If you ride slowly on cycle paths or in Copenhagen, you can get by without one. Over 10kph/6mph and in mixed traffic, just cope with helmet hair. Brains belong on the inside!
When the kids tell me helmets don't make a big difference, I have a collection of crushed ones that I like to wheel out. And photos of my head after the one time I didn't wear one in Sydney (literally one time; the unluckiest few hundred metres of my cycling career!) They come around to my way of thinking then if they are planning to do any road riding.
