Personal hygene in space

It's time for another entry featuring a Discovery News in the spirit of Sleeping in space, which lay at the intersection of space and health.  Tonight, it's How Do Astronauts Shave In Space?

Personal hygiene becomes very difficult when there’s a lack of gravity. How do astronauts shave and brush their teeth in space? Trace breaks down the ways that astronauts take care of their bodies.

That's enough to make me look for a video about using a space toilet. SciShow has one that asks How Do Astronauts Do Their Business?

So how do astronauts manage to pee and poop in microgravity? And what happens to all of their waste? Do you really want to know? If you do, the answers are inside!

As Sulu would say, oh my, TMI!
