I have to also agree with @ingrobny and @AGENT_58. I’m sure it sucks to have hair issues at such a young age but you may find it very liberating and a huge stress reducer by just ridding yourself of it completely.
My experience: I’ve got a few decades on you and haven’t had any hair issues but a couple years ago went thru kind of a stressful rough patch and just shaved it off to simplify my life in the seemingly smallest of ways. So glad I did it. Personally, I think I look better with my hair grown out but yet my social life (dating) hasn’t missed a beat and it still feels amazing not to have to worry about my hair. I will never grow it out again.
And yeah, if you can do a little scruff with the facial hair, I also think that’s a good look.
I know it’s a different situation with you but if the constant attention you need to put to your hair causes you stress, anxiety or feelings of being self-conscious, you may be happier saying “screw it” and go the way of 47. But do what’s best for you.
Best of luck either way.
