That's not male pattern baldness, thats Vin Diesel. Who's male pattern baldness? Is he famous? What movies has he been in? Any gay fetish movies? You know, those ones where people dress up in animal costu.... er... I've said too much.
He suffers from diffuse thinning. He mentioned it in an interview a few years back that he started shaving once his hair got crap. Make up is used to fill in his stubble effect for some films. If you watch boiler room you can see his horse shoe pattern in some scenes.... they even crack a rogaine joke about his hair.
Guys... he can afford to have thinning hair. Spend 6 days a week in a gym and i will GUARANTEE the ladies will be lining up too. Let's face it, he's not the most atractive looking guy but he does get the ladies. This is odly enough a good topic to talk about because most guys here worry so much about their hair loss that they forgot about their bodies. Hair we may not have 2 much control over but if you want guarenteed results, go to the gym.
