The caption has a hilarious dangling participle:

"Long a bother for space-faring astronauts, Karen Nyberg..." Well, shame on her, being such a persistent bother to her space colleagues!

And if you place freshly washed clothes in the airlock, will they come back freeze packed,
or will the vacuum completely desiccate/dry them ?

(if water can even be wasted in this way ?)

Wow, her hair in this video really reminds me of the Martian menace, "Calvin", in the movie, Life (particularly at about 2:43, when she just starts running).

This is probably true, but it's not because of air flow. It's just the lack of gravity. You see in both videos there are somewhat loose objects, wires, etc. in the room, but they aren't fluttering or moving about. Please don't ask me to watch it again unless you want to point out some specific evidence that backs up what you're saying.

She had the convenience of a high air flow chamber to draw her hair, and spilt water, away from her face, and no doubt to dry it.
Bit like standing in front of a fan, or a hair dryer!
Why do you say that? There are small fans sucking in air and debris, but she doesn't appear to be in any kind of "high air flow" chamber to me. Those little square grid things behind her are for ventilation, and you don't see things flowing toward them.

What is the number line on the wall to her left used for? The numerical palindrome.

Certainly, some astronauts have chosen to do this. It's reasonable. But nothing makes it particularly necessary. It's obviously not that difficult to wash your hair. It doesn't consume much time. And water in the ISS is not wasted. Whatever you use to wash your hair is back in the system in short order. It's not like they vent their dirty water into space!

It was developed for the Earth-bound. Useful for camping trips.

I would shave my head before going up, then keep it as short as possible while on ISS. It just seems easier and far more practical.

Aren't their duty tours 6 months? Hair would be pretty long by then!

I would not want to be minding my own business elsewhere in the ISS and suddenly get splashed in the face by a roaming blob of water from someone's hair-washing -- or worse!

What? She put it that way before the video started. Clearly it's easier to work with up like that, or she wouldn't have done that.

Perhaps we could equally ask how you take a shower while in space - or have a bath (!) in zero g.

Or do your laundry. ?
And if you place freshly washed clothes in the airlock, will they come back freeze packed,
or will the vacuum completely desiccate/dry them ?
(if water can even be wasted in this way ?)

Even brushing your teeth must be interesting, how do you persuade water onto the toothbrush.
Coffee cups are probably redundant up there too ?
Etc etc.

Image How to Wash Your Hair in Space

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