K18 Biomimetic Hairscience Leave-In Molecular Repair Hair Mask

Excellent productJust love this creammy hair looks soft and shiny

Has worked to significant reduce my hair breakage and now I see length retention. I still condition my hair (non silicone conditioner) after washing and then I put this on for 4-5 minutes. For me it still works incredibly well this way and I don’t suffer hair tangling or dryness. It’s my go-to leave in conditioner before I use keratase. I have 3c/4a fine, very soft hair.

The media could not be loaded. I am at the end of my second bottle now. For me is the best product on the market. Since using I have seen a massive difference in my hair texture and health. My hair is thick and frizzy. I bleach it every 10 weeks and I do that for years. This is the only product that retains moisture in my hair leaves it straighter and healthy looking. Dead ends are locked and not signs of damage. This was recommend by a colleague that couldn't stop taking how good it is and I agree. For my previous bottles I have paid around £25 for 50 ml, went to buy another bottle and is doubled the price. Honestly I think it's over-exagerrated £50 + a bottle!!!! I not sure I am willing to pay double.Will hunt for sales and stock up.I will 1000% recommend trying it.

I bought the mask and spray - disappointed as I felt the spray made my over processed bleach hair worse, increased breakage and the mask was clear and watery not like on the official demonstration of product, it was white and creamy even when rubbed on hands. Another customer commented on this having noticed the consistency change. No answer from K18 representatives. I believe olaplex ingredients have changed in their no 3 as it used to help my hair made it thicker and stronger, now it does nothing. Sometime I think companies like this wait until everyone is on board and then change the formula to a cheaper one? Whatever the case neither product helped my over processed bleached hair and both were extremely expensive. Coconut oil and Shea butter probably the best!

Love this mask. It makes hair look healthy and silky

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.

Authentic K18 products have a matte bottle finish, a specific air hole placement, and a printed lot number. This product is the real deal, as I checked all the above, and it passes!
