Using a hair dryer to melt the ice is definitely not a good idea. You are more likely to break the glass than defrost the window. Drastic temperature changes expand your vehicle's glass rapidly, which can make it crack.
Hot and dry air can hold much more water than cold and wet air, so the fastest way to defrost your windshield is to make the air around it as hot and dry as possible.
