What is a beard?

A beard is the collection of hair that grows on the chin, cheeks, neck, and upper lip of humans, typically men. Beards develop during puberty due to increased levels of testosterone, and their growth rate and fullness can vary greatly among individuals. Throughout history and across cultures, beards have been associated with masculinity, wisdom, status, and sometimes religious significance. Many people choose to style, trim, or groom their beards in various ways for personal or cultural reasons.
