as for the long hair vs short hair jesus, long hair was a symbol of holiness and dedication to God we have in scripture:
4 As long as they remain under their Nazirite vow, they must not eat anything that comes from the grapevine, not even the seeds or skins.
5 “‘During the entire period of their Nazirite vow, no razor may be used on their head. They must be holy until the period of their dedication to the Lord is over; they must let their hair grow long.
6 “‘Throughout the period of their dedication to the Lord, the Nazirite must not go near a dead body.
Then you also have Samson who had long hair
16 And when she pressed him hard with her words day after day, and urged him, his soul was vexed to death. 17 And he told her all his heart, and said to her, “A razor has never come upon my head, for I have been a Nazirite to God from my mother’s womb. If my head is shaved, then my strength will leave me, and I shall become weak and be like any other man.”
