GlossaryDonor Area (SDA)

region where hair follicles are harvested for transplantation

The Donor Area, also known as the Donor Site or Donor Zone, refers to the region of the scalp where hair follicles are harvested for transplantation in hair restoration procedures. Typically, this area is located at the back and sides of the head, where hair is genetically resistant to balding, ensuring that the transplanted hair will continue to grow in the recipient area.
