Man is to have his head uncovered during the church services because as God's vessels they are to function with the gifts of the Holy Spirit. If they cover their heads they are shaming what God has instructed them to do. Because God created man in His image therefore having the head uncovered represents the position men are to assume in the meetings of the church, leadership.
The glory of the man should not be made visible because God is to be glorified in our worship. Because the glory of the wife is her hair she humbles her God given glory with the cloth covering her head so as not to let man's glory be visible during the worship service.
The application of the hair is for married women and not all women. Because only wives are to be in subjection to their husbands and single women are not in subjection to a husband.
