The K18 Molecular Repair Hair Oil is a professional-grade, weightless styling oil engineered to reverse damage and eliminate frizz at two different levels of the hair fiber. Powered by the patented K18PEPTIDE™, this bio-active oil penetrates deep into the inner cortex to repair the underlying structural damage that causes long-term frizz. Simultaneously, a curated blend of natural oils—including avocado oil, sunflower oil, hemisqualane, and squalane—works on the hair's surface to instantly smooth flyaways, enhance color vibrancy, and provide advanced thermal protection up to 450°F (232°C).
Available Sizes: 0.34 fl. oz. (10 ml) | 1.0 fl. oz. (30 ml)
Key Benefits
-
Dual-Action Frizz Control: Rebuilds broken internal hair chains with peptide biotechnology to stop frizz at the source, while surface oils instantly tame environmental flyaways.
-
High-Heat Thermal Shielding: Protects delicate hair strands from severe thermal damage and structural degradation caused by hot tools up to 450°F (232°C).
-
24-Hour Frizz Defiance: Clinically proven to block out humidity and keep styles looking completely smooth, sleek, and polished all day.
-
Luminous Shine & Color Pop: Smooths the hair cuticle to drastically improve light reflectivity, delivering a high-gloss finish and boosting dimensional color vibrancy.
-
Weightless Hydration: Deeply nourishes coarse, dry, or split ends without leaving behind a heavy, greasy, or separation-prone residue.
How to Use
-
Dose: This formula is highly concentrated. Start by dispensing just 1–3 drops of the K18 Molecular Repair Hair Oil into your palms and rub them together to activate. Build with more drops only as needed.
-
For Damp Hair (Strengthening & Frizz Defense): Apply from mid-lengths to ends before blow-drying or air-drying. Crucial: Wait exactly 4 minutes to allow the peptide to fully bond to the inner cortex before styling or applying other products.
-
For Dry Hair (Finishing & Shine): Apply a tiny amount directly to your finished style to instantly capture flyaways, smooth down separation, and add a brilliant, reflective coat of shine.
Pro Tip: For the ultimate molecular repair cocktail, always layer your K18 products correctly. If you are using the K18 Leave-In Molecular Repair Hair Mask, apply the mask first to clean, damp hair and wait 4 minutes. Without rinsing, apply the K18 Molecular Repair Hair Oil right over it, and wait an additional 4 minutes. This combo locks in maximum structural strength, heat protection, and a glass-like finish.
