Makhya,
While I cannot see your crown area, generally speaking, one requires 1000 grafts per level on the NW scale. You seem to be about NW5 and could head to 6 or 7 depending on your genetic pre-disposition.
So to recreate the illusion of density, generally valued at 45 FU/cm2, at this point in time, you will need approximately 5000 grafts( and since the mean normal graft size is 2.2 hair per graft) that is approximately 11,000 hair.
As thanatopsis_awry said, the first priority is re-establishing the hairline as without a hair line the eyes are no longer the face's main focus-point and the ocular attention becomes dispersed, oscillating between the face and the alopecia region.
Also as thanatopsis_awry said, you will not get total coverage in one session, but will require multiple sessions throughout your lifetime in order to maintain the illusion of density.
Only a few surgeons practise "megasession" where they transplant, more than the average 3000 grafts. You will need to investigate if you are a suitable candidate for this type of FUT.
Hope this answers some of your concerns, and as always, I am open to criticism from the experts.
