4500 FUE grafts, has see-through donor area

This patient had 4,500 FUE grafts and you can see in the photo the difference between the donor area, which is a bit too high, and the normal hair density on the neck side of the photo. The surgery depleted the donor hair significantly. This is caused by either (1) very fine hair or (2) a low original donor density (something that the doctor can measure in advance).
