you need a power adapter - the sockets there are different, too. The adapter will have resistors built in to convert the voltage, and will go in the spanish socket but have an american outlet.

You need a big heavy expensive transformer (step down) with a rating equal to that of the hair drier. see second reference. $60, weighs 25 pounds. Better is to spend the few bucks for a dual-voltage drier. Cheaper, and you don't have to lug the transformer around. I have one Iv'e used on trips for a lot of years. see first reference. About $10-20 .
