Why do Jewish women wear wigs?
According to Jewish law, married women are required to cover their hair which is earlier referred to as the "law of the Jewish People", but subsequently it is known as the "law of Moses". Women usually cover their hair with a snood, wig or scarf, but some women use hats also for the same purpose.
However the practice of covering hair by women by any of the above practices is being debated vociferously. Some of the early Rabbis encouraged the use of hair coverings, but some have expressed their disapproval of the practice. Even orthodox modern women, who belong to a generation before, have left the habit of covering their hair except when they are in the synagogue. But the practice of covering the hair has been voluntarily opted by the present generation of women, which is quite unusual considering the hectic pace of modern civilization. They believe to convey modesty in their appearance, which is after all one component of moral attitude. It is left to the individual women living in a particular location and atmosphere to decide on whether to cover the hair or not. It is being insisted more as a symbolic gesture of feminism rather than anything else.
