Since the image of a male metal fan usually includes long hair, I want to know how accurate that image is in the current era. Hopefully the answers cover everything, but to elaborate:
If you used to have long hair, but don't anymore by your own choice (didn't like it, too much effort, etc), use answer 2.
If you would like to have long hair, but are required to keep it short due to a work/school dress code, then take answer 3.
If you're bald, pick the answer that would apply if you still had hair.
If you're female, it's not unusual to have long hair. Don't vote. (I genuinely want to know the answer to this, sorry)
I'm not sure what counts exactly as 'long', so use you're own judgement. Although I'd say hair that reaches your shoulders counts as long.
My hair is long, usually a bit past the shoulder blades and nipples.
