The method that involves inserting a single needle into the hair follicle is known as thermolysis. In this process, a fine needle is introduced into the hair follicle, and then a radio frequency energy is applied to the needle. This generates heat, which effectively destroys the hair follicle, preventing the hair from growing back.

Thermolysis is commonly used in electrolysis for permanent hair removal and is appreciated for its speed compared to other methods. The focus on using a single needle enhances precision and minimizes discomfort for the client. As a result, thermolysis is a popular choice among estheticians for effective hair removal.

In contrast, other options do not specifically describe this process. The galvanic method, for example, utilizes multiple needles and a chemical reaction to destroy hair follicles, while the multiple needle method involves several needles simultaneously being inserted into the follicles. Shaving does not involve any needles at all, as it merely cuts hair at the surface level without affecting the follicle.
