Me too, I haven't laughed so much in ages. It made me think of the Cybermen from the 80s or maybe those sorts who wear tinfoil on their heads to stop the government beaming things into their brains!
Genuinely curious though - what are the headphones for? Do you listen to music while grilling your scalp? Can't help but wonder what effect this sort of thing might have on the user's brain.
I appreciate that people can lose their hair for all sorts of unfortunate reasons, but, to me, it's sad that some will have been made to feel so bad about it that they have to resort to things like this.
