Sodium hydroxide is the chemical agent that effectively destroys hair during galvanic electrolysis. In this process, the electric current interacts with sodium hydroxide, producing a reaction that generates lye. The lye penetrates the hair follicle, effectively destroying the hair root and preventing future growth. This specific chemical reaction is fundamental to the efficacy of galvanic electrolysis, making it a widely used method in hair removal treatments.

The other options do not serve the same purpose in this context. Hydrochloric acid is an acid that may have different applications but is not used for hair destruction in this technique. Calcium carbonate is primarily a calcium salt and has no role in the hair removal process. Potassium chloride may be useful for various physiological processes but lacks the necessary chemical properties to disrupt hair follicles in electrolysis. Understanding these distinctions is critical for those working in the field of electrolysis, as it highlights the specific application and importance of sodium hydroxide in the galvanic method.
