Philly,
If you have spoken with anyone peripherally involved in the entertainment industry who has seen Brad in person, they will tell you that he has some of the prettiest, thickest hair you will ever see on a middle aged man. He literally has hair every bit as good as most women, even better.
Alot of men see their beards grey before their hair does. Usually the sideburns grey first. Same way with Pitt.
Pitt genetically has hair about like Robert Redford. A dark blonde that just seemingly will be with him until it turns white, which for both of them will likely be in their seventies.
Philly,
some men just dont have male pattern baldness. I met an italian man once who was in his eighties with a Norwood one hairline and good thickness despite the fact that every hair on his head was snow white. Brad Pitt is one of these men. His hair is very thick. In the movie "The Devils Own", made back in 95', it looked the same way. The same, because it hasn't thinned at all. Its called genetics son, and Brad Pitt has good hair genes. I think you are a little jealous of him personally. Hell, he is f*****g Angelina Jolie, is a multimilloinaire, is healthy, and used to f*** Jennifer Anniston. There is good reason to be jealous. Oh and yeah, he has beautiful hair and a handsome face......that too
