Chabad.org — Chumash, English translation + Rashi for Vayikra 13:43
Torah Temimah cites Sifra (Toras Kohanim) for using the ordinary two-week skin-affliction examination framework for bald-area lesions.
Sifra — Vayikra 13, Midrash Sefer
English: The lesion is judged “like the appearance of tzaraas of the skin of the flesh,” using the two-week examination period for ordinary skin lesions.
The baldness lesion is evaluated using the established skin-tzaraas framework.
The lesion on a bald area is evaluated by the same two-week examination framework used for lesions on ordinary skin, rather than the one-week rules for boils and burns.
