For men, short hairstyles are nothing unusual since the majority of men in this planet sport this style. These hairstyles are popular for many reasons, such as religious principles (most Christian denominations require a man to have short hair so that his head is not covered when he prays) and one's profession (e.g. athlete, military personnel, or businessman).
No matter what hairstyle you choose, it is important for the hairstyle to not only fit your facial shape and skin tone, but it must fit your personality too. In spite of the fact that hair grows out, you have to be comfortable with the style from the beginning. Most of us do not have the luxury of calling our employer and saying "I'm not coming to work for the next few weeks because I don't like my new haircut." Probably more than any other hairstyle, short hair takes courage because if you don't like it, other than a wig, there is nothing you can do about it. You must be patient and wait for Mother Nature to change the length.
