Some men may feel uncomfortable growing a beard (I'm told it itches), but feel free for this month to grow out your facial hair. Don't do it to catch a lovely lady- do it for yourself. Do it because it's No shave November.
Men have come a long way in as far as hairstyles are concerned at least with what is acceptable in the general sense. Today, you will not be surprised to see a guy sporting a crew cut or a guy who has hair flowing up to the shoulders.
