5 months and 6 days post op my beard transplant. Will go for another session at 6th month's mark.

Hello doctors. The first two pics attached are of mine with 14 days of growth. I am not satisfied with the result and i am going for another procedure of beard transplant. I am attaching 3 more pics which i took from google. I want to have that fullness. Can you tell me how many grafts will be needed to achieve the same density or at least 70%. Assuming that I will grow my beard for 1 month without trimming. Please guide me. Thank you Note:- my hairs at back of my head are thin not thick.
