Harry Potter Golden Age

From personal experience I find that men with that very black hair do go grey awfully early (and women, for that matter). I was at Uni with a guy and his sister, both in their 20s, who had a lot of grey in their black hair, then in my 20s I lived with a guy with black hair and he was starting to go grey before he hit 30.

Mr Birds is also very dark haired and started to go grey in his 20s, so I suppose Harry having a few grey hairs at 34 is not really much to talk about.

I think Draco's receding hairline was a caddish low blow from JKR, though. She never liked him! Not that there's anything wrong with losing your hair, (looks fondly at Mr Birds) but we all know Draco would bloody hate it!)
