facial hair can be good or bad depending on its length and your situation.
clean shaven - you look sharp, groomed, hygienic. it could also make you look like a safe guy, not much edge without the facial hair.
5'oclock - depends. you look like you dont care about your grooming habits, which can be a good or bad thing depending on the person viewing you. it gives you some edge. can make you look mysterious and possibly have something to hide/cant be trusted....again can be good or bad.
good length and groomed facial hair - provides the benefit of the above 2. you look groomed with good hygiene and you have a good edge. however on interviews or in the workplace, employers may disapprove of this because facial hair sometimes classify higher status/maturity subconsciously. no boss wants to feel that way.
