Will my hair in the donor site grow back after the transplant?

No, it will not grow back, but as the follicles are harvested from the scalp of the nape, which has the densest concentration of hair, there will be a slight thinning and the effect should be hardly noticeable. The remaining hair around the donor site will be more than enough to conceal the thinning.

The surgeon will extract hair follicles within a certain distance from each other, so there should be no bald patches. The hair roots in the donor site are much denser than other areas. People will not visually notice a difference.

Only if the hair is pulled apart and examined closely, a careful eye can spot the difference.
