Leviticus 13:28-30

New International Version

²⁸ If, however, the spot is unchanged and has not spread in the skin but has faded, it is a swelling from the burn, and the priest shall pronounce them clean; it is only a scar from the burn.^(A)

²⁹ “If a man or woman has a sore on their head^(B) or chin, ³⁰ the priest is to examine the sore, and if it appears to be more than skin deep and the hair in it is yellow and thin, the priest shall pronounce them unclean; it is a defiling skin disease on the head or chin.
