This is really a neat video because we always have a lot of questions regarding space.....living in space.  You know, not questions about performing the work-tasks the astronauts have to do, but questions about normal human needs...personal hygiene.

Living at the International Space Station, the astronauts have a job to do just like everyone on Earth, and they have to take care of themselves the same way the rest of us do. They just have to do it differently. Astronaut Karen Nyberg shot this video to show how she washes her hair.
