Skinhead culture developed in the first half of the twentieth century when working class young English men would dress in their finest on weekends and go to the local dance halls, largely owned by West Indian immigrants. It has been proposed that the shaven head is due to the fact that many of them were employed at loading docks, and sacrificed their hair to protect against lice. The mixture of rough-and-tumble middle class men and the reggae music resonating from the dance halls gave rise to a population of tough, shaven-headed ska fans. The young men were inspired by songs about the Jamaican rude boy lifestyle. Many people are surprised to know that at one time, there was a large population of black skinheads. As time progressed, skinheads have developed factions, including neo-nazis and anti-racist sharps.
