Is there a relationship between hair loss and family history?

I always feel this, but I've heard that heredity is really significant.

My father hasn't started losing his hair yet, but my grandfather did.

Is there a connection between hair loss and family history?

My hair loss isn't severe yet, but I think I'm seeing some symptoms, so I'm curious.

I'm wondering if I should prepare in advance.

I would like to know what is the best way to manage this on a daily basis.

Also, can hair loss occur at a young age?
