Common belief and also research carried by social and evolutionary psychologists show that men prefer women with blonde hair (Rich & Cash 1993). However, the reason has not been completely and definitely explained (e.g. Frost 1989; Ramachandran 1997). In three laboratory experiments it was tested how hair colour influences on the perception of a woman's age and physical attractiveness. The results showed without doubt that blonde hair is, irrespective of other indices of psychical attractiveness, a rejuvenation factor which has a positive impact on the attractiveness of a woman at given age (above 25 years old). No essential relationship was found out between the age of a man and his preference for a specific hair colour. Do men prefer blonde women? The results showed that men prefer women with blonde hair but only woman at given age (above 25 years old). The results were discussed in terms of evolutionary-based sex differences in reproductive strategy.
