What is a common effect of using galvanic electrolysis?

Using galvanic electrolysis involves the application of a direct electrical current to hair follicles, which causes a chemical reaction. This process generates sodium hydroxide at the hair follicle, effectively destroying the hair and preventing regrowth. The correct choice states that a common effect of using galvanic electrolysis is the neutralization of sodium hydroxide. This is significant because the sodium hydroxide generated is crucial in the hair removal process; if it is neutralized, it means that the electrolysis is successfully targeting and managing the byproduct associated with hair destruction.

In the context of electrolysis, the aim is to achieve permanent hair removal by ensuring that the hair follicle is treated effectively, which involves managing the byproducts generated during the process. This makes the neutralization of sodium hydroxide a key part of understanding galvanic electrolysis and its mechanism.
