Leviticus 13:42-44

42But if on the baldhead or bald forehead, there is a reddish-white plague, it is tza'arat breaking out in his baldhead or bald forehead.

43Then the kohen is to examine him, and behold, if the rising of the plague is reddish-white on his bald head or bald forehead, like the appearance of tza'arat in the skin of the flesh,

44he is a man with tza'arat He is unclean. The kohen should definitely pronounce him unclean—his plague-mark is on his head.
