This man had two sessions of grafts, 7000 and 5000. Most of the grafts clearly did not take. Assuming that all follicular units are excised in the donor area, the total donor supply equals 25% of the total hair supply. The average man has 50,000 follicular units (grafts) on his head, of which 12,500 reflect the donor area (12,5o0 is 25% of the total follicular units). This means that if the surgeons did only FUE, nothing would be left in the donor area (maybe 500 or so). In such a surgery, the patient will likely become either bald in the donor area or heavily overharvested in the donor area if partial follicular units are excised.
There is a misconception that many patients and surgeons must replace the recipient area density. Nothing could be further from the truth. First, look at the above numbers. Assuming that a patient has a Class 7 balding pattern, he is only left with his donor area remaining, which contains 12,500 grafts. A Class 7 balding area contains 37,500 Follicular Units (grafts). If all of the grafts in the donor area (12,500) were moved to the entire bald scalp and 100% of the grafts grew, then the patient would have achieved only 33% of their original recipient area density and become bald in the donor area. This is simply mathematics. So, transplanting into the recipient area should not blindly remove as many grafts as possible and move them into the recipient area. A surgeon, with proper knowledge of both the original donor density and hair mass of the patient’s donor area, can make appropriate artistic and mathematical calculations to obtain good results with less than the original recipient area density achieved. I have done this thousands of times on very bald men, even those with a Class 6 or 7 pattern of balding, and never removed 12,5000 grafts over the 33 years I have donr hair restoration surgery.
FYI: 50% of recipient area density in a man with black hair and white skin is as good as 100% recipient area density. This was demonstrated by Dr. Manny Marrit some years ago when he plucked out 50% of the hairs on one side of the head of a man with medium-weight hair, which was black, and his skin was white. No one could tell the plucked side from the on-pucked side.
This man needs an expert hair transplant surgeon to figure out what was done and how to give him a satisfactory appearance, if possible. This is something I have done a thousand times or more.
