K18 Molecular Repair Hair Oil 1 fl oz — Lightweight, Silicone-Free Heat Protectant & Frizz Control

If your hair struggles with breakage, frizz, dullness or split ends, this engineered oil blends K18's patented peptide technology with nourishing botanicals to target damage at multiple layers of the fiber. Designed for everyday styling and finishing, the formula works on all hair types—fine to coily—and layers easily without weighing hair down or leaving residue.

How does this oil reduce frizz and repair hair?

The oil pairs the K18PEPTIDE, which acts on the inner structure of the hair, with surface-conditioning lipids that smooth the cuticle. Together they address the root causes of frizz and restore manageability over time rather than only masking symptoms.

• K18PEPTIDE penetrates the hair fiber to strengthen and reverse damage.
• Avocado and sunflower oils replenish moisture and improve elasticity.
• Hemisqualane and squalane smooth the cuticle for immediate slip and shine.

Will this weigh my hair down or cause buildup?

No—this formula is intentionally lightweight and free of silicones so it absorbs quickly and leaves hair feeling soft, not greasy. It’s designed for repeat use and to complement other treatments without buildup that can dull color or weigh strands.

• Silicone-free base keeps hair airy and non-greasy.
• Use 1–3 drops initially, increasing only if needed for thicker or coarser hair.
• Works on both damp hair for treatment and dry hair for finishing polish.

How does it protect hair from heat styling?

The oil provides thermal protection for styling tools and helps limit the additional wear that high temperatures cause. It’s formulated to shield strands up to styling temperatures while enhancing shine and reducing split-end formation.

• Heat protection compatible with styling tools—designed to help prevent further heat-related damage.
• Reduces split ends and supports smoother styling results.
• Applies easily before blow-drying or straightening for better slip and control.

How should I use K18 Molecular Repair Hair Oil in my routine?

Apply a small amount to damp, towel-dried hair from mid-lengths to ends after washing or following the K18 Molecular Repair Hair Mask for a complete strengthening sequence. Use a drop or two on dry hair to tame flyaways and add shine as a finishing step.

• Start with 1–3 drops; distribute evenly through mid-lengths and ends.
• Layer over K18 mask for intensified repair results.
• Use on dry hair to smooth frizz and boost glossy finish.

Who is this for? K18 Molecular Repair Hair Oil is ideal for anyone seeking long-term improvement in hair strength and manageability—people with chemically treated, heat-styled, color-treated or naturally frizz-prone hair will benefit most. Because it’s lightweight and silicone-free, it suits fine to thick textures and can be added to daily styling without weighing hair down. If you want a peptide-enhanced oil that combines repair, shine and heat protection in a single 1 fl oz bottle, this is formulated for you.
