The galvanic or multiple-needle electrolysis technique is characterized by using which arrangement?

• A. Multiple needles inserted into follicles
• B. A single needle only
• C. No needles, only surface heating
• D. Laser fiber delivery

Answer: (A)

Direct current in galvanic electrolysis creates a chemical change inside the follicle, effectively destroying the hair papilla. To produce this effect across a treated area, multiple needles are inserted into follicles, and current flows between them to generate an alkaline reaction (sodium hydroxide) within each follicle. This multi-needle arrangement allows simultaneous treatment of many follicles and relies on chemical destruction rather than just heating. Using only a single needle would limit the area and the chemical action, while no needles would mean no current, and laser delivery is a different modality that uses light, not electrical current.
