Hard Water (makes my life harder)

There's something in the water.

Every time I take a shower, my hair seems to get dirtier. It's a tangible feeling, not just my own paranoia about my hair. It's losing its luster, it's shine. It's limp and changing to a duller color of brown instead of the subtle red highlights of my former life (seems so long ago, though only a week.) I'm pretty sure it's the hard water.

This is annoying. Should I talk to my landlord? Even the cheapest systems that you can buy to soften your water are around $300. Is that asking too much?

If you know anything about tablets that I can stick in my shower head, please let me know. The Internet has been worthless to me in this endeavor except to deprive me of hope....
