It’s good

Hair felt so much stronger anf healthy after using, yes it’s expensive but you don’t need much so the bottle will last a while.  I am impressed by this bottle of miracle for hair

Disappointed

1 stars out of a maximum of 5

I was excited to try this and viewed it as a potential replacement for Olaplex no.3, however am very disappointed with the results. I should preface my review by saying I have VERY knotty, fairly long hair that is highlighted and prone to frizz, as such I was sceptical about not using conditioner - after looking at FAQ’s on the brands website I did end up using conditioner for 2/6 washes as per their suggestion. I do not feel that this helped my hair at all and feel I have definitely noticed more breakage and split ends than usual, since using this product- I also spent an extremely long time detangling my hair. Whilst I do colour my hair, I have a good routine and rotation of products and have never really noticed any substantial damage until this point- I rarely write reviews however was really excited to try this product and continued using despite my better judgment so I could complete the full six treatments as recommended by the brand- I think I’ll be heading the hairdressers for a trim and restocking my Olaplex!

Good stuff

I was dubious about the fact you don’t use conditioner with this product! But my highlighted hair felt lovely after using this. Small bottle for the price but you only need a small amount.

Incredible

5 stars out of a maximum of 5

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

5 stars out of a maximum of 5

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

5 stars out of a maximum of 5

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.
