My hair went from shiny to straw in 3 weeks, check your shower filter
I moved to a new apartment in Columbus last month and within 3 weeks my hair felt like dry hay no matter what conditioner I used. Turns out the building has super hard water and my old shower filter broke. Once I swapped in a new vitamin C filter, the difference was night and day after just 4 washes. Has anyone else dealt with hard water wrecking their routine, or did you find a better fix?
