EC Electrolysis Principles and Techniques 2 — Questions and Answers
Question 1: What is the primary purpose of the epilator's intensity control during electrolysis treatment?
- To regulate the amount of current delivered to the follicle (Correct answer)
- To control the speed of needle insertion
- To adjust the temperature of the treatment room
- To set the timer between insertions
Correct answer: To regulate the amount of current delivered to the follicle
Intensity control regulates the milliamperage of current delivered, which determines the degree of tissue destruction at the follicle.
Question 2: Which tissue structure must be destroyed to achieve permanent hair removal with electrolysis?
- The hair shaft
- The dermal papilla (Correct answer)
- The sebaceous gland
- The arrector pili muscle
Correct answer: The dermal papilla
The dermal papilla, which supplies nutrients to the hair follicle, must be destroyed to prevent regrowth.
Question 3: In thermolysis (shortwave), what happens to tissue water molecules during treatment?
- They are frozen solid
- They vibrate rapidly producing heat (Correct answer)
- They are chemically converted to lye
- They migrate toward the needle tip
Correct answer: They vibrate rapidly producing heat
High-frequency alternating current causes water molecules to vibrate at millions of cycles per second, generating heat that coagulates follicle tissue.
Question 4: A client has coarse, deeply rooted hairs on the chin. Which treatment modification is most appropriate?
- Use lower intensity and shorter timing
- Use higher intensity or longer timing (Correct answer)
- Switch to a smaller probe gauge
- Increase treatment frequency to daily sessions
Correct answer: Use higher intensity or longer timing
Coarse, deeply rooted hairs require more energy (higher intensity or longer timing) to ensure the germinative cells are fully destroyed.
Question 5: What does the term 'multiple needle method' refer to in galvanic electrolysis?
- Using several probes simultaneously on multiple follicles (Correct answer)
- Inserting one needle multiple times in the same follicle
- Using needles of varying gauges in the same session
- Alternating between galvanic and thermolysis modes
Correct answer: Using several probes simultaneously on multiple follicles
The multiple needle method places several needles in multiple follicles simultaneously, allowing lye to form in each over a period of minutes.
Question 6: Which probe size is generally preferred for treating fine, shallow vellus hairs?
- Size 2 (thickest)
- Size 4
- Size 6
- Size 8 (finest) (Correct answer)
Correct answer: Size 8 (finest)
Fine vellus hairs have narrow follicles requiring the finest probes (size 8) to avoid damage to surrounding tissue.
Question 7: What is 'galvanic current' in the context of electrolysis?
- Alternating current at radio frequencies
- Direct current that produces a chemical reaction (Correct answer)
- Pulsed current used in blend treatments
- Current measured in volts rather than milliamps
Correct answer: Direct current that produces a chemical reaction
Galvanic current is unidirectional (direct) current that decomposes sodium chloride and water into sodium hydroxide (lye), destroying follicle tissue chemically.
