Get started here.
what is the K18PEPTIDE™?
Patented biomimetic peptide uniquely matches and clicks into hair's keratin structure, reconnecting damage sites at the molecular level. K18PEPTIDE™ repairs multiple types of bonds and polypeptide chains for strong, soft, smooth, bouncy hair for all.
why do I need to skip conditioner before using the K18 mask?
Conditioner leaves a film that blocks K18PEPTIDE™ 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.
why should I use detox shampoo before the mask?
Clean hair helps optimize results from products and treatments, like K18 molecular repair formulas. This detox shampoo effectively clarifies hair of buildup and metals common in tap and hard water, including 99% of product buildup, 95% of sebum + 76% copper after just 1 wash* while our patented K18PEPTIDE™ helps to maintain hair strength with no fillers or deposits left behind.
Repair damage for hair like new* in 4 minutes.

The stylist who cut my hair used the K18 Leave-In Molecular Repair Hair Mask and recommended that I try it at home. I’ve now been using it every other day for two weeks, and I already love the difference in my hair. My curls feel bouncier and looser instead of tight and stiff, and I especially love how my hair looks and feels.
The instructions say to leave it on for four minutes before applying your other products, but what I love most is that I don’t really need anything else. I can use my usual styling products if I want to, but I no longer have to use them every day to get curls that look and feel good. It saves me time and may even save me money because I’m using less of my other products.
I haven’t found anything I dislike about it so far. This has made my hair routine much easier, and I would definitely recommend it. Five stars!

From the first application, you'll be pleasantly surprised! I feel like I am sliding down a slippery slope with my aging hair. After trying countless products that didn’t deliver on their promises, I finally found one that truly works. This one is a game changer! It not only makes my hair smoother & bouncier, it's also fuller to the touch. I am a true believer, and you should be too!
