Will the hair in the FUE donor area grow back again?

Thank you for your question and photos.Yes ıt will grow back.
the number of grafts a patient will need depends on the thickness of their hair and the extent of their hair loss, which can be determined by the Norwood Scale below.
During a hair transplant, grafts are usually removed from the ‘donor area’ located on the back of the scalp and relocated to a balding area. The back of the scalp makes a good extraction area due to the high volume of hair follicles that congregate within that region that are not affected by the balding process. Specialist surgeons will remove a small amount of tissue that can grow hair and relocate it to the desired area of the head without damaging them.

The donor area follicles are removed and transplanted to other areas of the scalp. Although follicles continue to generate new hairs as hair falls out, follicles do not regenerate. This is why it is crucial not to over-harvest the follices. I would think as the hair in the photo grows, you will not have visible bald spots in the donor area.

When we take out graft from donor area, we take out whole hair follicle and hair growth will suffer.This is expertise of the Hair Transplant surgeon how to take grafts so that there is minimum loss to donor area.
