Jewish women have their own unique role and rules in an orthodox Jewish family. The rules of Jewish women include modesty, family purity (the laws of Niddah), hair covering and much more. Women and girls are viewed as the backbone of the Jewish home.
Orthodox Jewish women are required to cover their hair by wearing a wig. Jewish law considers the hair a beauty of a woman, and her hair is not supposed to be shown in public after marriage. By covering her hair, the married woman makes a statement: “I am not available. You can see me but I am not open to the public. Even my hair, the most obvious and visible part of me, is not for your eyes.” The Orthodox Jewish woman can be proud of the way she looks without compromising her privacy. She has created a private space, and only she decides who to let into that space.
Some ultra-orthodox Jewish women shave their heads and wear only a kerchief (called a tichel) on their heads. It is a lot easier to cover a shaved head than it is to cover a full head of hair under a wig. Most Hasidic Jewish women wear wigs. Modern orthodox women might wear only a hat that covers only part of their hair.
