Donor Site or known as Donor Area is typically located on the back of the head, as this area has a high density of healthy hair follicles that can be transplanted. The hair in the donor area is usually thicker and stronger than the hair in other areas of the head, making it ideal for transplantation. The donor area may also be known as the “safe zone” as it is not usually affected by factors such as genetic hair loss or alopecia. Hair from the donor area can be transplanted to other areas of the head, such as the scalp, eyebrows, or beard.
