Leviticus 13:30-40

30 then the cohen is to examine the sore; if he sees that it appears to be deeper than the skin around it, with yellow, thin hair in it, then the cohen is to declare him unclean; it is a crusted area, a tzara'at of the head or beard.
31 If the cohen examines the diseased crusted area and sees that it appears not to be deeper than the skin around it, and without any black hair in it, then the cohen is to isolate for seven days the person with the diseased crusted area.
32 On the seventh day the cohen is to examine the sore, and if he sees that the crusted area hasn't spread, that it has no yellow hair in it, and that the crusted area is not deeper than the skin around it;
33 then the person is to be shaved, except for the crusted area itself, and the cohen is to isolate him for seven more days.
34 On the seventh day the cohen is to examine the crusted area; and if he sees that the crusted area has not spread on the skin and does not appear to be deeper than the skin around it, then the cohen is to declare him clean; he is to wash his clothes and be clean.
35 But if the crusted area spreads after his purification,
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.
