Superstitious nonsense at best... patriarchal and abusive at worst. In summary, women were made for men and must wear a tea-towel "because of the angels."
1Cor 11: 1-10
Become imitators of me, just as I am of Christ 2 I commend you because in all things you remember me and you are holding fast the traditions just as I handed them on to you. 3 But I want you to know that the head of every man is the Christ;+ in turn, the head of a woman is the man;+ in turn, the head of the Christ is God.+ 4 Every man who prays or prophesies with something on his head shames his head; 5 but every woman who prays or prophesies + with her head uncovered shames her head, for it is one and the same as if she were a woman with a shaved head. 6 For if a woman does not cover herself, she should have her hair cut off; but if it is disgraceful for a woman to have her hair cut off or shaved, she should be covered.
7 For a man should not have his head covered, as he is God’s image+ and glory, but the woman is man’s glory. 8 For man did not come from woman, but woman came from man.+ 9 And what is more, man was not created for the sake of the woman, but woman for the sake of the man.+ 10 That is why the woman ought to have a sign of authority on her head, because of the angels.+
