Beard transplant and wispy hair. Any suggestions?

I got a beard transplant with 2k grafts 8 weeks ago. Luckily, I did not have all hair fall out. About 2 weeks ago I shaved all of it off. Issue is that the hair that grew back is quite fine. Question 1.Is the hair that grew back actual of how these shafts will remain or do you think these shafts are just preliminary and that over months will grow thicker? If you look at the picture from donor area the hair there is slightly thicker. 2. Do the follicles grow more then one hair shaft?
