Unable to use?!?
Can’t really say if this works or not. Only used it twice before the sprayer stopped working. This is crazy expensive to have it not work after a few uses. What am I supposed to do with it now?!

Trust me it’s worth it.
First of all, anyone saying anything negative about this product in the reviews is using it wrong. I have a lot of fine hair so my hair gets super greasy super fast. Not only does this make my hair look freshly washed, it prevents my hair from getting anymore greasy even going into the next day. I’m not obsessed with the smell but for how good it works I don’t care. You have to start with small sections and work in into the roots WHILE IT IS STILL WET. It does make your hair feel a little dry when you touch it but I’d rather my hair feel a little dry and look fresh than have it look and feel like an oil slick. I’ve had my bottle for over a year and I rotate it with another dry shampoo and I still have not run out. Bottom line, rebuying this for life it’s worth the hype 100%.
