Literature associated with Head Kenzan, a Japanese scalp massager, assures the reader that the yellow plastic spines “hit upon that perfect balance of not-too-hard and not-too-soft.”
I think I’ll stick with the classic brass-tentacled head orgasmatron, myself.
Seriously, if you carry this on the streets in Britain, you’ll get thrown in jail.
Head Kenzan Japanese Massager [Japan Trend]
The best part of getting your hair cut, IMHO, is the pleasurable scalp masage as they prepare your keratinised protein filaments for pruning. If this stimulates the nucleus accumbens in a similar fashion, I can see it being quite addictive!
I have one of those copper octopus-looking head massagers and it’s amazing. This seems to be a similar concept.
Care to elaborate on your small comment?
If you buy a couple dozen of them, you can fashion a makeshift iron maiden for more intense pain/pleasure!
