8. Hair color
Scientists from France have conducted research that showed which women are invited to dance in nightclubs more often: blonde-haired, brown-haired or red-haired.
The conclusion was that men invite blondes more often than others. The second place was taken by brunettes, and red-haired women were the least attractive for men.
The scientists thought that this was not due to the color itself, but how good the hair color looks together with the skin color. So, the skin color of the majority of the red-haired women was found the least attractive of eight skin colors.
