My boyfriend has had a problem with his hair follicle for years now and no one can seem to figure out what it is. He says he has pain in his head and once he pulls a certain hair out he gets relief. The hair he pulls out is covered in a gel like coating at the root, and it has been tested for fungus, etc..and those tests were negative. Any suggestions on next steps, it is not trich, and not folliculitus? Thanks in advance for any help.
