Leviticus 14:8-9

8And he that is to be cleansed shall wash his garments, and shave all his hair, and bathe in water, and he shall be clean; and afterwards shall he come into the camp, and shall abide outside his tent seven days.

9And it shall come to pass on the seventh day, that he shall shave all his hair, his head, and his beard, and his eyebrows, even all his hair shall he shave, and he shall wash his garments, and shall bathe his flesh in water, and he is clean.
