The hair health allegations checks out!!!
I bought this after I kept hearing about k18. I was skeptical about this product due to the claims but after using it consistently for 1 month I can confirm my hair is softer , more moisturised and shiny . My hair texture overall has improved drastically ! A staple leave in in my hair routine

Recommend the small size
Hard to tell is this product actually works. There’s mixed reviews of how to even apply it. On the box it says not to condition your hair after use , which would effectively leave your hair super dry (specially for recently bleached hair). But then on their official website’s forum they say it’s ok to condition after the four minutes. I don’t notice a difference when I use it. Could be working , but could be a gimmick.
