Hair styles are an important part of fashion and personal expression. Afros, dos, bobs, updos, and pageboys are all popular hair styles. An afro is a hairstyle characterized by a large, often rounded mass of naturally curly or kinky hair. A dos is a hairstyle that is short on the sides and back and longer on the top. Bobs are a classic hairstyle that is cut straight around the head at about jaw-length. Updos are a hairstyle where the hair is pulled up and away from the face. Pageboys are a hairstyle where the hair is cut in a straight line around the head, just below the ears.
