Explanation: How can you wash your hair in space -- without gravity [4] ? Long
a bother for space-faring astronauts, Karen Nyberg [5] , a flight engineer [6]
 on the International Space Station [7]  (ISS) in 2013, gave a tutorial. Key
components are a squirt package of water, no-rinse shampoo [8] , and vigorous
use of a towel [9]  and comb. Even so, the featured video [10]  shows that the
whole process should take only a few minutes. Residual water will eventually
evaporate [11]  from your hair [12] , be captured by the space station's air
conditioning system, and be purified into drinking water [13] . After
returning from a total of 180 days in space, Nyberg [14]  has worked for NASA
in several capacities including as the Chief of Robotics [15]  branch.
