After winning a coveted "Skinnies Award" for getting too much sun, pop sensation Britney Spears felt she had too much of something else: her hair. Opting for an extremely surprising extreme makeover, Spears sheared herself bald in what some cable pundits think is a sign of mental instability. Yet Spears is not the first high profile chanteuse to go hairless. Irish siren Sinead O'Conner has appeared shaved and sultry for most of her career. Rocker Joan Jett tried the cue ball look when she starred in a theater version of "The Rocky Horror Picture Show." Soul sister Erykah Badu has been seen hair-free on tour starting in 2001, stating that she wanted to “make room for new things.” It is possible that there may have been a medical reason for Badu's hair loss, such as overtreatment of hair or alopecia areata. Finally, Melissa Etheridge proudly displayed her pate while battling breast cancer. So will Britney establish baldness as a new fashion trend? Since most women prize their locks as a sign of health and beauty, it seems unlikely that impressionable teens will start shaving their scalps. Spears has since been seen sporting a blond wig, so we doubt the "Oops, I did it again" girl will cut her hair in the future.
