Question:
What age do guys grow a full beard?
Answers:
Well, I'm nearly 21, and still can't grow a beard ( or mustache). Looking at the males in your immediate family may help you get an idea, but not always. My dad has been able to grow a full beard since he was 15. Both my grandfathers had them by the time they were 20. It is really one of those things you have to wait for to find out.
