We're on a deep well, so our water is quite hard which means it's basic or low pH.
Our rainwater is acidic, but some places have more acidic rainwater than others, so if your hair responded well, since I find acid helps to cut grease, that would make sense.
Dehumidifier water is neutral or pH 7. It certainly shouldn't do anything harmful. We regularly add it to our washing machine along with some of both of the others to help clean our clothes more easily, based on what's easily available.
I'd suggest you try it and see how it goes (and report back, as I love to hear the results of real-life experiments!)
