Hair covering - Why?

i have been having a discussion with a few women, all married, and we have come to a stand still about something. one of us said that we cover our hair so that it stays something special to our husbands. is that correct or is there even any basis for such a statement?

Married women should cover their hair because Hashem said so in the Torah. In addition to that there are many benefits to the wife, the husband and to the family unit from this mitzvah, one of which is the fact the wife doesn’t share her intimate beauty with others but with her husband, that strengthens the bond of love and intimacy between the wife and her husband.
