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.

Did you click the link I gave and read the article I summarized?

A page by a seller of water heaters (certainly not an unbiased source) talking about money cost (not what I was talking about). In particular, it does not detail the energy cost (no matter what type of energy) that goes into transporting the energy to your house (that is, the very point I was talking about).
The Tao of math: The numbers you can count are not the real numbers.

Okay, I spent some time and effort, did some research, posted a link to the best one I found which happens to agree with other references, the data looks good, makes sense, etc. It's an Angie's List award winner, in CA, the most energy-conscious and regulated state in the US (as far as I know and have heard). I don't see any reason for them to lie and lose their reputation, get sued, etc.
You don't like it? Please do some research and post your results and I'll check back.

You found something in units (dollars) that aren't relevant. If it's $100 to kill a dog or $2000 to fly to Disneyland, do you kill the dog? His criticism - that your data isn't useful data to an environmentalist decision - is valid. You didn't give useful data. Stop whining. You posted "the best one [you] found" and it was bad. Do better or cede the point.

Who the hell are you? I owe you data? I owe anyone data? I spend time and effort to contribute here and you're whining about it? All you do is troll me whining about the data and link I gave, you give NOTHING but your troll? Go back under the bridge. Time for this site to eliminate ACs.
