Bowl haircut

A bowl cut, or bowl haircut, is a simple, plain, and short haircut where the hair is cut with a straight fringe on the front and the rest of the hair is the same length all the way around or is cut short on the sides and back. It is so named because it looks as though someone were to place a bowl on the head and cut off or trim all of the hair to a very short length. A bowl cut is also known for being a cheap and easy haircut often sported by children, typically in less developed countries worldwide.

Historically, the bowl haircut was popular among common people of various nationalities as an easy and relatively neat cut by a non-professional. Indeed, it was done by putting a cooking pot of a fit size to the level of the ears, and all hair below the rim was cut or shaved off. In some cultures it was a normal type of haircut. In other cultures the bowl cut was viewed as an attribute of poverty, signifying that the wearer could not afford to visit a barber.
