A breakthrough leave-in hair mask that repairs damage at the molecular level in just 4 minutes.

K18 Leave-In Molecular Repair Hair Mask is a breakthrough hair treatment designed to repair and strengthen damaged hair at the molecular level.

Powered by patented K18PEPTIDE™ technology, this leave-in mask reconnects broken keratin chains caused by bleach, color services, heat styling, and environmental damage. In just 4 minutes, hair feels stronger, smoother, and healthier.

Unlike traditional conditioners that only coat the hair, K18 works inside the hair structure to restore long-term strength and elasticity.

Professional salon product trusted in Bombshell locations daily.
