Found this a interesting thing in the article about the nazirite vow in Wikipedia.

--------------------------------
Simeon the Just was opposed to the nazirite vow and ate of the sacrifice offered by a nazirite on only a single occasion. Once a youth with flowing hair came to him and wished to have his head shorn. When asked his motive, the youth replied that he had seen his own face reflected in a spring and it had pleased him so that he feared lest his beauty might become an idol to him. He therefore wished to offer up his hair to God, and Simeon then partook of the sin-offering which he brought.[19]

This teacher lived about 325 BC. The fact that he didn't have a issue with a man having long hair by itself is interesting. If it was a Old Testament norm to oppose long hair in itself you would think he would call the young man out on it. Food for thought.
