My reasoning being that electrons rub off the plastic comb, leaving it positively charged. Electrons from the de-ioniser should restore it to neutrally charged.
Not a perfect answer by any means. You need to know the type of plastic the comb is made of and some plastics take on a negative electrostatic charge when rubbed on wool.
