There is a risk of scarring in both the donor and recipient areas. Hence, you should discuss this with your surgeon before proceeding with the surgery.
For instance, the FUSS method usually leaves a long linear scar where the surgeon removed a strip of the scalp. This will be camouflaged as the new hair grows around it or become visible if it widens during healing, the surrounding hair is thin, or the person often sports a short hairstyle.
The FUE method may also leave some scars in the area where the punch tool is used to remove the hair follicles. However, these scars are less visible than the ones from FUSS. In some cases, a person may have raised bumps around the hair transplant. As it grows back, the hair can help to hide the bumps.
