Really expensive
It’s very pricey and I haven’t seen a huge change yet but I think you’ll have to use it consistently to see results

Expensive
My hair did feel nice but I’m not sure I would repurchase with the price tag. My hair is fine so feels a bit more weighed down

Got compliments after I used this mask
I'm happy I tried this leave-in hair mask. After the first use I got compliments for my hair style. I used this mask together with K18 hair oil and loved how easy I could then style my hair.

The best!
Every single time I’ve used K18 I’ve been annoyed that it really is worth the money for such a seemingly small amount — it really does drastically improve hair texture and overall health. I couldn’t go without it now.

Expensive but had really helped
I had damaged hair from bleaching and using this consistently for about 6 months has really helped both the length and health of my hair. Though it’s expensive I really feel it’s worth it!

Amazing
I’ve been using this for a couple of years now and I love it, I had incredibly damaged hair and thanks to this it’s completely healthy and I’m able to do what I want with it. A little bit goes far and it’ll feel horrible if you use too much but used as directed it’s one of the best things you can use for damaged and/or coloured hair
