A pH balanced shampoo is balanced to the pH of?

1. Hair and skin

2. Water

3. The environment

4. Soap

The correct answer is: Hair and skin

A pH balanced shampoo is specifically formulated to match the pH level found on the surface of hair and skin. It helps maintain the natural acidity of the scalp and prevents it from being too alkaline or too acidic. Option B, water, generally has a neutral pH level of 7 and using a shampoo that is not pH balanced can disrupt the natural pH level of the scalp. Option C, the environment, is too broad of an answer as different parts of the environment have different pH levels. Option D, soap, typically has a higher pH level and can be too harsh for the scalp, causing it to become dry or irritated. Therefore, option A, hair and skin, is the correct answer as a pH balanced shampoo is specifically designed to match and maintain the pH level of the scalp.
