Why Monks Had That Haircut

What was the deal with that monk haircut? Known as “tonsure,” the typical monk hairstyle has many variations throughout religions. The particular hairstyle worn by Christian monks has its own variations and controversies as well. Three different types of tonsure were popular: a coronal tonsure, a Pauline tonsure, and a third Celtic tonsure that came to represent the differences between the Roman Catholic and Celtic Catholic church.
