One of the best hairstyles for round faces is long hair with gentles waves and side-swept bangs, according to About.com. Longer hair helps to elongate a round face, while longer bangs create angles to complement the face shape. Waves in the hair minimize the face's rounder shape.
To best complement a round face shape, hair should fall at least a few inches below the chin, and layers should hit above the ear lobe. Short bob haircuts that fall at or above the jawline should be avoided, as they make the face appear even rounder. For those adding curls to their hair, the curls should begin at the lips or lower, as curls close to the face make a round face appear even wider.
