Why is Kuririn bald, but gets hair at the end of the series?
Goku asks him this when they first meet (as in, why is he bald when he’s still really young) and he says that it’s to purify his fighting spirit and to keep enemies from being able to grab his hair in battle. Also, Kuririn is kind of a buddhist monk. Later on when he gets interested in #18, he lets his hair grow out so that she’ll like him better.
