Ive never been able to grow anything, but I have whiskers all over my face. About three months ago, I started seeing large amounts of hair coming in finally. Over the past two weeks, it's suddenly all started disappearing as if the terminal hairs are becoming thin and falling out. I'm only 20. I don't have chest hair yet. But I don't have hair loss problems on my head or legs or down below. Any idea what could be causing this? Should I see a doctor? Anyone experience anything similar?
