Donor Site Safe Zone
Professor Unger studied 328 men aged 65 years or older and determined the safe donor area (safe zone).
When you are 80 years old, 80% of the chance that your safe zone at occipital area is only 7 to 8 cm wide, at lateral and posterior area only 5 cm wide.
If grafts harvested are not in the “safe zone” then hair at that area are not permanent hair. When the surrounding hair loss or even get thinner, thousand of scars will appear and extremely difficult to cover up.
