As someone who has it, it's not that simple. Imagine a quarter sized bald spot somewhere random on your head. Maybe it goes away in a month. The next time imagine 3 dime sized spots on the edge of your hair line. It's one of those "going full bald " seems like overkill when you are so close to "normal" in most cases. Also, I can't speak for his experience but that's a lot harder when it's an eyebrow, which is my current situation... Maybe it will come back, maybe it won't.
