鬀髮（上體討反說文云鬚髮也從髟弟聲大曰髠小兒曰鬀盡及身毛曰鬄音釋髟音必遙反髠音兀）。

Shaving hair (鬀髮: the first character has the fanqie 體討. The Shuowen says: "Beard and hair." It takes 髟 as radical with 弟 for phonetic value. For adults it is called 髠, for young children it is called 鬀, and removing all body hair completely is called 鬄, pronounced 釋. 髟 has the fanqie 必遙; 髠 is pronounced 兀).
