What? The diuretic? I've not heard about using that for hair loss before... You have to increase what you are drinking. The harm you can be doing to your kidneys is huge love. You are asking them to push out more water when you aren't taking in what you would lose every day just by being alive... They can only cope under that kind of strain for so long. I'm sorry to sound harsh, but I know how horrible kidney disease is and how bad it can get when they hit kidney failure....
