Male Celebs question

[goldbondmafia]

Just something Ive noticed lately when watching movies and tv but how do so many male celebs have such mature hairlines yet still have thick hair. Their receeded hair gives all these guys bigger looking foreheads too (unless im seeing things haha) but im dont understand how they still have all the thickness.. For example;

Bradley Cooper


Mark Wahlberg


Matt Damon



Have these guys done anything with their hair? Im skeptical to believe its all just natural especially when basically every top male actor has a really mature hairline with thick hair. Obviously they get better treatment then us since there rich but what can they be doing that we can't afford?
