That old adage about gentlemen preferring blondes to brunettes may actually be true, if one new genetic study is to be believed.
Researchers at King’s College London conducted a study on genetics and hair colours with the results throwing up an interesting theory when it comes to women.
The study showed how women are twice as likely as men to be fair haired. According to the research, blonde women who are lucky in love tend to pass this physical characteristic genetically.
Therefore, the fact there are considerably more blonde women than men is proof that men prefer this hair colour.
Or at least that is what has been argued in this new study, published in the journal of Nature Genetics, which identified 111 new genes that affect hair pigmentation.
Data from 300,000 adults was analysed to find out which hair colours were most prevalent, with the results highlighting a drastic contrast between men and women.
According to the study, men are more likely to have darker features, whereas blonde genes were more active and common among women.
Professor Tim Spector, the researcher behind the study believes that this is affected by sexual preferences and the fact women prefer tall, dark and handsome guys compared with blonde women.
He said: “We found that women have significantly fairer hair, which reflects how important cultural practices and sexual preferences are in shaping our genes and biology.
“Men are three times more likely to have black hair than women.
“It could be for evolutionary reasons, as blonde women are more likely to be successful with men and dark-haired men are more likely to be more successful with women.”
