K18Biomimetic Hairscience Leave-In Molecular Repair Hair Mask

Really good product. Use sparingly but does the job.

Love this mask. It makes hair look healthy and silky

Omg this is an absolute game changer it actually does what it says on the box , I’ve used everything including olaplex but nothing comes close to this used it once and could see and feel the difference my hair is badly frazzled from over bleaching apart from getting it cut short nothing I could do about it , I used 2 blobs as I have bobbed hair put it through all of my hair left it for the 4 mins like it says before I brushed and styled normally , yes it’s mega expensive but well worth it if your hair is as damaged as mine highly recommend this product ps dont buy it if it advertised for anything less than its original price which is £50 the cheaper ones are not the real deal I found that out the hard way 👍

This product is NOT THE REAL THING. my local hairdresser proved this. Do NOT purchase. Completely different look and texture to real productWould give 0 if I could

I was hesitating about purchasing this from Amazon, but as it is listed as an official seller by K18, I gave it ago, checking it was sold and fulfilled by Amazon. I checked the bottle against all the online videos comparing real and fake K18 and it was genuine. I then rubbed it in my hands and it emulsified like genuine K18 and finally it soften and smoothed my bleached straw hair. Will buy it again from Amazon. Anyone buying it will already know its a a painful purchase given the cost for quantity or product, but it's effectiveness is undeniable.

This has transformed my hair. I have very fine and fragile hair that breaks easily. I have never been able to grow it long because it gets so broken and shaggy. With this I have been able to grow my hair longer than usual and it gives an amazing shine. I will still never be able to have very long hair but I have actually never used a product that works as well as this. You don't use conditioner with this, and a small amount goes a long way. It is VERY expensive but when you have hair like mine it is worth it. I just put it on the ends and use a tangle teaser to comb through and let it air dry. Once it dries my hair feels a little crunchy at first but once I brush it through again it feel silky soft and shiny. It's definitely a five star product in terms of quality and ingredients but I've knocked a star off because of the high price, which also recently went up.

I’ve used K18 before, purchased directly from their website and I’m not certain the one I’ve been sold here is legitimate.When using previously I noticed an instant improvement in my hair with every use, and here I’ve not noticed any difference at all.I could be wrong but fear I’ve been sold a dupe.

So a positive review, I'm actually blown away by this little product. If you've been using this correctly then you should be seeing the results I'm seeing.So I was dying my hair blonde for years because I have stress alopecia and have bald patches on my head , being blonde it was less noticeable BUT my hair was dying ! So I took the drastic decision to go back to brunette and find something to rescue my hair.I've used a fair few product all claiming the miracle hair cure . But this has got to be the best, ok it's not cheap but you only need a little amount and smoothe it over the worst areas of your hair .So wash your hair in a cleanser shampoo , NO CONDITIONER then towel dry and use a little amount . Don't go overboard with this as it will end up like glue on your head.Air dry your hair don't use heat it defeats the purpose, you want to keep as much moisture in your hair not dry it out. Don't brush your hair while it's wet .Repeat this every time you wash your hair for at least 6 to 10 washes.It may seem like your hair feels dry but don't panic just let it do its thing . My hair has literally repaired itself it's crazy insane ...I'm back to using biotin shampoo and conditioner now but I keep this in and every so ofter I will do this routine now. The large bottle is better at this price as you get a lot in it and should last a while at least 30 treatments which personally I think is worth it for 34 quid . BargainJust remember to use it correctly and honestly you won't regret buying this
