Many people wonder if Al Pacino had a hair transplant or wears a hairpiece. If it's a wig, his hairline looks unnaturally straight and the fullness is quite alarming. But, if it's a hair transplant then I would have a theory as to why... If you notice, the side of his head is balding around the temporal peaks, but the hairline is still intact. It's possible that he had hair plugs or a transplant a long time ago and only had the temporal peaks filled. Then 5 or 10+ years later he started balding behind the temporal peaks. Do you think Al Pacino wears a hairpiece or had a hair transplant?
