Get started here
The K18REPAIR™ service works by reversing damage before and after services for stronger, more resilient hair. K18 PRO mist restores chemically damaged hair before services, making hair more resilient for salon transformations. Use before services for a stronger foundation and to help prevent damage during services. Follow with the K18 PRO mask to reverse damage done during services and to soften, smooth, and condition hair.

The K18PEPTIDE™ powering both formulas reverses damage from bleach* + color*, chemical services*, and heat* in 4 minutes. It works by reconnecting breaks in the hair fiber along both the length (keratin chains) and the width (disulfide bonds) for holistic hair renewal.

*Disclaimers
K18 is engineered to work with every hair type, in every service, and with every routine.
We recommend misting hair with water before using the PRO mist to swell the cuticle layers and open up the hair fiber, allowing for maximum penetration of the peptide-powered PRO mist into the innermost layers of hair. In the same way a damp sponge absorbs more water, damp hair absorbs K18PEPTIDE™.

If you’re using the PEPTIDE PREP™ pro chelating hair complex, there’s no need to mist the hair with water before using the PRO mist.
K18 PRO mist will not interfere with toner or final color. In clinical testing, we’ve found that color lasts longer + fades slower* when paired with mask usage at home.

*Disclaimers
K18 PRO mist + mask are not protein treatments, our biomimetic peptide naturally mimics the amino acid sequences in keratin to rebuild bonds broken by bleach, color, and chemical service damage. If your clients are experiencing dry, brittle hair, use PEPTIDE PREP™ detox shampoo pre-K18 mask to remove buildup.

    Love it

    My hair is extremely thin and fine and has tons of damage and breakage. My ends were like straw. I decided to try this based on Abby's recommendation from YouTube. I used it 4 times in a row and now use it once a week. I do think I'm seeing results as my ends are looking better. It's expensive but a little goes a long way and while it's still a little early, I'd say it's worth it. Before and after pic included.

    AAMAZING!!!! AAMMAAZZIINNGGG!!!!!!!!! AAMMAZZINNGGGG!!!!!!

    I was honestly very scared to use, especially not rinsing and conditioning. Because usually other products have you wait 10 minutes and rinse and condition. All my other products I WILL BE THROWING AWAY!!!!!! THIS PRODUCT IS A MUST HAVE. Last night was my first time using it.. i have DEFINITELY NOTICED A BIG CHANGE in my bleached hair with one use!!! I first used the Damage K18 shampoo, then 2 pumps of this GOD SENT PRODUCT LEAVE IN MOLECULAR REPAIR HAIR MASK, then used the k18 hair oil and blow dryed. And i have never ever noticed such A DRAMATIC CHANGE IN MY HAIR!!!!! I have been missing out all this time. Especially because it took me 5 years to go completely bleach blonde and I could've been using this product all along. I KNOW ITS PRICEY (FOR ME A SINGLE MOM IT IS VERY EXPENSIVE) BUT IT IS WELL WORTH IT, I NEED A LIFETIME SUPPLY. Thank you K18 for such an amazing bomb product. Definitely a 20 star product. Can't wait to see my hair results after 6 times of using it!!!!!!!!!!!!!

    Really works

    There’s so many products that say that will help with chemical damaged hair, my hair is blonde and to be blonde it can really damage your hair. I noticed that my hear is getting healthy less breakage softer. Don’t forget to use a heat protector after.

    Definitely helps!

    My hair was chemically damaged and a large piece broke off. I’ve used this twice since then (so far) and it’s helped me not lose a lot more hair, and I’ve noticed less tangles. My hair has been so much softer and my curls are happier too. I’m definitely going to keep using this product. I only gave 4 stars because I do still have more breakage happening and I had to cut off quite a bit
