New Testament writer had long hair

[Aquila]

I think there's a leap in logic in some posts here. Paul explained to the Corinthians that long hair was a shame on a man but a woman's glory. And that if a woman uncover her head (actually head covering but we apply it to hair) it dishonors her head (her husband).

Where does it say that long hair on a man or short hair on a woman is "sin"? Sin is the breaking of God's commandments. Sin is a heaven or hell issue. Paul is talking about propriety, modesty,proper appearance, and conduct in the church. A shame isn't the same thing as a sin.
