Hair dryer fuse too low for spec power?
This is a fairly common thing I've seen consumer products that generate heat like toasters and space heaters for example. I've measured the current draw from various space heaters that are all rated for 1500 watts. The small cheap ones measured around 800w and the largest one was 1300w. I can only speculate why they advertise higher ratings than what it's actually capable of. My guess is for marketing reasons or something to do with UL standards.
