When you hear about businesses with a high environmental impact or activities with a high carbon footprint, you are probably more likely to imagine heavy machinery, engines and oil rather than hairdressing. Yet hairdressing, both as a sector and as an individual activity, can have a massive carbon footprint.
Hairdressing uses high levels of hot water, energy and chemicals. Similarly, in our homes, heating hot water is typically the most energy intensive activity. For the cost of a ten-minute shower that uses an electric immersion heater, you could leave a typical television on for 20 hours.
So while it helps to turn lights and appliances off, the real gains in terms of reducing energy usage are in slashing our use of hot water. A quarter of UK emissions are residential and, of those, the vast majority come from running hot water. The longer it runs and the hotter it is, the more energy intensive (and costly) it is.
Mostly the hot water used carries a high carbon footprint, but the chemicals in shampoo don't help either.

You are only expanding on my proven point. The premise was that we need to revel in our own filth in order to satisfy the Green Nazis because heating water is such a horrible eco-disaster. TFS is clearly bullshit. I'm surprised they aren't railing about wasting water too. That's a common theme among the enviro-gestapo. The next step will be to have humanity huddling in a dark, unheated homes because banishing showers really wasn't our "most energy intensive" activity after all.

I have no idea if you're the same AC who trolled me, but you don't quite sound like him. You make really good points. My take, if I'm grasping the situation and if this is what you're saying, is that some people will never be happy. They seize a cause and go at it no matter what. They won't compromise nor listen to anything or anyone else. Egos are growing faster than anything else on earth.
I forgot to add above: it's pretty easy to reclaim waste "gray water" heat- sinks, laundry, shower, etc., before sending it out to the sewer.
