I have had 5500 FUE grafts, what is wrong with my hair now

You had 5500 FUE grafts which is almost certainly too many grafts for your donor supply. You now have donor area depletion which is essentially balding of the donor area because too many grafts were removed from the donor area.  This area will not recover. The only treatment for this that could help you hide the balding in these areas is scalp micropigmentation which, although is not hair, will hide the balding if you keep your donor hair very short. I believe that too many doctors are being pushed by many patients to perform more and more FUE transplants to fill in the balding area. This is the result if pushing the technology. Doctors should assess the donor density and know just how many grafts the donor area will support before doing the surgery.
