This at-home leave-in treatment powered by patented K18PeptideTM is clinically proven to
reverse hair damage from bleach + color, chemical services, and heat to renew strength, softness,
smoothness, and bounce.

I have fine/medium straight hair with dry ends due to bleach. I wash my hair about 3 times a week, and once a week I use the Moroccan Oil hydrating hair mask. That being said, I feel like I haven't used this product enough times and on a consistent basis to be able to tell if it was actually improving my hair texture, but I did finish the whole bottle and there wasn't much of a difference in my hair texture. This product is unique because to use it correctly, you aren't supposed to condition your hair in the shower, which is how it differs from a standard leave-in conditioner. It did leave my hair feeling pretty soft, but for me personally, I'd probably just stick to my normal hair care routine that leaves my hair feeling the same way. It may be ideal for people who would want to skip a step in their haircare routine, but I like to always have equal amounts of shampoo and conditioner lol

Being in the beautycare business allows you to try many different products,some that become a part of your everyday care regimen,and the K18 leave-in Molecular repair hair mask has become one for me. Between coloring My hair and using a hot blow dryer, and flat iron,my hair has become very dry and brittle. I have tried many different products hoping to bring my hair back to looking and being healthy again,and by using the K18 hair repair mask,I have achieved that. I wouldn't have believed it myself had I not tried it on my own hair. This mask works by repairing the keratin bonds in your hair by using the k18 peptide,the Peptide then transports amino acids into the hair shaft which helps to repair the damaged bonds. After shampooing you simply add this creamy formula to your towel-dried hair. I have long hair and used 2 pumps to saturate my hair. My hair looks and feels the healthiest it's been in a long time. I just love how soft it is now,and no more frizz. This is one product that I will continue to use.

To be honest I was supper skeptical about this product, I kept seeing advertising for K18 all over Instagram and i wanted to give it a try. And omg! It did not disappoint!!! My hair was super damaged and impossible to do anything with it anymore I even considered shaving my head at one point! Lol but K18 is amazing! And it’s definitely doing wonders to my own hair. I swear by this product so much Im on my 3rd bottle because I started using it on my clients as well, I always recommended to everyone and anyone that wants to completely repair their hair’s integrity! The first time I used it on my hair I used about 6 pumps but I feel like that was extremely necessary because like I said before my hair was fried!!! The second time I used it we started to feel my hair softer and easier to brush, by the 3rd and 4th time i was actually able to blow dry my hair, which was almost impossible before because i had so much breakage and it would also que stuck on the round brush. I feel like my hair is still on repair mode rather than maintenance mode just because of how damaged it was, but I have little to no breakage now and that makes me super happy! Truly an amazing product!! **This review was created through an educational promotional event hosted between the brand and beauty experts.**
