Incredible
I got this from my hair salon with an in salon pre-colour treatment . But will be purchasing from cult now I know they have it! I got the 5 ml. And have mid length hair. And lots of it. It was also very dry. I’ve got about 6 toes and counting from that small tube. So I’m a bit concerned by people saying the 5ml isn’t enough for one go. Try it sparingly first and then add more. It detangles and comes through easy. Too much and it’s a waste. You need less than you think It’s changed the texture and condition of my hair. My hair is now silky and soft. With better shine. It’s incredible.

This is the most amazing hair product. It has transformed my dry ends. My hair is also thicker,more shiny and easier to style. I will definitely purchase again. One pump is enough for my shoulder length hair. Truly a wonder!

Really good
I’ve been trying a few deep conditioning treatments and so many have been a disappointment. This left my hair really silky and healthy feeling, very impressed.

Great product
Worked as expected. I used for 5 consecutive wash days, only used 3 - 4 pumps at a time. My hair felt really soft afterwards. Going to purchase the bigger size bottle.

Wonder Product
Amazing wonder product for unmanageable hair. Pricey but a little goes a long way! I’ll never use anything else.

Ridiculously amazing
I've got between bra stap length and waist length light blue hair, it's been bleached since I grew it from a shaved head and had many colours and bleach baths. I've used K18 for 6 or 7 washes, just rebleached my roots and had *no* breakage. This stuff is expensive but the best thing I've put in my hair. I lose hardly any hair when I wash or brush it now, next to none really. I still use a leave in conditioner (Aveda) after I put the k18 in and leave it for 4 minutes. If you've got bleached hair, I can't recommend this enough. Don't bother with Olaplex, it's annoying to use (and didn't do much for me). This works far better. My hairdresser couldn't believe the condition of my hair when I saw her for a cut after 8 months. Best. Stuff. Ever.

Amazing
This was recommended by my hairdresser. I owe her big time. Used it as directed after using olaplex shampoo no4. What a difference. Highly recommend you give it a go.

Amazing!
This is magic! How such a tiny amount of product can detangle my super fine hair and leave it feeling like brand new hair is beyond words. Will be buying again

It works!
Echoing what a lot of others have said. This isn't a budget buy but it really does work! We are often sold an idea or a dream and lots of promises of the next holy grail product but many fail to deliver. Not this! Like many others, I prefer this to Olaplex. Hair looks healthier in one application and better each time you use it. My hair condition wasn't too bad. It is lightly coloured but showing signs of ageing and lower density. This seems to have turned the clock back and bought back a vibrancy that had been lost. Definitely will repurchase.

Amazing product, smallest size is too small for 1 use
Product is so amazing, the founders were also the creators of Olaplex before it was sold and the product truly does re-nourish the hair. I bought the smallest size as a tester initially but found that it was actually too small for a single use (I have long hair).
