What does a pH-balanced shampoo help maintain in the hair?

Color
Moisture
Natural oils
pH level

The correct answer is: pH level

A pH-balanced shampoo helps maintain the hair's natural pH level, which is typically 4.5-5.5. This is important because a balanced pH level helps keep the hair’s moisture and natural oils in balance, making sure the hair stays healthy and nourished. While color and moisture are important for hair health, they are not directly affected by pH balance. Using a shampoo that is not pH-balanced may disrupt the hair's natural pH level, leading to potential damage and dullness. Therefore, maintaining a pH-balanced shampoo is crucial for overall hair health and maintaining a shiny, strong, and vibrant appearance.
