*Disclaimers

  • DO use a clarifying shampoo if you’re a heavy product or dry shampoo user to remove buildup and help our peptide penetrate and get where it needs to go.
  • DO wait the full 4 minutes before styling or applying other product
  • DO use every 4-6 shampoos consecutively to see and feel ongoing results
  • DON’T condition your hair before application (trust us, most won’t need it after K18, if you still need, add a leave-in after the 4-minute window is up post-application)
  • DON’T overuse, a little goes a long way.
  • DON’T rinse out. This is a leave-in, so you know, leave it in!

Get started here
K18 is engineered to work with every hair type, in every service, and with every routine.
Traditional conditioners leave a film on hair 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 styling product.
Water in damp hair swells the cuticle (the outside layer of hair) to open the gates for our biomimetic peptide to enter and travel to the innermost layers of hair. If the gates aren’t open, the product will stay on the surface—giving you mostly superficial repair. By applying on damp hair, you can use less, waste less, and still get the best results.
Think of the K18 mask as a highly concentrated treatment. It restores hair’s strength + elasticity in the innermost layers of hair, instead of traditional conditioners that coat the outside of hair. After the 4-minute wait time post-K18 mask, feel free to add a leave-in for a boost of conditioning if needed.
Yes, both formulas are the same. The PRO mask is conveniently sized for PRO use.

    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
