It's heredity and lifestyle/diet choices.But there are lots of guys who don't suffer from male pattern baldness. My dad has always had a full head of hair and he's 62 lol.
I dated a guy who was 38/39 who had a full hairline with very little gray. His brother who was I think 40/41 had a full hairline, but gray hair, but lived a very unhealthy lifestyle (drinking, smoking, partying). Then after him I dated a guy who was 34 who was suffering from male pattern baldness (receding hairline), but he worked in law enforcement and was in the army reserves, smoked cigars, drank alcohol with an unhealthy greasy food diet.
