I wore a wig for work several years ago and really had to pin it in with kirby grips. I don’t like clients touching my hair and actively discourage it so it didn’t get ‘wrecked,’ but what I did find, is it made me so hot, like I had a hot water bottle on my head.
Mine was a short wig. I wouldn’t want to imagine what working in a long one would be like, although I’m sure other ladies get on fine with them.
My concern with a long wig would be if got smelly when giving BJs with all the saliva and dangling around client’s privates.
