astronaut Karen Nyberg this week took it upon herself to continue the fun, posting a video on YouTube (below) describing the bizarre but perfectly understandable steps you have to go through to get your hair clean when you’re located 220 miles above the planet. Really, dealing with water in a weightless environment has never looked so darn difficult.To wash out all that pesky space dust, Nyberg says she uses the same kind of things you use at home – ie. water, shampoo, a towel and a comb. So far, so normal.
As she begins to squeeze water from a bag, however, things immediately get tricky, with Nyberg having to catch blobs of water as they float away from her. With her hair standing on end, she does her best to rub in the water before adding shampoo.“Without standing under running water, you need to use the towel a little bit to help get some of the dirt out,” Nyberg explains.
The fate of the water blobs

Once her hair has reached “squeaky clean” status, Nyberg explains what becomes of the water in her hair and all those blobs she couldn’t catch.“As the water evaporates from my hair, it’ll become humidity in the air,” she says. “Then our air-conditioning system will collect it into condensate, and our water processing system will turn it into drinking water.”
