I like it!

I used about 6 drops on my long hair and was surprised to see it actually did something for my hair with so little. my hair looked smoother with it on. I haven't gotten to test how it works with humidity which triggers my frizz

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.
