קָרְחָה qarchah "baldness" the only voluntary baldness in the Bible is the shaving of the head as a sign of mourning (cf. Am 8:10).
The Bible seems ambivalent to this custom (cf. Lev 21:5; Dt 14:1). Such shaving of the head was associated with other (more extreme) forms of mourning in pagan cults, as when worshipers joined Anat mourning for Baal.
