Ever wondered how astronauts keep themselves clean when living in space?
Well, NASA astronaut Karen Nyberg has given us a glimpse of how they manage their personal hygiene in a video she posted on YouTube and Twitter.
"I've had a lot of people ask me how I wash my hair in space, and I thought I'd show you how I do it," said Nyberg.
In the video, Nyberg demonstrated how she washes her long hair using just a small pouch of warm water, a bottle of no-rinse shampoo, a towel and a comb.
Nyberg, a mechanical engineer-turned-astronaut, is currently living aboard the International Space Station as part of Expedition 36.
