From what I understand of Orthodoxy in Russia, it's generally only clergy that grow beards and maintain long hair, and seminarians specifically maintain short hair and are clean shaven, lest they come across as presumptuous.
As far as other culturally Orthodox lands are concerned...I have no idea.
Theology has nothing to do with Hair or any body parts, this issue is only valid as a cultural and social topic.
I have long hair, and when getting ready to take my mother to Greece in 1999, I asked her if I should cut it short, so I would "fit in" with our cousins there whom we had never met. My mother shocked me when she said no, leave it long, just get it styled as I always did.
When we had met some of our relatives after looking awhile, they wanted to take us to see the other first cousins, so we went to my moms first cousin on her mothers side, Christo, and his wife , they have a son who is Bishop Dorotheos , head of Syros area Islands whom they are very proud of, but as we sat with them Christo did not say much and my Mom had the feeling he did not like us, when we were leaving though, he started to cry uncontrollably, later my Mom told me she did not understand how he acted.
The next day our Cousin Elias who had taken us the night before to Christos house said we were going there again right away, my mom said to him she did not think he liked us , as he said little and seemed to be bothered by us. Elias said we must go, that we did not understand the problem was not us but something else entirely.
So we went back and had a very pleasant evening with Christo and his lovely wife Katarina that night.
The point of this story is that in addition to their son who is the Bishop of the Islands, They have another estranged son named Niko, who had been living in Athens since he and his father had an argument about his HAIR length.
When his dad Christo saw me with long hair the first night, he was struck that it was the hand of God, telling him he was foolish to ignore his son over his hair. The next day, unknown to us, he had talked to his son for the first time in years , and asked him to come home.
His son Niko came home later that year and lived at home again, His dad lived only another two years.
So it's true, the Lord works in mysterious ways.
