If MPB Is Genetic, Why Am I Balding Earlier Than My Dad Did?

It is clearly stated that MPB is genetic. So here’s my question…if it’s genetic shouldn’t it follow the age of your relatives when they had hair loss? The only person in my family that had hair loss is my father but he was 32 when it began and everybody else in my family that includes uncles, my two grandfathers especially these 2 had all their hair. So how in the world I’m having early signs at the age of 21? I been through heavy depression and stress in the past 3+ years, could that have triggered MPB out of me so early?

If we inherit it, it will probably be your own hair loss design with respect to timing of occurrence and the degree of hair loss. There is no one-to-one connection year-by-year with your dad.
