Anyone with long hair knows that it takes a long time to get it washed. In space, the lack of gravity — and restrictions on potable water — make a simple hair clean very challenging.
Luckily, we have astronauts to show us how it's done. Astronaut Karen Nyberg walks through the procedure in a recent video. Her long, blonde hair, which usually floated free in orbit during press conferences and chats with school children, attracted many comments during her half-year mission on the International Space Station in 2013.
"I've had a lot of people ask me how I wash my hair in space," Nyberg says in the video, "and I thought I'd show you how I do it."
The ingredients in space are apparently simple — no styling gels, no curlers. Astronauts also wipe themselves in space instead of using a shower, to save on water.
Nyberg uses a recipe of warm water, no-rinse shampoo, towels, and a comb. Standing her hair straight up in microgravity, she can be seen grasping a nearby floating drink bag.
"What I like to do is start by putting some hot water and squirting it on my scalp,” she says. “I have a mirror here so I can kind of watch what I'm doing."
