My fro is gone!

I have been staying at my parents house for the last week and half and they have a soft water filter. I on the other hand do not! I am finding that my hair does not like the soft water!!! I have washed my hair twice and used the same products that I have always used and it just falls flat and lifeless. I can't wait to go back home and use my dirty city water again...I miss my fro!!! I want my full curly fro back and I don't ever want it to leave again! I even tried using a diffuser and nothing!!! Needless to say I am counting down the days until I go back home!!! So until then a pulled back ponytail will have to do.
