In all, 52 per cent of men said they would rather marry a dark-haired woman because they are more dependable and sensible - whereas only 18 per cent think blondes would make good wives.
In the poll of 3,000 men, 36 per cent said blondes were the sexiest women, while 31 per cent thought brunettes were sexier.
A mere 18 per cent of the men thought a blonde would make a good wife, reports the Daily Express.
Hairdresser Andrew Collinge, whose company commissioned the poll, said: "This shows just how much men judge a woman by their hair colour. It is surprising - I thought men were more modern than this."
Almost 37 per cent said women with fair hair were the most fun, but dark-haired women were considered the best long-term option, with more than half of all the men saying they were the most trustworthy.
The research also revealed that 33 per cent of males have a particular hair shade they always go for, with 44 per cent saying they are more attracted to brunettes.
