1 Corinthians 11:13-15

So then you can decide for yourselves—is it proper for a woman to pray to God with her hair unbound? Doesn’t our long-established cultural tradition teach us that if a man has long hair that is ornamentally arranged it invites disgrace, but if a woman has long hair that is ornamentally arranged it is her glory? This is because long hair is the endowment that God has given her as a head covering.
