Did you ever notice how men often start growing beards and losing hair at the same time? Well, there’s a scientific solution for that, and it’s called dihydrotestosterone. This chemical promotes beards and balding, and varies seasonally, often creating bushier hair in warm summer months. Aside from science, what drives a man to grow a beard?
According to this Online PhD Infographic below, growing a beard has always been a sign of manliness, and your 13-year-old brother would probably agree. Scientists believe that beards were used for protection, intimidation, and warmth back in prehistoric times, and some might argue that’s still true today. Beards were a sign of honour, until Alexander the Great decreed that soldiers could not have beards, for fear that enemies would pull them in battle. Since then, beards have fallen in and out of favour for centuries, based on trends, and apparently, on the marriage market.
Women find men with beards 2/3rds less attractive than their clean-shaven counterparts. Research shows that women aren’t as keen to choose a beard-laden partner, and when the marriage market is in poor shape, men seem to shave to make women feel safer. Apparently, beard intimidation keeps adventurous women away, so maybe keeping your beard is a good way to weed out the weak partners!
