Leviticus 13:36-46

36 then the cohen is to examine him; and if he sees that the crusted area has spread on the skin, the cohen is not to look for yellow hair; he is unclean.
37 But if the crusted area's appearance doesn't change, and black hair grows up in it, then the crusted area is healed; he is clean; and the cohen is to declare him clean.
38 "If a man or woman has bright spots on his skin, bright white spots;
39 then the cohen is to examine them. If he sees that the bright spots on the skin are dull white, it is only a rash that has broken out on the skin; he is clean.
40 "If a man's hair has fallen from his scalp, he is bald; but he is clean.
41 If his hair has fallen off the front part of his head, he is forehead-bald; but he is clean.
42 But if on the bald scalp or forehead there is a reddish-white sore, it is tzara'at breaking out on his bald scalp or forehead.
43 Then the cohen is to examine him; if he sees that there is a reddish-white swelling on his bald scalp or forehead, appearing like tzara'at on the rest of the body,
44 he is a person with tzara'at; he is unclean; the cohen must declare him unclean; the sore is on his head.
45 "Everyone who has tzara'at sores is to wear torn clothes and unbound hair, cover his upper lip and cry, 'Unclean! Unclean!'
46 As long as he has sores, he will be unclean; since he is unclean, he must live in isolation; he must live outside the camp.
