Should Single Women Cover Their Heads?

In this episode Dr. Betters answers the question, " Dr. Betters, I seek to obey all of my Saviour's commands and expectations. Paul writes about how women should cover their heads while praying as a sign of being covered by their husbands, Paul states the hierarchy: God is over men, husbands are over their wives (and children). But what about single women, who obviously don't have husbands over them? I've never been married, so do I not cover my head with a veil or scarf?"
