“Excessive care about worldly matters is characteristic of an unbelieving and fainthearted person, and woe to us, if, in taking care of ourselves, we do not use as our foundation our faith in God, who cares for us! If we do not attribute visible blessings to Him, which we use in this life, then how can we expect those blessings from Him which are promised in the future? We will not be of such little faith. By the words of our Savior, it is better first to seek the Kingdom of God, for the rest shall be added unto us (see Mt. 6:33).”

"A scarf may be a small matter, but obedience often hinges on small things, small choices. My scarf is seen by men, but to me it signifies obedience to God, a way of living my womanhood. It is my feminine “I am” reflected outwardly. In putting on my head-covering I mean to say to God, “Behold your handmaiden, be it unto me according to Your word—Your will, not mine.”
"In Orthodox worship the angels were even more in evidence. The Divine Liturgy is full of references to the various ranks of angels, emphasizing our participation with them in the joyous worship of the Holy Trinity. St. John Chrysostom (d. A.D. 407), in a sermon at the Feast of the Ascension, spoke both of angels and the veiling of women: “The angels are present here...Open the eyes of faith and look upon this sight. For if the very air is filled with angels, how much more so the Church! ...Hear the Apostle teaching this, when he bids the women to cover their heads with a veil because of the presence of the angels.” Origen, another early Church Father, said, “There are angels in the midst of our assembly...we have here a twofold Church, one of men, the other of angels...And since there are angels present...women, when they pray, are ordered to have a covering upon their heads because of those angels. They assist the saints and rejoice in the Church.” Instructions for catechumens in The Apostolic Tradition, probably written in the second century by St. Hippolytus of Rome, include this: “Moreover, let all the women have their heads veiled with a scarf...” And St. Cyril of Alexandria, commenting on I Corinthians, wrote: “The angels find it extremely hard to bear if this law [that women cover their heads] is disregarded.”
"Mary, the mother of our Lord—and of the Church which is His Body—made our salvation possible by obeying God’s will. If she whom we hymn as “more honorable than the cherubim and more glorious beyond compare than the seraphim” is always seen in icons wearing her head-covering, it certainly cannot be a sign of “inferiority to men”
The Theotokos is encouraged as woman's best example and role model
As I wrote before I think a woman's outward modesty and obedience to God effects her family and children, so it's more than just men not seeing hair in church. The way a woman chooses to dress is an attitude of the heart.
