Award Winning

A leave-in treatment mask for all hair types that clinically reverses damage in 4 minutes. The patented peptide technology works to repair damage from bleach, color, chemical services & heat – restoring strength, softness, smoothness, and bounce to hair.

The K18PEPTIDE™ works at the innermost layer of hair, reconnecting polypeptide chains and disulfide bonds broken during bleaching, chemical services, and through heat damage.

By addressing these damage sites at the innermost layer of hair, core strength and elasticity are renewed for strong, smooth, bouncy hair—even after the most extreme damage done in the salon or at home.

Hair Concern : Dry & Damage, Frizzy

I have naturally dry hair, and i was disappointed. because i don't see any result after that. But after a few washes, it really did make my hair healthier and more glowing. It made my hair easier to comb. Now my hair doesn't need any hair oil to moisturize it, only this mask!

I didn’t see the difference from first use as everybody talk. But after a while it really works great for damage hair! Especially colored one. It will provide long-lasting benefits with regular use only.


Love it. No split ends anymore!
