Most hairstylists urge you to go with your natural part, which is where your hair falls on its own. But you don't have to, if you find a different look that works for you. For example, if you have a heart-shaped face, you should avoid a center part as it will make your face look rounder. If you have a round face, you should try a side part. Sweep your bangs or any long layers diagonally to the side. This breaks up and softens a round face, and also accentuates your cheekbones. If you're looking to add some height and volume to your hair in order to lengthen your face, try parting your hair on the opposite side of your natural part.
