I am now 1 months after FUE, what is wrong with my donor area?

You have something called ‘donor site depletion’ or you could have shock loss which means that the FUE grafts were taken too close and possibly too many for your donor area to support it. Maybe some of the hairs have been shocked out and may return, but if this continues through the 8th month, then you have a problem, the only solution is Scalpmicropigmentation which can hide the effects of the missing hair very well.
