For what it is worth: I have long believed that “Doth not nature itself teach you” means what naturally takes place in the absence of unnatural or artificial interference.

If you observe nature in relation to hair of a man, versus hair of a woman, what might you notice? That a man will go bald at a rate much higher than a woman will. And as a result of this being normal, he will not be ashamed of his baldness. He may in fact even choose to shave his head and be bald. It is in fact quite common for men to do so.

Women? Not so much. They are typically ashamed of baldness. Some may do it but it is not common.

This is in my opinion what Paul means by nature itself teaching us. It is unnatural for a woman to be bald. It is not unnatural for a man to be bald.

For what it’s worth, I’ve never had anyone agree with me on this point that I can recall. So there’s that.
