a few months ago I developed a few sores in my hairline at each temple. A hair was in the middle of each sore and when pulled would uncoil from beneath the skin. The hair that was beneath the skin was bent at severe angles. Over time the area spread from each temple to the back of my head.

If I notice a hair at an odd angle early enough I can pull it free and avoid it turning into a sore.

I have been treated with alcortin, evoclin, griseofulvin, minocycline and antibacterial shampoos. None of these has had any effect on my condition.

Any advice on what can be causing this?
