Do's and Don'ts
  • 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 another 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!

Leave-In Molecular Repair Hair Mask
I really don’t know where to start. My stylist strongly recommended this product so I switched to k18 and I'm NOT HAPPY. My hair went from soft and fluffy to dry and dull. I followed the instructions and didn’t use conditioner so k18 can do its magic, so far crickets. Not sure how much more I can take. I figured for what I paid I would have magical unicorn hair but I don’t.

This outrageously expensive product made my hair feel worse every time I used it. It is nothing more than an over priced lousy conditioner and shouldn’t be sold at any price. Please don’t waste your money.

Leave-In Molecular Repair Hair Mask
My hair is very thick, damaged and gets frizzy in humid conditions. i have to do deep conditioning treatments and keratin treatments quarterly. After four minutes my hair looked how it looks after a keratin treatment. Totally worth the money!

My long thick curly hair was severely damaged (fried) trying to perform a @jackmartincolorist silver transformation. It was my own my own fault for not having the patience to grow out the excellent salon brand dark color i had been using for almost 30 years. K18, if used as directed (yes, less is more), has saved me from having to cut off all my hair while i now wait patiently to grow it out naturally. Even my hair stylist noticed the improvement. I love this product, and will always keep it on hand to keep my hair healthy. Can't wait for the new shampoo to be made available to the general public.

Big hype on Social Media about this product, and I was pleased to find out BCC carry it. I ordered this small bottle with tax etc. $31 dollars and some change. WOW "Very little product" is needed. First time I used 2 pumps for my thin shoulder length hair, it did nothing. Second time 4 pumps, third and last time 6 pumps. Unfortunately this product did absolute zero for my hair. I would not recommend it. Maybe it's the texture of my hair, never the less it was not for me.
