Source: Nav
Leviticus 13:29–33
If a man or woman has an infection on the head or chin, / the priest shall examine the infection, and if it appears to be deeper than the skin and the hair in it is yellow and thin, the priest must pronounce him unclean; it is a scaly outbreak, an infectious disease of the head or chin. / But if the priest examines the scaly infection and it does not appear to be deeper than the skin, and there is no black hair in it, the priest shall isolate the infected person for seven days.
Leviticus 14:9
On the seventh day he must shave off all his hair—his head, his beard, his eyebrows, and the rest of his hair. He must wash his clothes and bathe himself with water, and he will be clean.
