Historically, working-class people's haircuts have tended to be practical and simple. Working-class men have often shaved their heads or worn their hair close-cropped, and working-class women have typically pulled their hair up and off their faces in simple styles. However, today, working-class people often have more elaborate and fashion-conscious hairstyles than other social classes. Many working-class Mexican men in American cities wear their hair in styles like the Mongolian (shaved except for a tuft of hair at the nape of the neck) or the rat tail (crewcut on top, tuft at the nape), and African-Americans often wear their hair in complex patterns of box braids and cornrows, fastened with barrettes and beads, and sometimes including shaved sections or bright colour. Sociologists say these styles are an attempt to express individuality and presence in the face of social denigration and invisibility.
