structural damage at the core to target the root cause of frizz. Surface Smoothing & High Shine - Squalane and avocado oil smooth the outer cuticle to instantly tame flyaways, boost color vibrancy, and add luminous gloss. 450°F Thermal Protection - Shields fragile strands against extreme styling heat up to 450°F (232°C) to prevent future breakage and moisture loss. Weightless & Silicone-Free - Delivers deep hydration and softness without leaving heavy buildup, grease, or weighing down your natural movement.
