Pennsylvania Esthetician State Board Practice Exam

Which hair removal method is known for being long-lasting and typically performed by a licensed professional?

1. Shaving

2. Waxing

3. Electrolysis

4. Depilatory cream

The correct answer is: Electrolysis

Electrolysis is recognized as a long-lasting hair removal method because it targets individual hair follicles for permanent reduction. This process involves using an electric current to destroy the hair growth cells, making it effective for achieving permanent hair removal. Specific training and licensure are required to perform electrolysis safely and effectively, which is why it is typically performed by licensed professionals. Other hair removal methods, while effective for temporary results, do not provide the same level of permanence. Shaving simply cuts the hair at the skin's surface and requires frequent repetition. Waxing can provide longer-lasting results than shaving, as it removes hair from the root, but the results are not permanent. Depilatory creams dissolve hair at the surface, but again, their effects are temporary. Thus, electrolysis stands out for its long-lasting results and the requirement for professional training to ensure safety and efficacy.
