got questions?

Get started here

Is K18 mask considered a protein?

No, the K18 mask is not a protein treatment. Our biomimetic peptide naturally mimics the amino acid sequences in keratin to rebuild bonds broken by bleach* + color*, chemical services*, and heat* damage. If you are experiencing dry, brittle hair, use K18 PEPTIDE PREP™ detox shampoo pre-K18 mask to remove buildup. *Disclaimers

Why skip conditioner?

Conditioner leaves a film that blocks our peptide from penetrating effectively. Once the 4-minute wait time is up, feel free to use a conditioner, a leave-in, or any type of product.

Will the detox shampoo dry my hair out?

No, the detox shampoo will not dry your hair out. This non-stripping formula has a pH of 3.8-4.2 that won’t leave hair over-stripped. In a consumer study, 90%* said hair feels clean without feeling dry. *Disclaimers

Will the detox shampoo strip color?

No, the detox shampoo will not strip your color. This color-safe formula is optimized with pH 3.8-4.2 to help maintain your color, and uniquely targets common metals present in tap and hard water that can cause dullness.

What is the K18PEPTIDE™?

Our biomimetic peptide mimics hair’s natural structure to seamlessly fit in and reconnect broken keratin chains responsible for hair’s core strength and elasticity. As a result of this reconnection, it also addresses cleaved disulfide bonds for connection along the Y-axis of hair AND the x-axis, or width, of hair.

Miracle Worker

Absolute LOVE. It repaired the health of my hair in just one use. I have dark brown hair and like to have ashy blonde highlights. Before using, my hair was dry, frizzy and would break. After a few uses, it's almost like I've never used bleach. This will be a staple in my routine from now on

From drab to fab!

I certainly see, and feel the difference in hair hair with the use of the products. Wanted to see how well they’d help my hair recover following a few botched hair colors and corrections. The pictures don’t really do it justice.
