Beards are usually grown on men who want to appear as mountain men. Some women don’t like it because it scratches their face when they get too close. However, beards may make a young-looking man look older if that is the look they are going for.
Some men have young faces and they want people to take them more seriously, so they will grow a beard. Young men may want to grow a beard right away when they can start growing facial hair because they want to show that they can grow facial hair. When men get older, growing a beard may cover up any flaws they have in their skin. Also, men get tired of shaving and nicking themselves, so they may give up and grow a beard.
