I went to see this dermatologist who told me she was the "hair expert." She gave me a prescription for a medication that you rubbed into your scalp. By the way I guess I should mention that first she took a biopsy. She didn't even numb me, just cut out this piece from my scalp. It said I had scarring, alopecia and one other thing that I have forgotten. What they did not tell me was that this medication raises your blood sugar. I live alone so I have no one to check on me to see how I am doing. I was close to being in a coma after several days before I figured out what was doing this. So I stopped and almost immediately started to feel better. Then I saw a different dermatologist. He prescribed a different medication; this time in a pill form. But I refused to take it. I am 90 years old. I take two medications for blood pressure and that's it. If I made it to now without all those meds, then not taking them will not make me sick. I am a healthy 90 year old.
