Hamster Comb

I want to find a hamster comb (or brush) for Harry ,he keeps messing his hair & it's driving me nuts! Harry have this nasty habit of exercising @ 2AM & I'm losing sleep, imagine hearing that creaking sound of exercise wheel in the middle of the night (and eventually my neighbors would complain about that teeny weeny creaky sound in unGodly hour.well sue me hmp.)
