Thats the point that Paul was making in
1Cor 11. It would be better for a women to even be shaved bald or have cut hair, rather than have a Pentecostal UpDo. Because with the UpDo her head is not covered, and she has not adorned herself with modesty.
If that is ashamed she should have long hair covering her head.
To imply that you ears and neck are not part of your head is simply false.
In Greek the head is that form of the body most readily taken hold of: This includes the neck.
