Molecular Repair Hair Oil

This biotech-engineered weightless oil works on all hair types to strengthen, repair damage, reduce frizz at two levels of the hair fiber, and improve shine.

Reverses damage caused by frizz
Smooths frizz and flyaways
Enhances shine and color vibrancy

This strengthening, smoothing hair oil works on two levels of the hair fiber to fight frizz. The K18PEPTIDE™ works to address deeper level damage that causes frizz, repairing and strengthening damage at the innermost layer of the hair fiber to reverse damage that leads to frizz.

On the surface of hair, natural oils like avocado and sunflower oil and hemisqualane and squalane nurture while smoothing frizz and flyaways to improve color vibrancy, enhance shine, and provide heat protection up to 450°F (232°C).

Clinical Results:
In a 3rd party clinical study, one use of the K18 Molecular Repair Hair Oil delivered:

- 24-hour frizz control*
- 104% improvement in shine**
- 78% reduction in split ends***

*Results observed on curly, frizzy hair after 24 hours in 80% relative humidity, with one application of molecular repair hair oil on dry or damp hair
**Results observed after a single application of molecular repair hair oil on dry hair

Looks greasy

I have fine hair that is dry due to overheating and this oil only makes hair look super greasy. Even using a tiny amount will make hair look dirty.
