Leviticus 13:35

³³then the skin shall be shaven, but the scurf shall not be shaven; and the priest shall set aside the person having the scurf the second time for seven days.

³⁴And the priest shall see the scurf on the seventh day; and, behold, if the scurf is not spread in the skin after the man’s being shaved, and the appearance of the scurf is not hollow beneath the skin, then the priest shall pronounce him clean; and he shall wash his garments, and be clean.

— Leviticus 13:35 —

³⁶then the priest shall look, and, behold, if the scurf be spread in the skin, the priest shall not examine concerning the yellow hair, for he is unclean.

³⁷But if the scurf remain before him in its place, and a dark hair should have arisen in it, the scurf is healed: he is clean, and the priest shall pronounce him clean.
