I suspect that most of the damage to skin and hair by the chlorinating agent
in
swimming pools is already done by the time you get out of the water.
The levels of chlorine, or hypochlorous acid, or whatever, in pools is
usually
in the medium low ppm range.
If you made up a 0.1-1% by weight solution of thiosulfate and rinsed
yourself with it,
it should be plenty enough to do whatever good you could derive from it, I
would
think.

I would go for shower. After thiosulfate bath you will be slightly smelly
– to be honest I prefer to smell of chlorine than of rotten eggs. Medicine
worse than the malady.
At least that’s what I remember from the time I was using thiosulfate in
the darkroom.

No, it concentrates in the tips of hair as it dries due to the physical
evaporation process.

No, showering or shampooing alone will not get rid of chlorine bound to
proteinaceous tissues and hair. You must chemically neutralize with the
thiosulfate. Then the sulfur will wash out with detergent.
