Alternately…just cut your hair 🙄
It’s actually her scalp that she’s washing.
@wonderofscience Making the switch from liquid to bar shampoo was challenging; it took three or four washes to get it right. But THIS??
It's unlikely I'll ever have a chance to live in zero G, but if I do I'm getting a buzz cut before I leave Earth.
@wonderofscience I just don’t get how we haven’t mastered the idea of showers in space. Make water spray out the front, have an air intake at the back that goes to a condenser/dehumidifier…. To dry off… Compressed air, like a human sized Dyson air blade.
I’ve been camping and not showered for a week or two… But I could always just dunk my head in the river, even if it was “brisk”. I can’t imagine not showering for months at a time.
@JustinDerrick @wonderofscience
I'm sure we could, but is it worth the engineering effort and water consumption? People have been giving themselves sponge baths for centuries. They work as well in space as on the ground.

Economical use of ressources you can learn from ISS! Beginning with using towls for several times. And with recycling of waste water and even urine to drinking water 😎.
