Also known as: ツーブロック, 刈り上げ
A hairstyle in which the sides or back of the head are shaved or buzzed short, while the hair on top is kept long. The long portion may be swept to one side, slicked back, or left to hang in front of the face.
The undercut was first popularized during the 1910s to 1940s, before becoming fashionable again in the 2010s among both men and women.
