>>82535540the only answer i can think of is he used sharp rocks (or incessant plucking, which will eventually destroy the follicles. don't let your mom do it, on some level she wants you to be a baby forever. it's a sickness) to try to look more like the other gorillas. he was happy when new hair started growing in, until he realized it was in all the wrong places.. so he took care of his face, his chest.. probably gave up on the rest.
though he should have done the same to his eyebrows in that scenario
