Municipal hard water contains minerals; specifically, calcium, magnesium, iron and chlorine, which can dry your skin. Chlorine and minerals drying on the skin can clog pores and cause flaking and itching. Hard water also tends to react with soap to form salts, which can also remain on the skin.

Here are some signs that hard water is affecting your hair:

  • Hair that feels filmy, straw-like dull and limp, and ultimately less pliable
  • Color-treated hair that fades quickly, leading to more frequent color treatments and further damage to hair
  • Residual shampoo in your hair
  • Hair that’s hard to lather with shampoo
  • Thinning hair and breakage caused by hard water
  • Hair loss
