K18 Hair Oil
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 hair to reverse damage
that leads to frizz.
On the surface of hair, natural oils like avocado and sunflower oil,
and hemisqualane and squalane nourish while smoothing frizz + flyaways
to improve color vibrancy, enhance shine, and provide 450°F (232°C) heat
protection.
