What is the pH range of a pH balanced shampoo?

• A. 3.0-4.0
• B. 4.5-5.5
• C. 5.5-6.5
• D. 6.5-7.5

Answer: (B)

A pH balanced shampoo is formulated to have a pH level that closely matches the natural pH of healthy hair and scalp, which typically falls within the range of 4.5 to 5.5. This acidic range helps to maintain the hair's cuticle structure and prevent damage while promoting overall scalp health. Shampoos that are too alkaline can cause the hair cuticles to swell and raise, leading to potential frizz, dryness, and damage. On the other hand, shampoos with a pH lower than this range can excessively acidify the hair, potentially leading to a brittle texture. Therefore, the 4.5 to 5.5 range ensures that the shampoo effectively cleanses while preserving the integrity of the hair and maintaining scalp health.
