I need a haircut as well, last I went when they first opened them back up here, you need to wear a mask all times and just hold it over your face while they clip along your side so it doesn't fall off, that and no waiting room, appointment only and wait in your car.
As for the hair tips, I can't help you there. I've got no style and no real opinion on what looks best. I would say don't over think it though, be natural and be yourself, that's going to be way more charming than your hair style.
