From the question What are the regulations governing (against) beards in space? we know that hair and beard length are not regulated on the ISS. For the most part pictures indicate both men and women keep their hair maintained.
I know when using electrical trimmers at home there are small pieces of hair, that gravity bring to the ground, and they get washed or vacuumed away. In the ISS they would just float around until someone inhaled them, or they got caught someplace.
How is hair maintenance managed on the ISS? Is trimming limited to only the head (i.e. is body hair below the neck line trimmed in space)?
