No. However water that is too hot may make your scalp dry.
You run out hot water because you must have a small water heater. A water heater gets water, and heats it up, so if you have a small one, then once you use up all the hot water, you need to wait a while for the heater to heat up more.
Typically, if you have hot water that is white, you have a water softener in your home. The water softener adds a small quantity of salt to the water to make it feel softer to the skin. This tends to break down some of the minerals in the water and also make it less likely to etch glasses in a dishwasher. The water softener is typically not plumbed into the cold water, and this is why the cold water remains clear.

I don't think that is possible. How can "hot" make "cool" water "cold"? (also, 'hot ice' is boiling water)
The hot water pipe feeding the two is too small, either by build up inside the pipe (very common with steel lines), or because it was too small to begin with. Or a shutoff valve is partially closed (maybe at the hot water heater?)
