Leviticus 13:35-37

New International Version

³⁵ But if the sore does spread in the skin after they are pronounced clean, ³⁶ the priest is to examine them, and if he finds that the sore has spread in the skin, he does not need to look for yellow hair; they are unclean.^{(A) 37} If, however, the sore is unchanged so far as the priest can see, and if black hair has grown in it, the affected person is healed. They are clean, and the priest shall pronounce them clean.
