Man oh man you get them all don't you. I've had lupus for 26 years and I've never heard of lupus causing ingrown and infected hairs on our heads. This is a new question, I have one for you. I know that you use a cpap machine.
I know with my machine that I develop ingrown hairs along where the headgear sits at the base of my neck. Or they can even come up as whitehead on my check where the straps sits.
It's possible that your headgear is whats causing them. If you truly think they're related to your lupus I'd recommend you see a dermatologist. Sorry,I don't feel like I was a lot of help. Hang in there joy and I sure hope they heal up.
