VIDEO: How do astronauts cut their hair in space?

Although there aren't many people who visit you in space, it is still important for astronauts to groom themselves. However, have you ever wondered how these people carry out a task as simple as getting a haircut in space?

China's Shenzhou 17 astronauts, including mission commander Tang Hongbo and rookie crewmates Tang Shengjie and Jiang Xinlin, have been assisting each other with grooming tasks during their on-orbit duties.

A recent video released by China Manned Space Agency (CMSA), shows Tang Shengjie cutting the hair of his colleague Jiang Xinlin using a smart device that also acts as a vacuum cleaner. 

According to Space.com, the device which has long been used on the International Space Station, uses a cut-and-vacuum system to remove hair from the space station, reducing the risk of clogging its hardware.

The footage also shows Tang Hongbo using special shower caps to wash his hair.

The astronaut rubs the first shower cap, containing shampoo, into his hair. Then, he rubs the second cap, which contains water, on his hair to clean and rinse it, which is then dried with a towel.

The Shenzhou 17 arrived in Tiangong on October 26, and a few days later the crew took over the station from the Shenzhou 16 mission crew, who were leaving after more than 50 days in orbit.

Moving equipment outside the space station for experiments and maintaining science facilities for long-term research have all been part of their daily activities.

The astronauts also brought back some breathtaking vistas from their orbital position.

For about half a year, the astronauts will be stationed in Tiangong and are expected to receive the Tianzhou 7 cargo resupply mission in January.
