It seems like powdered wigs were extremely popular among the upper class for a considerable period of time but eventually fell out of favor. I know that courts in some countries still use them for what I'm guessing are traditional purposes, but why did they fall out of favor?
Hi there, I am not discouraging anyone from giving you an answer, but I think you'd enjoy some of the previous work that people did on here adressing the wig fashion.
This one by /u/colevintage is wonderful. Pay no mind to it being an April Fools answer, it's accurate with the added bonus of being written in character:)
/u/colevintage again and /u/chocolatepot talk about powdered wigs in here as well and /u/cecikerk talks about them here
