Why do unmarried women wear head scarves?

A Muslim woman wears a hijab (head cover) in order to cover her hair. It is a requirement in the religion of Islam to do so. So when she wears it, she is obeying Allah's (Gods) Word in the Quran. It is also a outside expression of her personal relationship and personal decision between herself and Allah.

No one can order or force a woman to wear the hijab (head covering) or else she would be wearing it for the WRONG reasons.

However, a Muslim woman is required NOT ONLY covering her hair, but to wear modest clothes as well. And only have her hands and face showing. So no mini skirts, tight jeans, low cut tops etc. (she can wear those types of clothes WHILE in her home and when no male guests are in the family home that may see her)

The reason why she chooses to wear it, is to protect her privacy, and her beauty from those that are not worth to view it. (as in any male that is NOT her husband or family member) So she would wear it when she leaves the home, when photos are taken of her, or if guests come to her home that are male.

She still has hair styles and colours and highlights just like every other woman in the world does. But her hair and her natural beauty is her glory and her honour. She is valued and respects as a precious jewel.
