Hard water is an issue that many homes deal with, and it can significantly change the condition and appearance of your hair. High concentrations of minerals found in hard water can leave residue on your hair that makes it look lifeless and drab. It may also result in buildup in your pipes, which could decrease water flow and cause other issues. The good news is that there are shampoos available that are made specifically to counteract the effects of hard water, giving your hair the greatest possible look and texture.
