FOR STRAIGHT VOLUME: Split your hair into three large sections, working from the bottom to the top of your head. Use a blow-dryer with its concentrator attachment. Work a round brush underneath 1-inch sections of hair as you run the dryer over the top (holding the nozzle at a downward angle). Make sure to create tension with the brush so your hair is taut.
FOR TOUSLED TEXTURE: Air-dry your hair. As its drying, twist hair section by section and then gently scrunch in an upward motion.
