Hair and Pizza Crust

So as I previously said, I am in Kentucky at the moment and I think I have concluded something.  You know how people always say it's the water in NY that makes the crust for pizza and bagels so good.  I even read about some pizza place in LA that the owner has NYC tap water shipped to the restaurant to make the dough.  

I think the same substance that is in NYC tap water, also causes your hair to become a hot mess when you sleep on it.  I have fairly long hair and when I am in NYC, every morning, my hair looks like squirrels nested in it.  It is all tangly, curly, knotty and just plain ole messed up.  In KY that never happens.  I wake up, and since my hair retained the shape it had the night before, sometimes I don't wash it.  Sure it gets a little greasy but it still remains its shape.

Has anyone else noticed this phenomenon..?

I conclude that there is something in NYC water that causes your hair to get tangly over night.
