Maybe…maybe not
I’ve watched & read a lot on this line to ensure I’m using it correctly. I don’t think it’s anything special and I feel like I have to wash my hair more often when I do use it; must not be for my hair. I think it smells like BO.

A must-have
I always have a few shampoos in my shower and this is always a staple. I have oily hair so when I really want my hair to be extra clean but not striped, I use this.
