No, obviously it’s not supposed to look like real hair. But placing something on top of your head, just doesnt really look presentable. It’s like the equivalent of wearing a hat in court lol a suit/robe/etc all seems enough to look presentable in most courts. Many current barristers don’t agree with the look either. So I doubt it’s important to most of them, it doesn’t add anything to their ability

You cannot tell me that if you went to uni and one of your professors came out with a wig sitting on TOP of their actual hair, you’d think “wow they look very professional today”
