If you ever get the chance to head to outer space, you might want to consider a hair cut before taking off. NASA astronaut Karen Nyberg, a crew member on Expedition 36, recently posted a YouTube video explaining how she washes her hair during her stay on the International Space Station (ISS).
Even as she squirts hot water onto her scalp, you can see it floating away, towards the ceiling of the zero-gravity ISS. Her hair stands straight up throughout, in a look only Medusa would envy.
