I agree with you guys that the inheritance of male pattern baldness can be very unpredictable. It often really is "pot luck" who gets the good genes or the bad genes (Prince Harry and William, for instance). However, the OP of this thread said that nobody at all is bald in his family. Of course, it isn't clear what degree of hair loss he considers to constitute "bald" in this instance. If it is the case that all the known males in his family background had thick NW1s their entire life, then I think it is safe to say that his chances of developing male pattern baldness (especially prematurely) are very small. It looks from his photos like he may have some temple recession, but that could just be the development of a mature hairline. Definitely he should keep an eye on it though, and definitely see a dermatologist to get a professional opinion. If the crown starts thinning in addition to the hairline "maturing", that would most certainly be classic male pattern baldness rather than a mature hairline. And if that's the case (referring especially to those in their teens or early 20s), then yes, it's life completely and utterly over I'm afraid.
