How come metal wigs never took off as a fashion accessory? They're shiny, long lasting (barring rust), work brilliantly as a hard hat, available in different styles (the one being modelled here is in a rather attractive beehive with parting) and you can decorate them yourself.

Okay, you'll never be able to look down without falling over and fridge magnets will suddenly become a nuisance but that's not many downsides.
