Reverse hair damage with the K18 Leave-in Molecular Repair Hair Mask, a leave-in treatment mask designed to restore the hair in just four minutes.
Bleach, colour treatment, chemical services and heat can all wreak havoc on the hair. Powered by the K18PEPTIDE™, this haircare treatment can help repair the damage. Giving both immediate and lasting results, it helps restore strength, smoothness, softness and bounce.
Working at the innermost layer of the hair, this vegan-friendly mask can even get to work on extreme damage. Boosting core strength and elasticity, it helps reduce split ends, breakage and colour fade. With lightweight moisturising benefits, it will not weigh down the strands as it helps prevent tangling for hair that looks and feels renewed.

MAGIC
This is the second bottle that I have purchased in the last 12 months. I love to dye my hair blonde and over the years I noticed that I have lost more than half of my hair, but then I came across this product and man my life has changed ever since. I highly recommend this product.

Bought multiple times
This is my number 1 go to for keeping my hair healthy, thick and thriving. I had a bad bleach job 2 years ago and tried so many products to help repair. I finally gave it and bought K18 mask as everyone raved about it and it absolutely did no disappoint. I've been using it for about a year now, on my 3rd or 4th bottle, and although I don't necessarily need it now, I still use it every few washes to keep my hair in amazing condition. P.S I've been able to use bleach again and have had blonde in my hair the last 3 hair appointments and my hair is still in amazing condition. Forget buying multiple styling products etc. All you need is this and a good heat protector and your hair will love you.

Good hair product
This hair product is really easy to use and apply. I normally use 4 pumps, then rub it in my hands till it turns into this white paste. I don’t use conditioner with it and finds that it hydrates my hair well and prevents tangling when my hair is wet. I can see improvement on the ends of my hair too.

Greatness
I purchased the small bottle to give it a try before investing in the bigger size. My hair are naturally curly and after wash I usually use my diffuser to define the curls. I can tell you that after using the leave in mask I did not need to do anything. You only need to put a small amount of product and style them. The curls looked amazing and healthier

K18
I've been impressed with this product for my split ends. After using it a few times, I've noticed a significant improvement in my hair's shine, frizz, and volume. Given my frequent use of heat styling, it's truly transformed my hair. The price is justified compared to other products I've tested. Definitely a repurchase for me!
