On the contrary to what society thinks, blondes are not stupid and science seems to be with us on this!36% of men prefer to sleep with blonde women, while the percentage of the men who prefer a brunette is 30%.This can bring both advantages and disadvantages, however for women, it looks more like an advantage. Scientist claim that blonde women look 23 until they turn 45. (Really now?)Don't interpret this as a shallow expression like they are sexier, they like shopping more, etc. It is a research-proven fact that blonde women's estrogen levels are higher than brunettes.Smaller nose, softer skin, less body hair etc.Nope, we aren't claiming this, research does. Blonde women are perceived most as 'unattainable' and the brunettes are perceived as easier. The jealousy is quite normal in this situation.Because men died quite easily during wars and hunting, women were competing to attract the few numbers of men left. Blonde women won this competition most of the time. That's why it is also pretty understandable that this has been coded in our genes.According to research conducted by Cornell University, brunette women, even though they were sexier and more attractive than the blondes, did not get as many tips as blonde women did.Next time you go out, you will see that the women who have the most fun, laugh the most and are the most joyful are the blonde women. And it is also scientists' statement that women who don't go out or like partying, go through a shockingly big change after they dye their hair.
