Or HaChaim on Leviticus 13:29/אור החיים על ויקרא י״ג:כ״ט

1 ואיש או אשה, and a man or a woman, etc. The Torah had to spell out "or a woman," instead of using the collective term אדם for both man and woman because women do not usually grow beards. The reader who sees the word אדם would conclude that the legislation only applies to people who normally grow beards, i.e. men, and I would have assumed that either minors or Gentiles are included in this legislation whereas any plagues on the beard of a woman would not be subject to the legislation introduced here. The Torah therefore wrote איש או אשה, to tell us that if a woman grows hair in a part of her face where a man grows a beard, the legislation applies to her also.
