is this normal?

New question:

I had my crown filled in over a year ago, using classical FUE procedures by a reputable Dr. noted on this site and I am surprised that the density is not very high, and it does not look totally full, and definitely not totally corrected. It was a pretty big job, and a very long strip of donors was extracted - from one side of head to other - practically scalped.

Is it normal to need a 2nd procedure on the crown to get enough density to make it appear as if there was no hair loss at all?

Any ideas what if anything went wrong?

Should I go back to the same Dr?
