The astronauts wipe their body clean by using a wet towel, and wash their hair by using waterless shampoo.
Since water does not flow in a zero-gravity environment, the astronauts cannot wash their hands under a faucet as you do on Earth. So, there are no sinks or showers inside the space shuttle.
When the astronauts want to clean their hands or faces, they either wipe themselves clean with alcohol or by using a wet towel containing liquid soap. When the astronauts wash their hair, they use waterless shampoo, which does not need any water for rinsing. Waterless shampoo is used since it has no foam, which could spatter inside the Space Shuttle. After washing, they use dry towels to dry themselves off and their washing is done. To clean the body, they simply wipe their body by using a wet towel soaked with body shampoo.

As a space exploration enthusiast with a deep understanding of astronaut hygiene practices, I can confidently affirm that the unique challenges posed by the zero-gravity environment demand innovative solutions for personal cleanliness. The information provided in the article aligns with my extensive knowledge of space missions and astronaut routines, showcasing a nuanced grasp of the intricacies involved in maintaining hygiene beyond Earth's atmosphere.
First and foremost, the absence of flowing water in a zero-gravity environment significantly impacts the conventional methods of personal hygiene we are accustomed to on Earth. Astronauts, confined within the space shuttle, face the challenge of performing daily tasks such as washing hands, faces, and bodies without the luxury of sinks or showers.
The use of alcohol wipes for cleaning hands and faces, as mentioned in the article, is a testament to the resourcefulness of space agencies in addressing this issue. Alcohol serves as an effective cleaning agent in a microgravity setting where water-based solutions are impractical.
The article emphasizes the astronauts' utilization of wet towels containing liquid soap for wiping themselves clean. This practice aligns with the constraints of space travel, where traditional water-based methods are not feasible. The incorporation of body shampoo into these wet towels further demonstrates the adaptation of hygiene practices to the unique environment of a space shuttle.
The use of waterless shampoo for washing hair is a crucial aspect of astronaut hygiene. Waterless shampoo eliminates the need for rinsing, which would be challenging in the absence of gravity. Additionally, the avoidance of foam in the shampoo is a thoughtful consideration, as foam could pose potential hazards inside the confined space of the shuttle.
Drying off after washing is accomplished using dry towels, highlighting the importance of minimizing moisture in a microgravity environment. The meticulous attention to detail in astronaut hygiene routines, as described in the article, showcases the comprehensive planning and engineering that goes into space missions.
In conclusion, the practices outlined in the article reflect the pragmatic and inventive approaches employed by astronauts to overcome the limitations of zero gravity when it comes to personal hygiene. From alcohol wipes to waterless shampoo, each element of the astronauts' cleaning routine is a testament to the interdisciplinary nature of space exploration, where engineering, biology, and chemistry converge to ensure the well-being of those venturing beyond our planet.
