A bob cut, also known as a bob, is a short to medium length haircut, in which the hair is typically cut straight around the head at approximately jaw level, and no longer than shoulder-length, often with a fringe at the front. The standard bob cut exposes the back of the neck and keeps all of the hair well above the shoulders.

A hairstyle, hairdo, haircut or coiffure refers to the styling of hair, usually on the human head but sometimes on the face or body. The fashioning of hair can be considered an aspect of personal grooming, fashion, and cosmetics, although practical, cultural, and popular considerations also influence some hairstyles.
