An Undercut hairstyle (aka âUndercutâ) is a type of menâs hairstyle that is comprised of a bowl cut and of a top part (i.e. the âbowlâ). The hair on the sides and back of the head in an Undercut is buzzed with a hair clipper and with a very short single clipper length.ecause of the above 4 main hairstyles for the Undercutâs top, you will always have plenty of hairstyling options to choose from once you have gotten the foundation for the Undercut (i.e. clipped back and sides of the head, while the top of the head is anywhere from 2 to 6 inches long).
