Hair dryer recs plus where do I sell an expensive one I bought that doesn’t work for me at all

Hi all, I just moved to Japan and am already having hair related problems. :(( I bought a Refa hair dryer hoping it would be worth the hype but unfortunately it’s not strong enough to straighten my 3a hair. The one I used in Europe was 2300w, so I’m trying to find one that is at least 2000w.

Apparently, Refa does not accept returns so I’m pretty stressed I just spent 58,000 yen on something that doesn’t work at all. Is there any second-hand store where I can bring it in and sell it?
