I imagine the "hair" as essentially a helmet of cartilage intended as a soft cushiony second layer of protection for the brain where the psychic power is focused. This is why it's shaped so firmly but still appears slightly malleable.
I imagine the skin as a typical mammalian skin but smoother, though that's not really based off much and there's certainly an argument against it what with the Amorphous egg group.
