Re-creating the style at home starts with a solid blow-dry. Use the concentrator attachment on your blow-dryer along with a slim round brush to style hair forward in a downward motion. You don't want to create too much volume. You can use a half-inch flat iron to refine the pieces around the face. Resist the urge to curl under, and keep the ends stick straight or even flipped out a touch. Even though it appears to be a basic middle part, a zigzag line is the key to getting Jennifer's chunky, layered look. Start by using the long end of a rat-tail comb in the centre of the hairline, and part right to left in a Z shape. Finally, finger-comb hair with a dollop of pomade.
