A hairstyle, hairdo, or haircut refers to the styling of hair, usually on the human scalp. Sometimes, this could also mean an editing of facial or body hair. 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.
The oldest known depiction of hair styling is hair braiding which dates back about 30,000 years. In history, women's hair was often elaborately and carefully dressed in special ways. From the time of the Roman Empire until the Middle Ages, most women grew their hair as long as it would naturally grow. Between the late 15th century and the 16th century, a very high hairline on the forehead was considered attractive. Around the same time period, European men often wore their hair cropped no longer than shoulder-length. In the early 17th century, male hairstyles grew longer, with waves or curls being considered desirable.
