K18 Molecular Repair Hair Oil

Weightless Peptide Hair Oil for Damage Repair, Frizz Control and Heat Protection

K18 Molecular Repair Hair Oil is a lightweight peptide treatment oil built around the patented K18PEPTIDE (sh-Oligopeptide-78), engineered to work inside the hair fibre while a blend of Squalane, hemisqualane and sunflower oil smooths the surface. The 30 ml formula targets damage from heat, colour and styling, helps control frizz at two levels of the hair fibre, and offers heat protection up to 232 °C.

Why Choose It?

• Patented K18PEPTIDE (sh-Oligopeptide-78) helps reconnect broken keratin bonds inside the hair fibre
• Squalane and hemisqualane (C13-15 Alkane) reinforce the moisture barrier for frizz control at two levels of the fibre
• Helianthus Annuus (Sunflower) Oil and Persea Gratissima (Avocado) Oil nourish and add shine without buildup
• Heat protection up to 232 °C before blow-drying or hot tools
• Weightless finish on all hair types — supports softness, smoothness and reduced split-end appearance

Best For

All hair types — particularly damaged, colour-treated or heat-styled hair that needs frizz control, shine and heat protection before styling. The lightweight texture suits fine and medium textures that struggle with heavier oils.

Use as a finishing or pre-styling oil on damp or dry hair. For deeper bond repair, pair with a K18 peptide repair mask before applying the oil.

• Towel-dry hair after washing, or apply on dry hair for finishing.
• Dispense 1–2 drops into the palms (more for longer or thicker hair).
• Rub the palms together and distribute evenly through the mid-lengths and ends, avoiding the roots on fine hair.
• Comb through to spread the oil before blow-drying or styling.
• Re-apply 1 drop on dry hair as needed to smooth flyaways and add shine.

Tips

• Start with the smallest possible amount — the formula is weightless and 1–2 drops cover most lengths.
• Use before heat styling to benefit from the heat protection up to 232 °C.
• For chemically treated or very damaged hair, layer over a peptide bond mask for stronger repair before applying the oil.
