Why don’t Christian women cover their head?

But every woman who prays or prophesies with her head uncovered dishonors her head—it is the same as having her head shaved. 6For if a woman does not cover her head, she might as well have her hair cut off; but if it is a disgrace for a woman to have her hair cut off or her head shaved, then she should cover her head.

Corinthians 11:5-6
