Adam Clarke on 1 Corinthians 11:15

But if a woman have long hair - The Author of their being has given a larger proportion of hair to the head of women than to that of men; and to them it is an especial ornament, and may in various cases serve as a veil.

It is a certain fact that a man's long hair renders him contemptible, and a woman's long hair renders her more amiable. Nature and the apostle speak the same language; we may account for it as we please.
