Footage of an astronaut washing her hair on the International Space Station is blowing peoples minds

Since many of us won't get the chance to go to space, we’re still curious about how astronauts handle everyday tasks up there - like, how do you cry?

Luckily the internet is filled with content to answer our undying questions.

NASA astronaut Karen Nyberg demonstrated how she washes her hair in space.

'I've had a lot of questions about how I wash my hair in space and I thought I'd show you how I do it,' Nyberg said on her video.

She showed the tools she uses to do so including a bag of warm water, no-rinse shampoo, a towel and a comb.

Nyberg starts by squirting warm water onto her scalp: 'I have a mirror there so I can watch what I'm doing.'

She added: 'Then I just work the water up through to the ends of my hair.'

Next, she applies her no-rinse shampoo to her scalp.

'Rub it in again, working it out to the ends,' she explained.

Nyberg mentioned the job being a little easier with the help of a comb to brush the shampoo through to the ends.

After that, Nyberg takes the towel for a bit of extra scrub.

'Because without standing under running water, you need to use the towel to help get some of the dirt out.'

To get rid of any excess shampoo, Nyberg uses a bit more warm water, saying: 'It's called no rinse shampoo but I think it's best if you use a little water with it.'

Grabbing the dry part of her towel to dry her hair, she describes the ISS only having a limited number of towels so the crew have to 'use them wisely.'

Finally, she gives her hair one last combo through before leaving it to dry.

But, here's the cool part.

Nyberg explains the process of what happens as her hair dries in space.

She added: 'As now as my hair dries, as the water evaporates from my hair, it will become humidity.

'And then our air conditioning system will collect that into condensate.

'It won't be long and our water processing system will turn that into drinking water.'

People have been surprised to find this content on their YouTube algorithm but at the same time, impressed by Nyberg's process and limited water used.

'This was by far the coolest video I have ever seen on shampooing hair!' one comment read.

'I've never seen someone use like a couple drops of water to wash their hair. So impressive,' another user wrote.
