K18Biomimetic Hairscience Leave-In Molecular Repair Hair Mask

I've been using k18 for about 18months now.Truly amazing product. It's not a one time fix product but the longer you use it, you really see the effects its having on your hair.Will continue to use this

So I have really curly/ coarse hair and I straighten it so often that the front especially the fridge literally just stays straight.I initially bought the 50ml and I wasn’t convinced it would moisturise my hair especially if I just shampoo with no conditioner as the instructions say because my hair NEEDS moisture and is low porosity. But let me just say that wow it does moisturise and it leaves my hair so juicy, I add my usual products after 10mins of air drying. I haven’t seen too much repair of the curls at the front but it has really helped with my bleached ends which have split ends.I have A LOT of hair so I need to use way more than the 2 pumps per section and this bigger bottle definitely helps with that. Very expensive but so is salon visits. Also, the bigger bottle DOES cream up after rubbing so I’m not sure why other reviews say it’s a different formula. Very happy with the product but wish it was less expensive. Hopefully it brings rest of my curls back but ngl it has just encouraged me to continue straightening without fear of catastrophic damage haha. Love it!

After frying my hair with bleach it was snapping off and so dry, I’d tried Olaplex treatments prior to this and the K18 blows it out of the water. Results are immediately obvious, my hair looked fuller and smoother after just one use. As my hair was in such a bad state I used this after every wash for 2 months along with their shampoo and my hair is finally starting to regain health. Impressive stuff!

I was hesitant what with the price of this but was recommended by a friend.I have very long bleached platinum hair, and whilst it’s in decent condition it obviously suffers damage. After using this for 6 uses there is a very noticeable strength to my hair that wasn’t there before. After the first use the improvement in silkiness was there too, but it really took those multiple uses to do its thing. Won’t go without it now!

Absolutely gutted to have spent nearly £60 on a product that i can't get out of the bottle. Not pumping any product out at all, Did contact seller unfortunately no response.

I love this product so I bought this large size. When it stopped pumping I assumed it was finished but I suspected there would be enough in it around the sides to get a good few more applications so my husband took a saw to the package. To my shock it had at least one third left, the pump just didn’t pump any more. Also I was annoyed to spot the bottom 1/4 I of the packaging is blank. The rigid plastic makes it hard to guage how much is left. I have had to cling film over the 2 halves and get an applicator to use. So be aware and get every scrap out it is not cheap.

This is a really good product. My hair is bleached and breaking; this has really helped to restore strength and shine.A little goes a long way, so good value despite the high purchase point.

A small amount goes a long way to drastically improving hair quality - ive tried numerous products over the years as I’m a swimmer and this is definitely the best! It also saves time as you don’t have to condition your hair on the shower - I could immediately see the difference. My hair is medium to long length, coloured blonde and I swim 4/5 times a week. It’s of medium thickness.
