I sent this filtering showerhead to my daughter to use at college. She has very hard, chlorinated water and it was drying her hair out terribly. She loves it and says she noticed an immediate difference in her hair. It is easy to use. Just screw on and replace the old showerhead before you leave the dorms!
We have well water in our home and it seems to make a difference eventhough we have a top of the line water softner system too. Our naturopathic doctor recommended these filters to us. We own 3; we got one of each.
