In galvanic electrolysis, which agent is primarily responsible for destroying hair?

In galvanic electrolysis, the primary agent responsible for destroying hair is sodium hydroxide. When an electric current is passed through a conductive solution containing sodium hydroxide, it generates a chemical reaction that breaks down the hair's protein structure. This is achieved through the process of electrolysis, where sodium hydroxide acts as a depilatory agent by creating a local alkaline environment that effectively dissolves hair follicles and impairs their ability to regrow.

The other substances listed do not play a significant role in the hair removal process within this specific context. Hydrogen peroxide is commonly used as a bleaching agent and does not have the same effect as sodium hydroxide in terms of destroying hair. Calcium chloride might be involved in other chemical processes but is not utilized in galvanic electrolysis for hair removal. Acetic acid, while a weak acid, does not provide the necessary alkaline environment needed for effective hair destruction in this context.
