Hair on Fire

I just had an almost disaster here at home. I was using my mother's blow dryer, experimenting with my hair. You see, I never had my hair at a considerable length ever. True, it's still quite short for hairstyling experiments but I'm excited! I have hair that I can blow dry! So there I was just blow drying away, feeling the heat coming from the device. Then I felt that the air coming out was becoming hotter than usual but I didn't mind it. But my scalp was feeling too much of the heat. Then I smelled something. It's not exactly the smell of something burning but it is the smell of something very hot. I looked at the blow dryer and an orange glow was emitting from the inside! I freaked out. I turned the blow dryer off. Unplugged it. Checked if my hair was on fire. Thank goodness it wasn't. Checked if my scalp was feeling a burning sting of any sort, there wasn't any. My hair still looks fine. My scalp feels fine. But I'm guessing the blow dryer isn't fine. I guess it's time to retire my mother's ancient blow dryer, buy a new one and avoid another mishap.
