I had very healthy hair before, since stopping Minoxidil will those hairs grow back to their old self?

I started using 5% minoxidil to help grow some patches on my beard. I was using it for about 3 weeks, but experienced a lot of shedding on my head. I had very healthy hair before since stopping will those hairs grow back to their old self? Also I stopped using it almost a week ago, will I continue to shed or should it stop since I am done using minoxidil?
