How Hard Water Affects Your Hair and Skin:

Causes, Effects, and Solutions

Our shower water is often the root cause of many of our hair and skin issues. Hard water, which contains higher levels of calcium or magnesium, can significantly impact the health and appearance of your hair and skin.

Is Hard Water Bad for Your Hair?

Yes, hard water can be detrimental to your hair. Nearly all of our water contains chlorine, heavy metals, and other contaminants, leading to various issues we’ve all been trying to solve, such as damaged hair. Hard water can cause hair to become brittle, frizzy, dull, and prone to split ends and breakage. The mineral buildup prevents the hair from absorbing moisture from products like conditioner, leaving it drier.

What Is Hard Water?

According to Tasha Stoiber, Ph.D., Senior Scientist at EWG, “Hard water, or water that contains higher levels of calcium or magnesium, can cause skin/scalp dryness or cause the skin/scalp to be more sensitive.” She explains that soap and shampoo don’t work as effectively with hard water, leaving a residue on the skin and hair.

Adverse Effects of Hard Water on Hair

  1. Blocking Moisture: Mineral residue from hard water clings to your hair as the water evaporates, blocking moisture absorption. This can lead to frizz, dullness, and reduced elasticity and shine.
  2. Promotes Split Ends and Breakage: Hard water breaks down the outer protective cuticle, exposing the inner cortex of the hair. This causes weak points along the hair shafts, leading to breakage.
  3. Prevents Effective Cleansing: The minerals in hard water can make it difficult to form a lather, hindering effective cleansing of the hair and scalp. Soap reacts with calcium in hard water to form a soap-scum residue.
  4. Makes the Scalp Itchy: The residue left behind by hard water can irritate the scalp, making it feel dry and itchy.
  5. Interferes with Hair Color: Hard water can cause color-treated hair to fade faster, and blonde shades tend to appear brassier over time.
