CPE Electrolysis Techniques & Procedures 2 — Questions and Answers
Question 1: In thermolysis (RF) electrolysis, what destroys the hair follicle?
- Chemical lye produced at the probe tip
- Heat generated by high-frequency alternating current (Correct answer)
- Direct galvanic current causing ion migration
- Mechanical disruption of the dermal papilla
Correct answer: Heat generated by high-frequency alternating current
Thermolysis uses high-frequency alternating current (radio frequency) to generate heat within the follicle, coagulating and destroying the germinative cells.
Question 2: Which modality is considered fastest for treating a large number of hairs per session?
- Galvanic electrolysis
- Thermolysis (RF) (Correct answer)
- Blend method
- Manual tweezers
Correct answer: Thermolysis (RF)
Thermolysis is the fastest modality because high-frequency current can destroy a follicle in a fraction of a second compared to the longer treatment times of galvanic or blend methods.
Question 3: When using the blend method, what is the primary purpose of the galvanic current component?
- To produce heat for immediate coagulation
- To generate sodium hydroxide (lye) that chemically destroys the follicle (Correct answer)
- To numb the treatment area
- To sterilize the probe before insertion
Correct answer: To generate sodium hydroxide (lye) that chemically destroys the follicle
In the blend, galvanic direct current causes electrolysis of tissue fluids to form sodium hydroxide (lye), which chemically destroys follicular tissue.
Question 4: A client's hair regrows thinner and lighter after several electrolysis sessions. This indicates:
- The wrong modality was selected
- Progressive damage to the follicle reducing its ability to produce a terminal hair (Correct answer)
- An allergic reaction to the probe metal
- Incorrect probe depth
Correct answer: Progressive damage to the follicle reducing its ability to produce a terminal hair
Gradual thinning and lightening of regrowth indicates cumulative damage to the follicle's papilla and matrix, which is a normal sign of effective treatment progression.
Question 5: What does 'epilating current' refer to in electrolysis?
- Current that removes surface skin cells
- The intensity of current needed to destroy the follicle and release the hair (Correct answer)
- Current used only during galvanic treatments
- A sterilizing electrical charge applied to instruments
Correct answer: The intensity of current needed to destroy the follicle and release the hair
Epilating current is the specific level of electrical energy applied during treatment sufficient to damage the follicle enough that the hair slides out easily without resistance.
Question 6: Which factor most directly determines the correct probe depth during an electrolysis insertion?
- Client's skin color
- The length of the hair above the skin surface
- The angle and depth of the hair follicle (Correct answer)
- The modality being used
Correct answer: The angle and depth of the hair follicle
Proper probe depth is determined by following the natural angle and depth of the follicle so the probe tip reaches the germinal matrix where hair growth originates.
Question 7: What is a 'telogen' hair and how does it affect electrolysis outcomes?
- A coarse terminal hair that requires higher intensity
- A resting-phase hair that may not be permanently destroyed in one treatment (Correct answer)
- A hair type unique to facial regions
- A hair already in the process of anagen growth
Correct answer: A resting-phase hair that may not be permanently destroyed in one treatment
Telogen hairs are in the resting phase with a shallower, club-shaped root, making them harder to epilate permanently because the germinal cells are less active and probe placement is more difficult.
