I am aware that women are required to cover their hair once they have been married. I was under the impression that it had to do with her husband being the only one to see and enjoy her, ie with tzinut. If a woman never marries, she never is required to cover her hair. But if a woman marries, and then either is divorced or widowed, she becomes available to marry again. Yet, I am told, she must continue to cover her hair. When I was married, although I was shomer kashruth and shabbat, I didn’t cover my hair. I’ve been divorced for more than thirty years. Does it make sense to begin now to cover my hair?
You should cover your hair unless you would like to remarry and feel this could interfere.
