For these fat curls, side-part hair and apply mousse to damp hair from roots to ends. After you dry hair, roll hair in hot rollers starting at the temples. After the rollers cool, pull them out and style with your fingers or create big bouncy waves with a brush. Set with hairspray.
You can also curl straight hair such as Heigl's with a large-barrelled curling iron (see my favorite curling irons).
