A male hair undercut is a popular hairstyle that involves shaving or closely trimming the sides and back of the head, while leaving the top longer. One common example is the classic "undercut," where the hair on the top is slicked back or styled into a pompadour.
The undercut is relevant because it offers a modern and stylish look that can be adapted to different face shapes and hair types. It is also relatively low-maintenance and can be styled in various ways. The undercut has been popular since the early 20th century, when it was worn by military men and later adopted by celebrities and fashion icons.
