An uncovered head is symbolic of the removal or denial of a legitimate higher authority and all of the protection that authority might have conveyed. Shaving the head and face (or the hair falling out) is a dramatic way to uncover a head. (See #leviticus 13:29-59.) Tzara'at (Hebrew for leprosy) of the head and beard might indicate a sin of prideful Lashon Hara (evil tongue) against authority. Pathological rejection of rightful authority breaks the bonds of community and, like tzara'at, must be quarantined.
