Shaving (khurakamma) is the removal of head or facial hair by cutting it with a razor. The Buddha required monks to shave their heads and faces regularly and nuns to shave their heads. The main reason for this was to lessen the vanity that is usually connected with hair and perhaps also for hygienic reasons. Those with no hair cannot get lice and thus do not have to kill them. One of the eight basic requisites of monastic is a razor (Vin.II,133). Traditionally monks and nuns shave their heads before their hair gets more than one finger’s breadth long, which takes roughly a month.
