Women with blonde or fair hair are more aggressive and determined to get their own way than brunettes or redheads, according to a new study.
Researchers claim that they are more likely to display a “warlike” streak because they attract more attention than other women and are used to getting their own way.
Women who dye their hair blonde quickly take on these attributes, experts found
The findings about aggression are contained in research by the University of California, to discover whether women who are judged more attractive than others are also more likely to lose their tempers to get what they want.
“We expected blondes to feel more entitled than other young women - this is southern California, the natural habitat of the privileged blonde,” said Aaron Sell, who led the study which has been published in the Proceedings of the National Academy of Science.
“What we did not expect to find was how much more warlike they are than their peers on campus.”
The researchers believe this is a useful measure of how far women are prepared to fight for their own interests.
The study, which examined links between confidence and aggression, involved 156 female undergraduates.
It showed that blondes were more likely to be treated better than other women and were more willing to “go to war”.
However, they were less likely than brunettes or redheads to get into a fight themselves - possibly to ensure they preserved their looks.
The research did confirm one theory: when male students were asked to rate the attractiveness of their female counterparts, blondes gained the highest scores.
