Knowing your face shape can also help you determine the most flattering hairstyles and haircuts for your face. For example, if you have a round face shape, a layered haircut can help add dimension and create the illusion of a more angular face. Similarly, if you have a heart-shaped face, a side-swept bang can help balance out a wider forehead. Additionally, understanding your face shape can also help you choose the right accessories, such as earrings or hats, that will complement your features. Knowing your face shape can also aid in contouring and highlighting techniques to enhance your natural features.

The oval face shape is considered to be the most versatile as it can pull off a variety of hairstyles and makeup looks. This face shape is also known as the "ideal" shape as it is well-balanced and symmetrical. Oval faces are also characterized by soft, rounded features and a slightly narrower chin. Some common hairstyles that suit this face shape include long layers, side-swept bangs, and a middle part. Makeup-wise, oval faces can experiment with different looks, but it is recommended to highlight the cheekbones and jawline to enhance the natural symmetry of the face.

Square face shapes are characterized by a strong, angular jawline and a forehead, cheekbones and jawline of equal width. This face shape is often seen as strong and powerful, and is often associated with a more masculine look. People with square face shapes may have a longer nose, and their eyebrows may appear to be more angled. To flatter this face shape, people should opt for haircuts that soften their lines, such as long layers and side-swept bangs. Makeup should be used to contour the face, as well as to bring out the eyes and lips. Accessories such as scarves and hats can also be used to draw attention away from the angular jawline. Celebrities with square face shapes include Keira Knightley, Angelina Jolie and Olivia Wilde.
