At 28 that looks very solid. You'll likely follow the same pattern as your father but I'd imagine at a fairly slow pace. I would just keep an eye on it with photos every few months and get onto finasteride if you notice any damage
Of course it does. But Im really enjoying the buzz cut, I will also try to grow my beard more and I think I could pull of a quite good look. So even if I would be lucky enough to keep my hair, I think I still would keep it buzzed with a nice beard on it.
