Curtained hair or curtains is a hairstyle featuring a long fringe divided in either a middle parting or a side parting, with short (or shaved) sides and back.
Origins
The Baiyue (1st millennium BCE) appeared to keep their hair short and curtained in this style, unlike many other primitive peoples who had longer 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. Despite the fire risk, much paraffin wax was used to keep the hair in place.[1] Other gangs who favored this haircut were the Scuttlers of Manchester and the Peaky Blinders of Birmingham, due largely to the disadvantage caused by longer hair in a street fight.[2]
