Phauxhawk

Hairstyle inspired by the traditional headdress of the Mohawk tribe - according to a 1939 Hollywood movie starring Henry Fonda. This style was popularly associated with the Punk Rock subculture of the late 1970's and early 1980's.

Today it has entered the main stream as a hairstyle defined by a strip of long hair down the middle of the wearer's head, flanked on both sides by shorter hair.
