Review of Batiste Rose Gold Dry Shampoo 350ml

My wife swears by this stuff, she reckons it's better than any other dry shampoo out there. I don't think that it is particularly good for one's hair though, especially using it as frequently as she does. Quite pricey too, so she usually stocks up when it's on special (at Chemist Warehouse, often) or on half-price.
