Randomly, out of the blue, I've started to get little red bumps around my hairline(slightly into my hair) and just behind and below my ear. They look like a cross between a pimple and a rash. I've tried treating them with acne stuff and also with cortizone cream but nothing works. I wash my hair every other day but nothing helps. Anyone have any idea what could be causing this? Any suggestions of something else I could try?
