Men think brunettes take better care of their appearance, make better cooks and are more proficient at keeping the house clean, the study by a UK-based beauty and health retailer found.
The study of 1,000 men found 54 per cent would choose a brunette to be their wife, 16 per cent would opt for a lady with fair hair, while 30 per cent don't have a preference.
And when it comes to getting a girlfriend, 48 per cent chose girls with brown hair, one in four chose blondes and 27 per cent said neither.
"Men obviously have their opinions about the colour of women's hair," said a spokesperson for Superdrug.
"But our sales tell us that when it comes to hair dye women are more likely to change their shade when they see a celebrity switch shade than any other reason. This research turns our hair stereotypes on their heads," the spokesman added.
