Gentlemen prefer blondes, but in vain. Those who want to have frequent sex and hot nights should pay their attention to red-haired girls, according to the results of a recent research carried out in Germany.

Dr Verner Habermel, a professor from Hamburg has analyzed sex life of dozens of German women with different hair color. He divided the women in three groups: blondes, brunettes and red-haired and compared frequency of their sex life, levels of their sex drive, the number of sex partners and other important factors.

It turned out that red-haired women are much more sexually active than their peers with another hair color. Red-haired women have much more sex partners than other girls and they have much more sex contacts per month than brunettes and blondes. So women whose hair reminds of fire are quite up to their reputation.

The most interesting thing is that women, who dye their hair red become much hotter than their used to be. What is more, the decision to dye hair red means conscious or unconscious will to send a signal to men "I'm single. I'm searching for a new partner!"

Warning! The fact that your beloved blonde or brunette suddenly decided to dye her hair red is very likely to mean she is not happy with you and she wants to have another partner.
