I can remember one of my first experiences with dry shampoo. I was working in another city, living with my ex boyfriend and his family (hello if you're reading!) and I was at work at the time of trying it. I didn't know how to use it. I'm serious. I didn't know if I had to rub it in, or brush it out, or whatever. It's embarrassing to look back on. I might call myself a little bit of a pro now.
