Leviticus 14:8-9 - The Seven Days Of Purification
8 "He who is to be cleansed shall wash his clothes, and shave off all his hair, and bathe himself in water; and he shall be clean. After that he shall come into the camp, but shall dwell outside his tent seven days. 9 It shall be on the seventh day, that he shall shave all his hair off his head and his beard and his eyebrows, even all his hair he shall shave off. He shall wash his clothes, and he shall bathe his body in water, then he shall be clean.
