The 13 Best Hard Water Shampoos for Healthy, Shiny Hair

Look for products labeled with words like “hard water” and “clarifying,” says Haliti, as these should indicate that the formula removes dirt, impurities, and mineral buildup. She also recommends opting for “shampoos with moisturizing ingredients such as natural oils, shea butter, or glycerin to combat dryness caused by hard water.”

Additionally, Moser suggests looking for chelating shampoos, which contain ingredients that bind to and remove heavy metals from the hair, as well as “copper removing” formulas. “When I see ‘copper removing’ on a label, I know that it claims to remove the green cast from aging hair color,” he says.
