K18 Molecular Repair Hair Oil — Lightweight Peptide Treatment 0.34 fl oz | 24‑Hour Frizz Control & Heat Protectant

This biotech-formulated oil blends the patented K18PEPTIDE with nourishing oils to address hair damage at two levels: the inner fiber and the outer cuticle. Silicone-free and weightless, the 0.34 fl oz bottle is designed for daily use on all hair types to reduce split ends, enhance shine, and smooth unruly strands without buildup.

How does this oil reduce frizz and repair damage?

The formula works on two fronts: it penetrates the hair fiber to strengthen and reverse damage, while also smoothing the cuticle surface to limit moisture-related swelling that causes frizz. Clinical performance data show improvements in shine and measurable reductions in split ends when used as directed.*

• Patented K18PEPTIDE targets the hair’s inner structure for repair.
• Cuticle-smoothing agents help keep strands aligned and less reactive to humidity.
• Lightweight emollients avoid weighing hair down while improving manageability.

How do I use K18 oil in my styling routine?

Start with 1–3 drops and add more only if needed. Apply to towel-dried hair from mid-lengths to ends for repair and frizz control, or use a small amount on dry hair as a finishing oil to smooth and add shine.

• After K18 Molecular Repair Hair Mask: apply oil to lock in repair and finish styling.
• Daily use: small dose on damp hair before blow-drying for protection and manageability.
• Finishing touch: rub a drop between palms and lightly smooth over flyaways and ends.

Will this oil weigh my hair down or leave buildup?

K18's oil is formulated to be weightless and free of silicones, so it nourishes without leaving greasy residue when used sparingly. The blend of avocado oil, sunflower oil, hemisqualane, and squalane is designed to absorb quickly and boost shine without flattening hair volume.

• Silicone-free formulation to minimize buildup over time.
• Hemisqualane and squalane provide silky slip with quick absorption.
• Use measured amounts to maintain natural body and movement.

How does this oil protect hair from heat styling?

The hair oil offers heat protection up to 450°F when applied prior to thermal tools, helping to reduce additional damage during styling. It’s intended as part of a routine that includes repair-focused products to address existing structural weakness.

• Apply on damp hair before heat styling to form a protective layer.
• Paired with K18 treatments, it reduces split ends and strengthens fragile lengths.
• Helps maintain color vibrancy and increases shine by up to reported percentages.*

Who is this for: K18 Molecular Repair Hair Oil suits anyone seeking a lightweight, science-driven finishing and protection oil—ideal for color-treated, chemically processed, heat-styled, or naturally frizz-prone hair. It works well for fine to thick textures because the dosing is adjustable: small amounts for thin hair, slightly more for coarser types. Use it to finish styles, add shine, or make repair-focused routines more effective.
