Read the 1 Star reviews !

So not worth the money. I was in a hurry and only looked at top few reviews. If I’d scrolled down I would have gotten a better idea of this product. Not thick, no smell, doesn’t do much for my hair. I even tasted it, thinking it was water. Not sure of the hype at all.

Good

I like this. It smells good for sure. I don’t think it’s worth to buy. I would go for kerastas oil. I’ve seen way better results. Save your money. K18 mask is worth it, but I haven’t seen notable results with this.
