After FUE, is it correct the donor area will replenish approximately 25% of the grafts that were harvested from it?

That is incorrect. Once the hair has been extracted from the donor area it generally will not regrow. Sometimes ACELL can be used and with minimal depth of punch and small punches you may see a little graft regrowth however, 25% is very optimistic. If a surgeon is seeing 25% regrowth in the donor area it is likely that the follicles that they attempted to extract were transected and those are the ones that grew back.

Once you harvest the hairs, it does not grow back.  Donor area does not "replenish".  If you are confused about what a doctor may have told you, it may be best to contact your doctor for clarification.

Thank you for your question. The donor area is selected as the donor because of its capability to replenish all of the grafts. NeoGraft's Follicular Unit Extraction method uses an automated system to help ensure accuracy and precision as the least invasive procedure currently available for hair transplants.  I suggest that you move forward and contact your board certified facial plastic surgeon.
