Question: 1 / 400

What is the purpose of acid-balanced shampoos?

To enhance hair color

To maintain the hair's natural pH balance

Acid-balanced shampoos are specifically formulated to maintain the hair's natural pH balance. Human hair typically has a pH range of about 4.5 to 5.5, which is slightly acidic. This acidity helps to keep the cuticle layer of the hair closed and intact, reducing frizz and protecting the hair from damage. When hair is exposed to harsher alkaline products, the cuticle can lift, leading to increased porosity and damage over time. By using an acid-balanced shampoo, you help to preserve this natural acidity, resulting in healthier, shinier, and more manageable hair.

The other options do not accurately reflect the primary purpose of acid-balanced shampoos. While enhancing hair color, removing dandruff, or providing moisture are important effects of certain products, they do not align with the core function of acid-balanced shampoos, which is to maintain the hair's pH balance.
