Definitely not for me
I have thin, damaged hair from bleaching and this product only made it worse. I really wanted to like this product, as I’ve heard so many good things about it, but it’s just not for me. It actually made it break off even more. I hope this review reaches people with the same hair type - As I definitely wasted my money on this.

This is probably what you're missing
I actually really like this. It makes my hair soft, which I loveeee. No product has kept my hair soft for days! Truly was impressed. I also have coily hair. Have tried it on my color treated and not color treated hair (I cut my hair often)
