Hey Tamika
If you are still looking for a shower filter, I'd suggest this website
http://www.solutionsforhealthyliving.com/
I got one that cost about $35.99 ( I can't remember the brand) and the filter last for a year for a family of 4 (and I'm the only one who uses it, so needless to say I haven't replaced the filter yet.
Four years ago when I went away to school in Philly I discovered how bad hard water can be for your hair (it made my hair maaad dry and it always felt like it had a coating on it- and it completely chewed up my dyed ends
). My hair could not handle the huge difference between Philly H2O and NYC H2O (believe it or not NY has pretty good water in comparison to a lot of other places) Well in less that a month of using the filter, my hair did a complete 180- it was soft again and would respond better to my products, and I stopped wasting so much money on shampoo (b/c it takes a lot of shampoo to get your hair clean when you have hard water)--- Long story short, don't hesitate to get a shower filter, it saved my hair for sure
