"Zero-G Haircuts: Chinese Astronauts Take Styling to New Heights on Space Station"
Chinese astronauts aboard the Tiangong space station were seen giving each other haircuts using a vacuum-based haircutting device. The device prevents loose hairs from floating around the station and causing issues with its equipment. Similar to the system used on the International Space Station, the vacuum attachment on special clippers collects the hair clippings to prevent them from floating freely.
