How long does it take to grow a beard after hair loss

I got hair loss after having scarlett fever in September 2013, so I had to regrow it.
How long does it take to grow a beard? How long does it take for a damaged beard to recover? And does it recover?

I'm writing and photographing it, and you can follow the process on this blog  here:

These are som pictures how it looks right now. I still lose some of my beard. As you can see I've got more beard under my chin, and that's because it was the first place where I lost my beard, so it had grown out again.
On other places my beard still grows sparsely, but its on it's way back.
