With what perm can the PH vary? (Meaning they can be either alkaline or acid)

• A. Acid perms
• B. Alkaline perms
• C. Exothermic perms
• D. Low/no Thio perms

Answer: (C)

The pH of a perm solution is determined by the formula's acidity or alkalinity. Acid perms stay in the acidic range, and alkaline perms stay in the alkaline range. Exothermic perms, however, describe the type of processing that releases heat during application. Because the exothermic category is defined by the heat-generating process rather than a fixed pH, these formulations can be made in either acidic or alkaline pH. That means the pH can vary within this category depending on the specific product. Acid perms and alkaline perms are fixed to their respective pH ranges, and low/no thio perms refer to the concentration of thioglycolate rather than to pH variability.
