The undercut is a hairstyle that was fashionable from the 1910s to the 1940s, predominantly among men, and saw a steadily growing revival in the 1980s before becoming fully fashionable again in the 2010s. Typically, the hair on the top of the head is long and is often parted on either the side or center, while the back and sides are buzzed very shorter or shaved.[1] It is closely related to the curtained hair of the mid-to-late 1990s, although those with undercuts during the 2010s tended to slick back and top gelled up the bangs away from the face.
