Joey Fatone just said bye, bye, bye to balding -- the ex *NSYNC singer has a brand new 'do, and it's totally real ... courtesy of Bosley hair restoration.
Joey says he started going bald during *NSYNC's heyday, but wore hats to hide it ... adding, "It was pretty intimidating. That's life, but the beautiful thing is that now you can do something about it."
If Fatone sounds like a pitchman ... it's because he is now. Joey just shot a new commercial for Bosley.
If only something could have been done about Justin Timberlake's cornrows.
