K18 Leave-in Molecular Repair Hair Mask is an at-home hair treatment infused with patented K18Peptide that works to repair even the most extreme damage, renewing hair to it's most youthful, healthy state.
This patented K18Peptide creates hair like new by travelling deeper into the inner layers of the hair compared to traditional repair products, to reconnect broken keratin chains, renewing hair strength, softness, smoothness, and bounce. You can feel and see the difference with the first use. This formula doesn't wash away with shampoo, leaving lasting results, healing damage from bleach, colour, chemical services and heat.
how to use
how to use
Shampoo, do not condition so the mask will penetrate hair more effectively. Towel dry hair until damp. Start with one pump and add more as needed. A little goes a long way. Work evenly into hair, one pump at a time, starting from ends to roots. Let sit for four minutes to activate. Do not rinse out. Style as usual.
Tips:
Use a clarifying shampoo if you're a heavy product or dry shampoo user to remove buildup and help the peptide penetrate and get where it needs to go. Wait the full 4 minutes before styling or applying other product.

This product has made my hair look and grow back so good from years of bleaching my hair it’s finally healthy again
I am happy with it
Noticed improvement from first use
Seems good—time will tell. But Cloud 10 were brilliant in delivering the item so quickly.
Great prodcut, I can visibily see it repairing my ends even after a few uses.
Class, I was a bit sceptical about the instruction to not use conditioner but after letting it sit in for 4 mins my hair was like silk to brush
Good
So far so good. Only used it three times and can see an improvement already
By far the best hair mask I have used. My hair was damaged from heat and bleaching I could see the difference from the first use
Leaves your hair soft and healthy feeling
Brilliant
Unreal product I have generally dry hair and it’s so so soft after using this
Is good product
Love this product

Great hair care product, helped smooth my hair in only 5 washes. Great price, nowhere near as affordable on any other website!
Completely damaged my hair and caused severe breakage. One look at the ingredients : alcohol is the main one! If you already have dry or damaged hair it can only destroy it more.
Amazing
Great for hair growth.
I love this. I bought small bottle just to try and I will be purchasing the bigger one next.
I was recommended this by my hairdresser after having it bleached and toned. I have quite dry hair naturally, and was hoping this would revive it as it was damaged by the bleach. It helps a bit, but not as much as I was hoping. I find I have to use an awful lot of it and my hair still feels very dry after use, so I add in some hair oil. Perhaps it's better suited for less dry hair? I would recommend trying it, and I'm going to continue use to see how it goes - just not sure it's worth the cost.
Amazing
Saved my bleached hair
I was expecting a lot from this product, but I was disappointed as it did very little for my dry frizzy hair.
I got this after reading great reviews but for the price I don't feel it's great. You need more than 2 pumps if you have medium lenght hair, after a week of using it it's almost gone. My hair doesn't feel any different.
