Which term describes the method that uses both direct and alternating currents?

• A. Probes
• B. Point Effect
• C. Galvanic Electrolysis
• D. Blend Method

Answer: (D)

The technique that uses both direct and alternating currents is the blend method. It combines galvanic current, which creates a caustic chemical inside the follicle to destroy the hair papilla, with high-frequency alternating current that rapidly heats and coagulates tissue. This dual action amplifies destruction and can be especially effective for coarser hair. The other options don’t describe a method that uses both currents: galvanic electrolysis relies on direct current alone, thermolysis relies on alternating current alone, and probes are tools rather than a method, while point effect refers to a different concept.
