K18 Molecular Repair Hair Oil 1 fl oz — strengthening peptide treatment, frizz control & heat protectant

K18 Molecular Repair Hair Oil is a lightweight, silicone‑free finishing and treatment oil that strengthens damaged hair, smooths frizz, and boosts shine while helping protect against heat styling.

This biotech‑inspired oil combines a patented peptide system with nourishing plant oils to address damage at two levels: reinforcing the inner hair structure and smoothing the cuticle surface. Designed for everyday use on all hair textures, the formula applies without weighing hair down or leaving buildup, making it suitable as both a repair step after treatments and a daily finishing oil for added shine and manageability.

How does this oil reduce frizz and strengthen hair?

The oil works on two fronts: it supports the hair fiber internally and smooths the outer cuticle. A patented peptide targets weakened areas of the hair matrix, while lightweight oils condition the surface, improving slip and reducing friction that leads to frizz.

• Peptide technology designed to support the hair’s inner structure.
• Avocado, sunflower oils, squalane and hemisqualane for surface nourishing.
• Silicone‑free, weightless texture that prevents buildup.
• Dual-action approach for internal support plus cuticle smoothing.

Can I use it with heat styling and color-treated hair?

Yes—apply before heat styling to add a protective layer and reduce additional styling stress. The formulation is also color‑safe and aims to enhance shine and vibrancy without leaving residue that dulls color.

• Use on damp hair prior to blow‑drying and flat ironing.
• Suitable for color‑treated, chemically processed, or natural hair types.
• Light texture keeps hair responsive to styling without stiffness.

How do I get the best results from this treatment oil?

Start small—1 to 3 drops—and increase only if needed. Apply to towel‑dried hair from mid‑lengths to ends after your leave‑in or mask, and use sparingly on dry hair to tame flyaways and add shine without greasiness.

• Apply after K18 Molecular Repair Hair Mask for a complete routine.
• Use on damp hair for repair and frizz control; on dry hair for finishing shine.
• Layer gradually to avoid overapplication; concentrate on ends and stressed areas.

Will it weigh down fine hair or cause buildup?

The formula is crafted to be weightless and free of silicones, minimizing the risk of heaviness or residue. Because it absorbs readily, most users find it enhances manageability and shine without flattening finer textures.

• Silicone‑free oils chosen for lightweight absorption.
• Designed to nourish without creating visible buildup.
• Apply sparingly on fine hair, focusing on ends to maintain volume.

Who this is for: K18 Molecular Repair Hair Oil is intended for people seeking a dual-purpose product that both repairs and finishes—anyone with frizz, split-end concerns, heat‑styled or chemically treated hair will benefit from its strengthening peptide plus lightweight conditioning. It fits into a restorative routine after professional or at‑home treatments and is also convenient as an everyday styling oil for added shine and smoother strands.
