English: “Do not let your hair grow wild”: from the special command to Aaron’s sons, the Sages infer that mourners generally are forbidden to cut their hair.

Core Text of Chazal
Core Textרֹאשֵׁיכֶם אַל תִּפְרָעוּ. מִכָּאן דְּאָבֵל אָסוּר בְּתִסְפֹּרֶת, דְּמִקָּאָמַר לְהוּ רַחֲמָנָא לִבְנֵי אַהֲרֹן רֹאשֵׁיכֶם אַל תִּפְרָעוּ, מִכְּלַל דְּכוּלֵּי עָלְמָא אֲסִירֵי.
Type of Learning
Textual inference — the special prohibition imposed on Aaron’s sons is taken to imply the ordinary rule for mourners.
What Is Learned
The prohibition against shaving in mourning is derived from the command to Aharon and his sons not to let their hair grow wild.
