Which method of electrolysis uses 12-14 needles to decompose the hair papilla?

1. Thermolysis Method

2. Laser Method

3. Galvanic Method

4. Blend Method

The correct answer is: Galvanic Method

The correct answer is the Galvanic Method. This method of electrolysis utilizes a series of needles, typically 12-14, which are inserted into the hair follicle. When electric current is applied, it produces a chemical reaction that decomposes the hair papilla, effectively destroying the hair growth cells at the root. In contrast to other methods, the Galvanic Method is specifically geared toward permanent hair removal through this chemical action, rather than relying solely on heat or alternating current. The needles provide a direct and targeted approach to the hair follicle, ensuring the effectiveness of the process. The other methods mentioned focus on different principles. The Thermolysis Method uses heat generated by high-frequency alternating current to destroy hair cells, while the Laser Method employs concentrated light energy to target and damage the hair follicles. The Blend Method combines the principles of both the Galvanic and Thermolysis methods, utilizing both chemical and heat for hair removal. However, none of these methods employ multiple needles in the same way as the Galvanic Method.
