Yes. I have had folliculitis a few times. Once on my scalp, once on my neck, and a couple of other places. It's horrible. I'm female but it's probably worse for men since they have to shave their faces and they may be more at risk of them, I don't know.
I use basic self care at home but if it looks like it needs it, off I go to the GP to get antibiotics. I don't think it's caused by lack of hygiene or even necessarily high blood glucose levels. Just one of those things.
