I've been considering buying a hooded dryer because diffusing makes my hair frizzy, and my hair in general is very frizzy because its very fine but I have a lot of it... but I also have flat hair on the top which is why i flip my head over when I diffuse. So...that being said, will a hooded dryer just make my hair all flat on top and give me no volume? Cuz if that's the case I rather keep diffusing and have frizz but have more voluminous hair Here's the one I've been considering buying (or any other good one not exceeding $100):
