When you're an astronaut on the International Space Station, you don't have a lot of the comforts you have on earth. So, you have to get real creative about how you do things, like washing your hair, for instance. Astronaut Karen Nyberg demonstrates how she keeps her hair looking good while on the ISS.

This should make you think twice about how hard it is to do your hair every morning on earth. It may also make you think twice about becoming an astronaut.

I hate to say it, but my hair stands up straight like that every morning and I have the benefit of the earth's gravity.
