Maybe blondes do have more fun: U.K. researchers say that women who dye their hair blonde are more likely to ask for a raise, initiate a romp and register a complaint over poor service.

In a Clairol-commissioned study, researchers from Nottingham Trent University found those who color their hair a lighter hue experience confidence boosts and feel less inhibited. About half reported feeling more "impulsive, sexually exciting, rebellious, creative, attractive and able to deal with criticism" after a dye job. About 80 percent chose a blonde shade.

While stereotypes about blondes having more fun have persisted for decades, research is mixed on whether or not gentlemen really prefer them. In a 1985 study, New York University scientists found no hair color bias when measuring how often men stopped to help female pedestrians, half of whom were blonde and half of whom were brunette.

But a 2007 article in "Psychology Today" pointed to evolutionary logic behind men wanting to date Cameron Diaz lookalikes. Many people, the authors said, have blonde hair as children, but then become brunettes in adulthood. Men seeking out blondes may be "unconsciously attempting to mate with younger (and hence, on average, healthier and more fecund) women." Whoa.

Tell us: Do you prefer being blonde?
