Last week, astronaut Karen Nyberg shared via video how she washes her long hair in space. Since about 1.5 million people have watched it, NASA decided to give equal time to the bald guy in space, Luca Parmitano. As I stated last week, obviously, Parmitano uses a different method than Nyberg. Note it takes about 3 minutes for Nyberg to wash her hair, while it takes Parmitano less than a minute.
