Excellent product

5 stars out of a maximum of 5

I accidentally destroyed my hair with bleaching at home and had heard good things about this product but didn’t hold out too much hope. I was also hesitant due to the price but it has made my hair feel like hair again rather than chewing gum! Lifesaver.

Game changer for me, hair is healthiest it’s ever been. I also use the shampoo. Only works if you follow instructions, would advise watching a video.

Use leave in conditioner

4 stars out of a maximum of 5

I used a few times without adding a leave in conditioner and my hair felt like straw. Wait for 4 mins after application, don’t rinse out but do apply a leave in conditioner. Works best after repeated use over a few months

Wow

5 stars out of a maximum of 5

First time trying the product and I followed the instructions and I felt the difference straight away! I’ve recently had my hair bleached and it felt so thin and straw like and after using this product I can really feel the difference will definitely be buying more so worth the money. Makes your hair feel healthy and smooth

K18 is so expensive I was reluctant to try it but once I did I was hooked. It is absolutely miraculous in improving the state of damaged hair
