Receding hairlines that dont recede

In yesterday 's snl, Walton goggins argued that he had the same famous hairline since he was 7. https://youtu.be/2layt7-x2qc?feature=shared

While I think he might be joking here. My dad had a nw2 at 25 or so and it only reached nw3 in 2025 when he's nearing 60. Does anyone know how common this is?

For the record I'm 24 and so far balding with my dad's pattern. I'm on fin and it's holding but my dad argues I don't need it.
