Curtained hair

For the first couple of decades of the 20th century, a longer variant of the undercut was popular among young working-class men, especially members of street gangs.

In interwar Glasgow, Neds (the precursors to the Teddy Boys) favoured a haircut that was long on top and cropped at the back and sides.
