What is the impact of hard water on hair?

Hard water contains high levels of minerals, such as calcium and magnesium, which can significantly impact the hair. When hair is washed with hard water, these minerals can deposit onto the hair shaft and the scalp. This buildup may lead to hair feeling dry and rough, as the moisture balance is disrupted. The residue can also cause the hair to appear dull and lifeless, as it can inhibit light reflection, which normally contributes to shine.

Additionally, these mineral deposits can make it difficult for hair products such as conditioners and shampoos to penetrate and work effectively, further contributing to the feeling of dryness and lack of luster. As a result, many people with hard water find that their usual hair care products do not deliver the expected results, necessitating the use of chelating agents or specialized products to help remove mineral buildup. This phenomenon highlights the importance of understanding how water quality can affect hair health and appearance.
