HOWTO wash your hair in space
NASA flight engineer Karen Nyberg shot this video aboard the International Space Station, showing how she washes her hair in space. I love the escaping, mischievous blobs of water, and the awesome spectacle of Nyberg's hair rising up in a might, vertical pillar. Best part, though, is how the space station itself is a huge hair dryer that sucks the moisture out of her hair and recycles it into drinking water.
"And now as my hair dries, as the water evaporates from my hair, it will become humidity in the air, and our air conditioning system will collect that into condensate," Nyberg said. "It won't be long and our water processing system will turn that into drinking water."
One last run through with a comb ensures no snags or snarls, she added.
"While it dries, I just let it stay free. I don't put it back into a ponytail while it's drying," Nyberg said. "And that is how I wash my hair in space on the International Space Station."
