If your hair is looking limp, flat, and a little greasy, buy you are out of dry shampoo, grab some oatmeal!!! Put a handful in a sealed plastic bag. Pound this down to a fine powder with a heavy kitchen tool (a rolling pin will work!). Now, sprinkle some onto your scalp massaging with your fingers, then brush out the excess. The powder will lift the roots and plump your hair giving a fuller appearance.
