I was looking into this and found this link http://bible.cc/1_corinthians/11-6.htm about covering head in Christianity. I was amused to see so many translations and all are authentic for Christians. New international version, new living translation, English standard version, new American standard Bible, King James Bible, King James 2000 
Bible, Darby Bible, English “revised” (lol) version and many more.
More I read other religions, more Islam make sense to me
