My cat’s hair has grown back in after being shaved….but he still bites…what should I do?

My cat’s hair has grown back in after being shaved….but he still bites…what should I do? He does it on his neck, starting at his ears then moves down across his shoulders all the way down to the base of his tail. It just about looks like he is trying not too scratch himself anywhere else but that part of his body..his fur is growing back where it was shaved off so its not really an issue yet or why they are doing this behavior but once its time for him be groomed again it worries me because if there are no problems with shaving them off how would you treat whatever caused their problem?? Please help me out here guys!!
