Short hair refers to any haircut with little length. It may vary from above the ears to below the chin. If a man's hair reaches the chin, it may not be considered short. For a woman, however, short varies from close-cropped to just above the shoulders. This varies from culture to culture, in more traditional societies in Eastern Europe, Asia, and the Islamic world, short hair on women means anything shorter than chest length with chest length to elbow length being considered medium-length. However, among more progressive societies with far less structured gender norms, the classic bob is considered medium-length with "short hair" referring to pixie cuts and similar hairstyles. Different styles of short hair include the bob cut, the crop and the pixie cut.
