Theory On Why Rob Got His Haircut

Ok so Rob Hates when people scream at him and his fan base is incredibly HUGE. During interviews, and on TV shows he pulls his hair. Either that was a BAD habit or a sign of stress. Maybe just maybe he sometimes pulled his hair Out? I dont know it is just a theory. A theorpist told me that it could be stress. Now we don't know why he did it exactly but this is a resonable heory isn't it? Now he cant pull his loved locks. Then. Do you see how hard he's pulling it. Now. NO hair pulling.
