How Do I Know if My Donor Area is Depleted?

How can someone figure if their donor region has been depleted? Is it evident by the appearance and volume of the donor region; would someone who has a depleted donor region have somewhat of a see through look in that area? I have had two FUHT both around the same size, 1350 grafts each, totaling 2700 grafts. Both of the strips were about six inches long and 5/8 of an inch wide and were remove from the exact same region of my scalp, second strip removed from the previous scar. My doctor says he could easily get another strip totaling 1300 grafts if not more from on top of my now existing scar. I’m a little skeptical of this. Although my donor area still appears just as thick as it ever was, that seems like a lot of grafts from just that small region. I would have totaled 4000 grafts and barely even touched either of the sides of my donor region, having just used the back region. Is this plausible? Side note my donor density is slightly above average

Usually 2700 grafts will not deplete the donor area. You need to have expertise in examining a donor area to make that assessment. If you do not trust your doctor’s opinion, get a second opinion. The depleted donor area usually has a see-through appearance, especially when the hair is lifted up.
