RE: Wigs

I have not been checking Dwayne's blog of recent. I have once seen a female pix in one of his post but I didn't take it very serious. Thought it was just his random posts! Until I came across this one today,the first sentence caught my attention. Is Dwayne now plaiting hair? Or is someone else now in charge of the account?
I kept reading and then went back to see other posts. That's when I realized what was going on😄

My question:
Are those wigs made from human hairs or other materials?
