Women shave their heads for lots of different reasons, often professional

Historically, shaved heads have had practical purposes. In ancient Egypt men and women shaved their heads and wore wigs because it helped protect against lice, among other things.

We may never know why Britney Spears shaved her head. But she's hardly the first female celebrity to do it. Or even the first singer. The difference is that most of those women did it for their art.

Forcing a woman to shave her head also has been used as a means of control and humiliation. Thousands of women lost their hair in Nazi concentration camps.

These days, a shaved head is often a sign that a person is undergoing chemotherapy, which can cause hair loss, or is making some kind of political or militant statement, said David Shmagin, a stylist and the manager of Robert Kree salon in New York, where clients include Drew Barrymore and Sarah Jessica Parker.

"It's a strength thing and to show they don't have to care about it (their hair) because they are focused on other things," Shmagin said, of women who cut their hair voluntarily.

Remember the nearly bald Sinead O'Connor, tearing up a picture of Pope John Paul II on live television in 1992, exhorting viewers to "Fight the real enemy"?

Most celebrities who go without hair do so when the script calls for it.

Natalie Portman, who had long brown hair, shaved her head for V for Vendetta, which was released last year. She kept the hairstyle for several months and debuted it at the Cannes Film Festival during the premier of Revenge of the Sith, in which she played Darth Vadar's love interest.

Demi Moore shaved her head on camera while depicting the first female Navy SEAL in G.I. Jane in 1997. Sigourney Weaver shaved her head for Alien3 in 1992.

Persis Khambatta made bald beautiful as Lt. Ilia in Star Trek: The Motion Picture." And Canadian supermodel Eve Salvail graced the cover of ELLE magazine and the world's top runways (including for Chanel and Versace) with no hair.

Musicians have been more likely to shave their heads as personal fashion statements.

Erykah Badu shaved her head in 2001, saying she wanted to "make room for new things." India. Arie did it before the 2003 Grammy awards, explaining that her shaved head indicated "spiritual cleansing."

But unquestionably, bald women have not earned the same level of acceptance as purposely bald men have in American society.

Boston hairstylist Mario Russo of Salon Mario Russo said that in 26 years he has never had a request from a woman to shave her head, unless she was undergoing chemotherapy.

Bald women are still fair game to make fun of, too.

In a Seinfeld episode, George tests out his new toupee on a blind date, yet rejects her when she turns out to be bald.

Stylist Shmagin said he suspects that Spears' haircut was partly in reaction to her recent split from husband Kevin Federline. Still, he said Spears "had been torturing her hair for so long," wearing hair extensions and recently reportedly dying her locks herself. She may find that when her hair grows back, it looks better than ever.

Shmagin said he doesn't think that Spears' haircut will be emulated since no one shaved her head after actress Portman did it "and she pulled it off well."

"No one wants to be like Britney, and that's so sad. We can all laugh and joke but I think once she shaved her head you really start feeling bad for her. Sweetheart, what happened?"
