This video and the other one from Fulan Fulanah (https://vk.com/video-76804306_456239893) are both amazing and maddening.

It's clear that Fulan is one of us. I give him major props for putting these together!

My biggest question is that in both videos the woman or women already have long hair (or at least wigs). Why don't they use their own hair on the guy?

Dolls, wigs and ponytails seem to me to be mostly substitutes for when a guy doesn't have a woman who can give him a hairjob, though I will admit that a hair enthusiast may also want other lengths and textures that his partner doesn't have.
