Smartcookie- the trick is to do it from arms length to ensure that you get an even mist that evenly coats your whole face (also, I do every possible spot, more than once 😉 )
mischeifmaker – there is a product called Oscar Blandi Dry Shampoo. It is similar to baby powder but it doesnt make your hair grey and it smells great and since its shampoo it freshen your hair as well.
