Well, one answer anyway. The life span of a hair dryer? Less than one day.
I brought the new one home from the store. I washed my hair yesterday morning. Plugged the dryer in. There was a whirring sound, a puff of smoke and then nothing. I didn't even get to warm my hair up. There I am with soaking wet hair and I have to leave for work in 15 minutes.
So I took it back to the store on my lunch break. The lady at the exchange desk took one look at my hair and refunded my money. I won't even post a pic. Dreadful.
Hopefully this new one is up to the task.
Have you ever been worried about washing your hair?
