Final answer:
Muslim women might cover their head or hair for religious reasons. In some countries it is required by law, while in others it is a personal choice based on cultural identity or religious beliefs.
Step-by-step explanation:
Muslim women might cover their head or hair for religious reasons. In some countries with Muslim-majority populations, such as Iran, Saudi Arabia, and Afghanistan, the law requires women to veil their heads and/or faces in public. In other Muslim countries, women can choose whether to do so. Many Muslim women voluntarily choose to wear veils or headscarves as a symbol of their cultural identity or religious piety. Additionally, some Muslim women living in the West may choose to cover their heads and faces due to personal religious beliefs.
