The method that involves inserting a single needle into the hair follicle is the galvanic method. This technique is also known as electrolysis and is used for permanent hair removal. In the galvanic method, a low-level electric current is passed through the needle into the hair follicle, which results in a chemical reaction that destroys the hair follicle's ability to grow hair.

This precision of using a single needle allows for targeted treatment of each individual hair, making it highly effective for permanent hair removal. The process can take some time, especially in areas with dense hair, but it is considered one of the most original and effective methods of hair removal.

Other methods like thermolysis, also referred to as high-frequency electrolysis, utilize a different mechanism involving heat to destroy the hair follicle; it typically involves a probe but can heat quickly compared to the chemical reaction of the galvanic method. The multiple needle method, as the name suggests, involves using several needles simultaneously to treat multiple hair follicles at once, which differs from the targeted approach of using a single needle. Shaving, meanwhile, is simply a temporary method of hair removal that does not involve the hair follicle directly.
