In the context of blend modality, thermolysis refers to the application of heat generated from radiofrequency or alternating current during the hair removal process. When thermolysis is applied to lye, which is chemically known as sodium hydroxide, it increases the overall temperature and enhances its activity level.

As the lye heats up, its caustic properties become more pronounced, resulting in a more effective hair removal process. The heightened temperature increases the dissociation of the lye into its component ions, which in turn increases its potency as a depilatory agent. This leads to a greater physiological reaction that effectively damages the hair follicle, thereby improving the efficacy of the treatment.

The other options do not accurately reflect the chemical and physical changes that occur with thermolysis in the blend modality. The misconception that lye might become less caustic or neutralizes completely does not take into account the key role of heat in enhancing the reactivity of the sodium hydroxide. Additionally, the idea that it forms a gel-like substance does not apply, as the nature of the chemical does not change into a gel through this process; rather, it remains a caustic substance with amplified effects.
