my hairline was like that about the same age...then it kept on creeping and creeping now i just shave the shit off.
wish i had hair but i'm over it for the most part...aside from shaving it your only option is hair transplants, expensive but they work
my bro got them done, close to 10k later he has a dapper set of hair.
if their is ever a genetic cure for baldness i'm on it
