Neutralizer has a pH that ranges from _______ to _______. (depending on the type of neutralizer)

• A. 1 to 4
• B. 2.5 to 7
• C. 3 to 6
• D. 4 to 9

Answer: (B)

Neutralizers are formulated to stop the chemical action of the waving solution and to help rebuild the hair’s bonds while re-establishing a stable, balanced pH. Because different neutralizers are designed for different systems, their acidity level can vary: some are more acidic to quickly neutralize and close the cuticle, while others are formulated closer to neutral to suit specific processing needs. This flexibility means the pH range for neutralizers generally spans from about 2.5 up to 7. In other words, depending on the product type, a neutralizer may be quite acidic or near neutral, which is why 2.5 to 7 is the typical range.
