Like the rest of his abilities, it'd be accidental. Maybe a sort of physical reaction, like the way his hair moves. The way it floats unnaturally is a result of his ability, so maybe it reacts towards energy manipulators. Like flowing in the opposite direction of the user in response. So he'd be able to use it as a sort of compass rather than a direct point to point sensory system.

Makes sense, more sensitivity to any sort of manipulation or mustering of energy (blanket term for all magic users) would make sense considering his death.
