I second that!
Uh, yea, it was you I was worried about. You and a friend of mine. I personally don’t have that problem.
And I will continue to deny I have that problem until the last 4 foot long hair, that I carefully coil around my dome, falls out.
In a study by Muscarella and Cunnhingham, males and females viewed 6 male models with different levels of facial hair (beard and mustache or none) and cranial hair (full head of hair, receding and bald). Participants rated each combination on 32 adjectives related to social perceptions. Males with facial hair and those with bald or receding hair were rated as being older than those who were clean-shaven or had a full head of hair. Beards and a full head of hair were seen as being more aggressive and less socially mature, and baldness was associated with more social maturity. A review of social perceptions of male pattern baldness has been provided by Henss (2001).
Other evolutionary hypotheses include genetic linkage to beneficial traits unrelated to hair loss and genetic drift.
Baldness is not only a human trait. Some other primates, such as chimpanzees, stump-tailed macaques, and South American uakari show progressive thinning of the hair on the scalp after adolescence. Adult stump-tailed macaques, in fact, are commonly used in laboratories for the testing of hair-regrowth treatments.
