Keeping hair straight in humidity

Hi! I have naturally super curly hair, but I have bangs so I always flat iron it. I like to wear masks to cover my nose due to insecurity, but even within a few minutes my breath makes it revert back, even with hairspray.. I’ve tried anti-humidity spray but it didn’t work. What can I do?

Please don’t say anything about wearing my hair curly or heat damage or “accepting my nose”, I’m just not interested in discussing it. I don’t wear masks currently because of this problem.
