Astronaut Karen Nyberg is the current flight engineer for the International Space Station, a doctor of mechanical engineering, a mother, and the 50th woman ever to travel to space. She also has fantastic hair -- and as this video shows, it's not easy staying pretty in zero gravity. Watch as Dr. Nyberg demonstrates how astronauts shampoo their hair on the ISS.
It may be surprising that astronauts use water to wash their hair in space. But as Dr. Nyberg explains, any water used for hygiene will eventually be sucked up by the space station's air filtration system and turned into drinking water.
For science fans who still miss the entertaining and informational videos from former mission commander Chris Hadfield, it seems like Karen Nyberg is picking up the slack. We look forward to more exciting videos showing off life in space.
