Transplanting 5000 grafts in one session is surgically not advisable. Subjecting a patient’s scalp to too much extraction and implantation will put too much stress and strain on the scalp; this can lead to too much bleeding, discomfort and pain after surgery, slow recovery and low graft survival.
Secondly, we also have to look at donor density and availability. There is a percentage limit on how many grafts can be extracted in a specific area in order to leave sufficient hair coverage that will be undetectable after the surgery. Extracting 5000 grafts at once might leave the area looking open and sparse; which will not look natural.
Thirdly, Its necessary to save some donor hair for future use if need arises. This will help cater for cases like future hair loss and low graft survival in a previous surgery. 5000 grafts extracted will limit your donor hair for any other surgery.
Lastly, extremely long sessions might have low quality results. The level of concentration for the surgery staff is best within 9 hours; beyond that, the quality of service, precision and accuracy might be affected resulting in poor results in some places.
Our recommendation is to stick to normal sessions of about 2500-3500 grafts. Then you can observe the results, after one year, you can take another surgery to improve the results of the first surgery.
