Female astronauts choose to keep hair down in space

Female astronauts, like Sunita Williams, often keep their hair down in space because microgravity prevents it from falling into their faces. This allows for easier hair washing with no-rinse shampoo and towel drying. The International Space Station's ventilation system helps dry hair by directing airflow. Personal preference also plays a role, as some astronauts prefer to wear their hair down while in space. Astronaut Karen Nyberg demonstrated her hair washing routine in 2012, using warm water, no-rinse shampoo, and a towel. She explained that the evaporated water is condensed and turned into drinking water on the space station.
