What are the best styles for different face shapes? Oval: Every hairstyle works. Round: Hair below the chin with a center part like long one length hair. Square: Hairstyle should soften the sharp angle of your jawline -- think face-framing layers. Triangular: Any style that narrows your chin and widens the forehead, like a boxed bob. Heart: Softer curlier style. Oblong: Style that adds width and fullness to the sides of the face, mid to long length with shorter interior layers.
