What can hard water do to hair services?

1. Improve the effectiveness of shampoos

2. Decrease shine and alter texture

3. Make hair easier to manage

4. Enhance color retention

The correct answer is: Decrease shine and alter texture

Hard water contains high levels of minerals, such as calcium and magnesium, which can have a significant impact on hair during various services. The presence of these minerals can lead to a decrease in shine, making hair look dull and lifeless. Additionally, hard water can alter the texture of hair, leaving it feeling rough or stiff. This occurs because the minerals can deposit on the hair, creating a film that prevents moisture and product absorption, which ultimately affects the overall appearance and health of the hair. While the other options suggest benefits that hard water does not provide—such as improving shampoo effectiveness, making hair easier to manage, or enhancing color retention—the reality is that hard water often complicates these aspects by hindering product effectiveness and overall hair manageability.
