פירוש על ויקרא 13:40

קרח הוא טהור הוא HE IS BALD, HE IS CLEAN — clean from the uncleanness of נתק (a scall in a hairy spot) (Sifra, Braita d'Rabbi Yishmael 15), for he is not subject to the law about the symptoms of the head or the beard, which are places where hair grows, but to that about the symptoms of a plague on the skin of the flesh — [white hair], healthy flesh or the spreading of the plague.

ואיש כי ימרט ראשו, “or if a man loses the hair on his head;” baldness of women is not mentioned here seeing that her head does not become bald. (Talmud, tractate Nedarim folio 30)

איש, from the fact that the Torah speaks only of איש, “a man,” how do we know that the same law applies to both women and minors? We know this from the superfluous word צרוע in verse 44. We know that this term applies to every category of human being.
