What is the pH range of an alkaline waving solution?

The pH range of an alkaline waving solution is typically between 9.0 and 9.6. Alkaline waving solutions, often used in cold wave perming techniques, are designed to penetrate the hair shaft and alter its bonds to create curls or waves. This higher pH level allows for effective hair restructuring, as the alkaline nature opens the hair cuticle, enabling the waves or curls to form properly.

In contrast, other options fall outside of the typical pH range associated with alkaline waving solutions. A pH of 7.0-8.5 is considered neutral to slightly alkaline, which is insufficient for permanent waving. A pH range of 8.5-10.0, while closer, does not specifically capture the precise pH commonly found in alkaline solutions. Lastly, a pH of 6.0-7.5 indicates a more acidic to neutral solution, which does not align with the properties needed for an effective alkaline waving solution.
