The blend method for permanent hair removal uses which two electrical modalities?

• A. Direct current only
• B. Alternating current only
• C. High frequency and galvanic current
• D. Radiofrequency and ultrasound

Answer: (C)

The blend method relies on combining two modalities: galvanic current and high-frequency current. Galvanic current is direct current that within the follicle creates a chemical reaction, producing sodium hydroxide that destroys the follicle tissue. High-frequency current delivers energy quickly, heating the tissue (thermolysis) to coagulate and destroy the follicle. Using both at once leverages the chemical destruction from the alkaline reaction and the rapid heating from the high-frequency energy, making the hair removal more efficient and often faster than using either modality alone. This differs from galvanic alone, which relies on chemical cauterization, or thermolysis alone, which relies on heating without the chemical effect. The option involving radiofrequency and ultrasound isn’t the standard blend for permanent hair removal.
