Ben Affleck hair transplant?

I always heard he wore a piece but it looks like he still has most of his hair except for a pronounced bald spot on the top. Any ideas on what he's’ done to keep the front. He till looks like he has a lot of hair.

If he did have a hair transplant it must have been FUE . His hair looks very good to me, and I don't think he had anything done. He’s a normal 36 year old with a little MPB.

Its common knowlegde he wears a piece.
