Cyclists may not need to sacrifice another good hair day by wearing the traditional helmet.
The protective gear is still a must in New Zealand, but two Swedish inventors have found a way to make it invisible.
Anna Haupt and Terese Alstin have created the world's first invisible helmet called Hovding - a thick collar with an airbag hood underneath that deploys on impact.
The pair thought of the idea for their thesis at Lund University in the spring of 2005, when the Swedish government was looking at making helmets mandatory.
They wanted to make a helmet so attractive that cyclists would voluntarily start protecting their heads on the roads without the law ordering them to do so.
The helmet uses sensors which pick up the abnormal movements of a bicyclist in an accident and send a signal to a gas inflater that inflates the airbag within 0.1 seconds.
The airbag, made of ultra-strong nylon fabric, then shapes around the cyclist's head like a hood.
The collar is covered by a removable shell that you can change to match your outfit.
The helmet is switched on and off using a zip at the front of the collar and uses rechargeable batteries.
The invisible helmet cannot be bought in countries outside of Europe yet.
