Leviticus 13:40-44

40“If a man loses his hair, he is clean, even though he is bald.

41If he loses the hair on the front of his head, he is clean, even though he is bald on the forehead.

42But if there is a pink patch on the bald places in back or in front, a skin disease is developing in those places.

43The priest will examine him. If the sore from the disease in the bald places in back or in front is pink like a skin disease somewhere else on the body,

44the man has come down with an infectious skin disease. He is unclean. The priest must declare him unclean because of the skin disease on his head.
