Can grafts be added under my jaw line to improve the look of my beard transplant?

Yes for all of your questions. Yes you can have a transplant into the jawline. Yes you can extract from the sides of your head. The amount of grafts will depend on the surrounding density which should be assessed by the hair restoration surgeon of you choice. If the last clinic cannot do it, find one that has experience with it.

Beard transplants can be placed under the jaw line but you and your surgeon must woprk it out as I am in Caifornia and can't tell you what your surgeon will do
