Loot at Emma Watson Haircut
When it comes to hair, thicker is definitely better. An easy way to create instant volume at the crown is to do away with a full-length part. Instead, brush hair on top back to add height a la Emma Watson.

Get her look: Add volumizing mousse to the roots of damp hair. Blow-dry with a large paddle brush, giving a little root lift and rolling the brush at the ends. Blow-dry sections at the crown back. Once dry, take a one-inch section at the front and use a bobby pin to tuck it behind the ear.
