We may think women with blonde hair have more fun, but stereotypes aren’t science. Clichés suggest that blondes are less capable than brunettes, but the real deal is that blondes have higher salaries and richer husbands.

This study was based on a large U.S. survey, including interviews with 12,686 Caucasian women, yearly or biennially from 1979-2006—a total of 27 years. The data showed that natural blondes equaled other women on test scores and education, but their wages were 7 percent higher. (That equates to roughly one more year of education.) Blondes’ spouses also earned 6 percent more than other hubbies.

Of course, money can’t buy you love (or happiness), but according to this study, a dye job might buy you a bonus.
