What to Tell Your Barber: Keep the sides short—1/2″—and clean around the ears and back. Keep at least 2″ on top for the height needed to style. How to Style It at Home: Clean and classic, this look requires an easygoing product like a cream. Apply with hands, raking through from front to back and use a comb to create a clean side part. Then take the comb and, starting at front (roots), comb and lift up and back for some height.
