Put both ingredients together in a shaker bottle, and shake bottle vigorously. Shake about a half teaspoon onto your hand. Rub your hands together to spread it around your hands and fingers. Pat the areas of your head you want to shampoo with your hands. Tousle your hair around, as you rub in the dry shampoo. If you see any spots of dry shampoo, brush it out with a brush. That's all. You're done.
