Short hair was the dominant, accepted mode for men in the time of Christ. Pick up any good, illustrated history book on the period and you will see the evidence before your eyes. Two good books in this area are A History of the Holy Land, Michael AviYonah, editor, and Daniel to Pad, Gaalyahu Cornfeld, editor. Now notice the busts and statues of various Greeks and Romans of the time of Christ. The men are wearing their hair short on every one of them in a manner similar to that generally accepted today.
