Wigs are so much a part of British criminal courts that if a barrister doesn't wear one, it's seen as an insult to the court.

Most are handmade from 100 percent horsehair, though there are synthetic versions available today, too. Horsehair wigs aren't cheap, either, especially when they're handmade and combine an ages-old craft of styling, sewing and gluing. A judge's full-length wig can cost more than $3,000

Those who couldn't afford the best garb but wanted to look the part wore wigs made of hair from goats, spooled cotton or from the hair of human corpses
This is the stupidest and most disgusting thing I've read today, thanks.
Hair is already dead and animal hair (can't remember which animal) is also used for the best brushes used for painting.
IMO as long as the hair is washed which it obviously is, it's not really disgusting.
And honestly if you are referring to the animals (which you are, otherwise you wouldn't say "beings") they likely wouldn't have been born in the first place if humans didn't like their hair.
