Back in the 1950s a hair ad campaign ran with the slogan,

"Is it true...blondes have more fun?

If I've only one life...let me live it as a blonde!"

1. Men are more attracted to brunettes.

In a study by the University of Westminster and the Scandinavian Journal of Psychology, they discovered that while blondes may get more attention, men found brunettes more attractive. 

2. Dumb blonde jokes do not apply. 

Men perceive brunettes to be significantly more intelligent than blondes, according to a study by Weir and Fine-Davis.

3. Roots aren't a concern. 

"Brunettes have healthy locks with bounce and shine in abundance - this promotes confidence which makes it the number one choice for hair color," said Russell McGrath, hairdresser and operations director at Michael Van Clarke London.

4. Men feel more successful with a brunette on their arm.

In a massive poll, one in every five men admitted to feeling more successful with a brunette by their side. I mean, who can blame them?

5. Men assume brunettes earn more money. 

College participants were shown the resumes of three different applicants: blonde, brunette and red headed. They perceived the brunette applicant to earn a higher salary than the other females. 

6. Brunettes are seen as being less temperamental. 

When participants were shown images of the same woman in different colored wigs, brunettes were perceived as being less temperamental. 

7. Brunettes make better lovers.

Almost six in 10 (58%) of people say brunettes are better in bed. 16% chose blonde, followed by 12% in favor of black hair and 9% red hair, according to the Daily Mail. 

8. Brunettes are seen as marriage material. 

A study by Superdrug concluded that men believe brunettes make better wives. Input from 1,000 men found that 54% of respondents believe brunettes make the most ideal wives. 30% showed no preference and 16% chose blonde. The study also revealed men think dark haired women have more integrity and are deeper. 

So the next time someone says blondes have more fun, I would beg to differ!
