I don’t wash my hair a lot. Like twice a week or so. I just don’t like doing it, and I don’t like how dry my hair and scalp get if I wash it every day. This dry shampoo is amazing!! One little bottle of this lasts almost a year – and that’s with mini-Amateur nicking it from my drawer, too! I love that it doesn’t contain the weird ingredients that the grocery store aerosols do. Like butane and propane. What in all the world do I want that on my head for?? This stuff. Even fixes gym hair. Give it a try!! (they also make one for dark hair!)
