Watch: How to wash your hair in space

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).
