Help!!! I have been dealing with a bizarre scalp issue. I was first diagnosed with seborria dermatitis (sp.) in December. I have very thick hair. I was prescribed a shampoo "capex" that was a cortisone. After 6 months I developed what I believe is foliculitis....I think I was misdiagnosed all along. I see dirt, greenish hair, brown specks, etc. etc....could it be a fungus? I do have some breakage but I could have caused this by pulling on it. I felt like I was infested but never once saw a bug or any living thing....i wash my hair way to often....i have beeat least twice a day.....i m obsessed.....i have been to the dermatologist at least five times.......they never biopsied or have done anything but prescribe medicine.....
