Dandruff is skin that flakes and falls off your scalp. If you shave your hair off, the skin on your scalp will still probably flake and fall off. On the other hand, with no hair for the dandruff to get stuck in it will probably fall away unnoticed.
If you take proper care of the scalp after shaving then the dandruff will go away. Dandruffs have nothing to do with your hair, which means that you can still get rid of the dandruff without shaving off the hair.
