Space news: Hair wash mystery solved! This woman NASA astronaut shows how to do it right

This woman Nasa astronaut showed how she washes or shampoos her hair inside International Space Station in a video and reveals that they even drink that water later.

Here is some space news with a difference! Washing hair should be simple enough, but in space it requires the equivalent of rocket science to do it. Yes, living in space is a vastly different experience than living on Earth. For one, there is no gravity in space, or at least not the strong kind found on our Earth, which makes even the most basic and menial tasks such as putting food in your mouth difficult. So, imagine how tough washing your hair will be. Lack of gravity not just makes the hair spread out in all directions, it also turns liquid water into tiny globules that travel in all directions. Unlike on Earth, you cannot use a stream of water to wash off the shampoo from your hair. Now, a woman NASA astronaut has shared a video that debunks any mystery about how astronauts wash or shampoo their hair in space inside the International Space Station.

NASA astronaut Megan McArthur has shared a video on Twitter wherein she explains how astronauts keep their hair clean on the International Space Station. "Shower Hour! Astronauts can't take showers in space or the water would go everywhere, so I thought I would demonstrate how we keep hair clean on the International Space Station. The simple things we take for granted on Earth are not so simple in micro-gravity," McArthur wrote while sharing the video on Twitter.

In the video, McArthur explained astronauts washing their hair using a 'no-rinse shampoo that requires only a little bit of water'. This type of shampoo was originally developed for hospital patients who were unable to take a shower. In the video, the NASA astronaut starts by making her hair wet by using a tiny bit of water. She uses a towel to trap the water underneath it. She then combs her hair to evenly spread the water throughout her hair and her scalp. Next, she applies a no-rinse shampoo on her hair just like we do on Earth following which she combs her hair to spread it out evenly.

Now, on Earth, we usually wash off the shampoo by rinsing it under a stream of water. Since that isn't possible in space, McArthur uses a tiny bit of water and the wet towel to rinse the soap out of her hair. Finally, she dries her hair with the dry part of the towel.

"The air conditioning system will pick up the condensate both from the towel and from my hair and put that back into the water reclamation system," the NASA astronaut said in the video.

She also said that at present, the water reclamation system turn around 70% of the water used in washing her hair into drinking water and NASA researchers were working with technology demonstrators to get that number up above 95%.
