I had 3000 FUE grafts and I am worried about my donor area (photo)

When your original donor density is lower than average, 3000 grafts can be too many grafts harvested through FUE and this causes donor site depletion such that the donor area has a problem with a see-through look. The doctor should have measured your donor density before pushing large numbers of FUE grafts. For some people with very low donor densities, 2000 grafts could cause donor site depletion. It seems that in this situation, the surgeon could not get the entire 3000 grafts from the permanent zone, so the surgeon moved outside the permanent zone into the neck (which is not permanent hair) and possibly also above the permanent zone into another area that may sooner or later may bald.  The only treatment for this is scalp micropigmentation, something we do all of the time. https://scalpmicropigmentation.com/  This technique can make your donor area LOOK normal but it will not put more hair there
