Long haired men and business

Karen, I saw that some time ago you wrote an article on long haired styles for businesswomen (I think it was on the long hair international site). Do you have any suggestions on that theme for long haired business men. I wear my below shoulder length hair mostly in a loose ponytail or just free, but sometimes need a more clean look for meetings or just for a change. I am not thinking of anything distinctly feminine but any suggestions which would be considered acceptable for men too would be appreciated.
