Understanding donor over-harvesting: clinical definition, causes, what patients can do and how Hairmedico prevents it.

Clinical definition

Over-harvesting is defined not by a specific number but by biological tolerance. Poorly distributed extractions concentrated in one area cause over-harvesting even with moderate graft counts. The threshold varies by patient hair type and donor density.

Why clinics cause it

  • Commercial pressure to maximise graft counts
  • No calculation of lifetime donor capacity
  • Concentrating extractions rather than distributing evenly
  • Technician-performed extraction without surgeon oversight

What affected patients can do

Mild-moderate: PRP therapy improves density of remaining follicles. Scalp micropigmentation (SMP) cosmetically disguises the donor zone. For severe cases, body hair transplant (beard or chest follicles) provides limited additional donor supply. Reversal of removed follicles is not possible with current technology.
