What pH range do acid-balanced shampoo products typically fall into?

3.0-4.0
4.5-5.5
5.5-6.5
6.5-7.5

The correct answer is: 4.5-5.5

Acid-balanced shampoo products are formulated to maintain a pH level that is close to that of healthy hair and scalp, which generally falls within the range of 4.5 to 5.5. This slightly acidic pH helps to preserve the cuticle layer of the hair, improving its integrity and overall appearance. The acidic nature of these shampoos ensures they can cleanse effectively without stripping moisture or creating damage, making them suitable for a variety of hair types, particularly those that are color-treated or damaged. Using a shampoo with a pH outside this range can lead to issues such as dryness or irritation, highlighting the importance of choosing products specifically designed to be pH-balanced for hair care.
