In David Brin's novel Kiln People, there is an unclear reference--once--to Ritu having a shaved head, but no explanation as to when or why or how this happened.
Did Beta, her criminal alter ego, make her do it so he/she could more easily control a bunch of giant war-golems?
This is mentioned at the point where Albert Morris has a strange, transcendent experience at the climax of the novel.
"First, look around for Ritu. An earlier version of that wounded-confused soul. You'll detect her soon, filled with self-loathing as she surrenders to an inner craving beyond her self-control, laying her shaved head between the poles of a high-capacity tetragrammatron while autokilns warm up nearby, preparing several dozen giant golems built for war."
