It comes for most of us men. I'm 35, and the hair line is basically the same hasn't receded or anything. But it is starting to thin a little on the top. Nothing noticable at glance from the front. But if you look at it from the top you can see it's not as dark as the rest of my hair from it not being quite as thick as it once was but overall looks mostly the same. I consider myself fairly lucky to have it only have gotten that far thus far. As I know guys who were forced into shaving completely bald or looking like george costanza in their mid to late 20's. Greys on the other hand, they're definitely starting to storm their way in, but If i'm only slightly losing a bit of hair thickness while approaching my 40's i'd say thats a win in my books. At the end of the day who the fuck am I trying to impress?
