When I moved into my new apartment, I instantly noticed how bad the hard water was. After drying my hair, it would feel greasy on my scalp and just generally not clean. I also lighten my hair and after a few months I started noticing it looking really brassy. I've been using the Malibu C Hard Water Wellness Remedy for about two and a half months and it's the only thing that has actually helped! So glad I came across this product, my hair actually feels clean and looks way less brassy.
