A few sociological theories have suggested that shaving of the pubic hair has to do with cultural trends spawned by certain hairless actors and actresses or even a misguided attempt at hygiene.
Pubic shaving actually originated in ancient Egypt and Greece, when prostitutes had to shave for both hygienic reasons and as a clear sign of their profession. Although female body shaving was established as the norm between 1915 and 1945, pubic hair removal did not actually gain a strong foothold until the 1980’s.
