In the 18th century, 17th century, and ancient times, long hair on men was considered aristocratic and classy?

what happened was the rise of representative government. When the nobility was removed from power, often by force, it's trappings were discarded as symbols of all that was wrong and is being righted. Of course when you consider that the short haired servants and soldiers took over they viewed their own styles differently. For a soldier short hair was a sign of cleanliness and attention to detail. Something it still is for soldiers today. As for the servant and lower classes, they emulated the new authorities and what was once a slight became the custom. Consider at the same time that was happening that sign of wealth had come to be a sign of laziness, indolence and parasitism. then a century or two later in american culture long hair lost more face in that it was often used by hippies out of defiance of the social norm or in many cases just laziness ironically affirming what long hair had come to mean so long ago.
