Leviticus 13:39-44

³⁹then the priest shall look; and, behold, there being bright spots of a bright whiteness in the skin of their flesh, it is a tetter; it burst forth in the skin of his flesh; he is clean.

⁴⁰And if any one's head should lose the hair, he is only bald, he is clean.

⁴¹And if his head should lose the hair in front, he is forehead bald: he is clean.

⁴²And if there should be in his baldness of head, or his baldness of forehead, a white or fiery plague, it is leprosy in his baldness of head, or baldness of forehead.

⁴³And the priest shall look upon him, and, behold, if the appearance of the plague be white or inflamed in his baldness of head or baldness in front, as the appearance of leprosy in the skin of his flesh,

⁴⁴he is a leprous man: the priest shall surely pronounce him unclean, his plague is in his head.
