What is the primary purpose of the intensity control on an electrolysis unit?
Answer: To adjust the amplitude of current delivered to the follicle
The intensity control adjusts the milliamperage (amplitude) of the current delivered, which determines the destructive energy at the follicle.
A thermolysis unit emitting an audible alarm during treatment most likely indicates:
Answer: A circuit fault, overheating, or impedance error requiring immediate shutdown
Alarms on modern thermolysis units typically signal equipment faults such as circuit errors, overheating, or abnormal impedance that require the operator to stop and investigate.
Which needle gauge is most commonly used for fine facial hair in electrology?
Answer: F6 (fine)
F6 is a fine-gauge probe appropriate for thin, fine facial hairs where minimal tissue displacement is needed.
When performing blend electrolysis, the RF current is used to:
Answer: Heat the lye produced by galvanic current, enhancing its destructive action
In blend modality, RF (thermolysis) current heats the sodium hydroxide (lye) produced by galvanic current, making it more caustic and speeding follicle destruction.
An electrologist notices the galvanic current reading fluctuates erratically during treatment. The most likely cause is:
Answer: A loose or corroded connection in the circuit, including the indifferent electrode lead
Erratic galvanic current readings most often result from poor electrical connections — corroded leads, a loose indifferent electrode, or a faulty probe holder.
The indifferent (inactive) electrode used in galvanic electrolysis serves to:
Answer: Complete the electrical circuit through the client's body
The indifferent electrode completes the DC galvanic circuit, allowing current to flow from the probe through tissue and back to the machine.
Which of the following best describes a 'two-needle' or 'double-needle' technique?
Answer: Treating two adjacent follicles simultaneously with separate circuits
The two-needle (or multi-needle) galvanic technique uses multiple probes in separate follicles connected to the same galvanic circuit to treat several hairs simultaneously.
