The best hair repair treatment I have used

The best hair repair treatment I have tried and I have tried many. It is very expensive but a little goes a long way.

K18

The best hair treatment. Prefer this to Olaplex No 3 as easier to use. Feel results after the 2nd or 3rd use.

Wow

I had such broken hair around the front of my face from going blonde. This has really helped promote growth and works so well!!

Staple for anyone with damaged hair

K18 is unbelievable! I’ve been using it since December and my hair is so much stronger, smoother and healthier!  I’ve had so many compliments about my hair since using this. It’s expensive but if, like me, you can never seem to make your hair look good no matter what you do, this is the product for you.  If you don’t like how it makes your hair feel, leave it in for the recommended 4 minutes and then follow it with your regular conditioner.

great product

this is so good. i was skeptical so i got the small size and i’ve used it approximately 20 times and my hair feels great and will defo be getting the bigger one

Okay

I love when products have smaller sample size to try, however in this case I didn’t notice a huge difference so I think the bigger bottle would be required

Worth the £££

This product is so expensive but definitely worth it! I’ve used Olaplex no.3 for years and recently switched to this product and I’m amazed at the difference. I can instantly see and feel the difference in my hair.

Saved my bleached hair!

This stuff is amazing. You have to dose it right and not use too much (no more than 3 x 5 pence sized blobs) and make sure you hair is really towel dried well. It feels awful when you first apply but once you leave it for the 4 mins, it feels so soft and hydrated. My bleached hair has finally stopped snapping!
