EC Staging & Prognostic Factors 3 — Questions and Answers
Question 1: Which of the following best describes the 'catagen' phase in terms of electrolysis prognosis?
- Ideal phase — highest treatment success rate
- Transitional phase — moderate success, papilla beginning to detach (Correct answer)
- Resting phase — poorest success rate
- Growth phase — deepest follicle, easiest insertion
Correct answer: Transitional phase — moderate success, papilla beginning to detach
During catagen, the follicle is transitioning and the dermal papilla is partially detached, making treatment moderately effective but less so than anagen.
Question 2: When assessing a client for electrolysis, a Fitzpatrick skin type VI client requires special staging consideration because:
- Higher current is needed due to increased melanin
- Risk of post-inflammatory hyperpigmentation and keloid formation is elevated (Correct answer)
- Treatment is contraindicated for all Fitzpatrick VI clients
- Less current is needed because dark skin conducts electricity better
Correct answer: Risk of post-inflammatory hyperpigmentation and keloid formation is elevated
Fitzpatrick VI skin has elevated melanin and a higher predisposition to post-inflammatory hyperpigmentation and keloid scarring, requiring conservative current settings and careful staging.
Question 3: A client's intake form reveals they are taking isotretinoin (Accutane). How should this affect the treatment staging plan?
- Proceed normally; isotretinoin does not affect electrolysis
- Delay treatment until 6–12 months after discontinuation due to impaired healing (Correct answer)
- Increase treatment frequency to compensate for drug effects
- Use only galvanic current to avoid skin sensitivity
Correct answer: Delay treatment until 6–12 months after discontinuation due to impaired healing
Isotretinoin impairs skin healing and increases sensitivity to tissue trauma, requiring a 6–12 month waiting period after discontinuation before electrolysis.
Question 4: Which statement about curved or distorted follicles and their prognostic significance is correct?
- Curved follicles are easier to treat due to natural probe guidance
- Curved follicles increase the risk of improper probe insertion and skin damage (Correct answer)
- Follicle curvature has no impact on treatment success
- Curved follicles require less current to treat
Correct answer: Curved follicles increase the risk of improper probe insertion and skin damage
Curved or distorted follicles make accurate probe placement difficult, increasing the risk of off-target energy delivery and reduced effectiveness.
Question 5: When staging a treatment plan for a large area such as the full back, which scheduling approach is most appropriate?
- Complete the entire area in one extended session
- Work systematically in sections with adequate healing time between sessions (Correct answer)
- Treat only the densest zones and ignore peripheral hair
- Schedule once per month regardless of area size
Correct answer: Work systematically in sections with adequate healing time between sessions
Sectional treatment with appropriate healing intervals prevents over-treatment of tissue, reduces adverse reactions, and allows accurate assessment of regrowth.
Question 6: A client who previously had laser hair removal is now seeking electrolysis on residual hair. What prognostic consideration applies?
- Laser pre-treatment has no effect on electrolysis outcomes
- Remaining hairs may have distorted follicles, making probe insertion more challenging (Correct answer)
- Laser always eliminates the need for electrolysis entirely
- Previous laser treatment speeds up electrolysis results significantly
Correct answer: Remaining hairs may have distorted follicles, making probe insertion more challenging
Laser can alter follicle shape and depth in survivors, creating distorted angles that complicate accurate probe placement during electrolysis.
Question 7: The presence of ingrown hairs in the treatment area is a prognostic factor because:
- Ingrown hairs are easier to treat as the follicle is more accessible
- They indicate distorted follicle angles that complicate probe insertion (Correct answer)
- Ingrown hairs resolve spontaneously and need not be factored into planning
- They require higher frequency thermolysis settings only
Correct answer: They indicate distorted follicle angles that complicate probe insertion
Ingrown hairs reflect abnormal follicle angles, which create a challenging insertion path and increase the risk of skin damage during electrolysis.
