I've had some grey hair since 17 - visibly noticeable by... 19 or 20. My dad was basically gray/white hair by early 40s, and I inherited that trait. It was certainly noticeable by my mid 20s, and probably both helped and hurt along the way in various business/job/work contexts. Never could grow a beard, so 'graybeard' has never been a literal issue for me. :) In my mid 30s, I could, at a distance, pass for late 40s or 50. As I've moved towards that milestone, I don't think there's been much of a change. That's not just me thinking that - I get told that now and then.
