The leprous person must shave off all his hair prior to purification

"It will be on the seventh day that he shall shave off all his hair: he shall shave his head and his beard and his eyebrows, even all his hair. He shall then wash his clothes and bathe his body in water and be clean.

Hebrew

ט וְהָיָה בַיּוֹם הַשְּׁבִיעִי יְגַלַּח אֶת-כָּל-שְׂעָרוֹ, אֶת-רֹאשׁוֹ וְאֶת-זְקָנוֹ וְאֵת גַּבֹּת עֵינָיו, וְאֶת-כָּל-שְׂעָרוֹ, יְגַלֵּחַ; וְכִבֶּס אֶת-בְּגָדָיו, וְרָחַץ אֶת-בְּשָׂרוֹ בַּמַּיִם--וְטָהֵר.
