Brad Pitt doesn’t wear a hair system. His hair is so amazingly perfect and thick even pushing 60 that it makes balding guys think he’s wearing a piece. He’s been making movies since his 20s and if he was losing his hair or something was going on with his hair we would see it in movies and photos. It seems like every male actor that has a great head of hair has been accused of wearing a piece. It’s hard for some of us to accept they were blessed with great heads of hair. I’ve seen women running their fingers through Brad Pitt’s hair in movies and the wind blowing his hair. That’s definitely his hair. He was in a movie in 2015 where it looked as if he was wearing a wig due to the hairstyle. He was asked about it and said that was his own hair. As for Matthew McConaughey, he’s either wearing a piece or has had transplants. I’ve seen photos of him thinning so he’s definitely had something done.
