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.
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.

I moved to Colorado a year ago and live on well water now. I have never dealt with all this mineral build up before and have had trouble finding a shampoo to strip the build up off my hair. My hair has become incredibly dull looking in the last year. After just one wash, I could tell a significant difference in the way my hair looked and felt. I’m currently using it once a week to keep the build up under control. Highly recommend to use if you are having the same issue as me!

My hair stylist turned me onto this product. I have naturally curly hair which tends on the dry side and I color my hair. I have searched for a product for years that does what this product does for me. It is amazing the transformation in just one application sis for my hair. I find I actually need less styling product also, my hair now has a healthy moisture content and my curls have never looked better.
All the products I have tried to nourish and hydrate my curls have only done the opposite.
This product helps with my frizz and I find I can extend time between washes.
Call my 100% happy with K18 Leave In.
Highly recommend

My hairdresser started using this on me as my hair had started breaking off and drying out after a recent weight loss. The changes in my hair with this product along with the peptide prep shampoo are unbelievable! I now only wash my hair every 2-3, sometimes to the 4th day and my hair is so much healthier and fuller. Love your products!

I’ve been using this product along with a K 18 molecule repair oil for about three months and they have changed my hair. Before using them, my hair seem to be a little dry not shiny sort of blah but now after using them, my hair shines. It’s beautiful. I just love it..
