During the galvanic method, lye (sodium hydroxide) is produced at which electrode?
Answer: Negative probe (cathode)
In galvanic electrolysis, direct current causes a chemical reaction at the cathode that produces sodium hydroxide (lye), which destroys the hair follicle.
Which thermolysis frequency range is typically used in professional electrology equipment in the United States?
Answer: 13.56 MHz – 27.12 MHz
US professional electrology devices operate at radio frequencies typically between 13.56 MHz and 27.12 MHz to generate the oscillating current needed for thermolysis.
What is the primary advantage of the blend method over pure galvanic electrolysis?
Answer: It works faster while retaining chemical destruction
The blend method combines thermolysis's heat with galvanic current's chemical action, speeding up lye production and reducing total treatment time compared to galvanic alone.
When treating a curved follicle, which probe insertion technique is most appropriate?
Answer: Follow the hair's natural growth angle and curve the probe tip
Curved follicles require the electrologist to angle the probe to follow the natural curve of the follicle to avoid a false insertion and ensure effective energy delivery.
Which skin condition contraindicates thermolysis treatment due to risk of heat spread?
Answer: Rosacea with telangiectasia
Rosacea with telangiectasia involves dilated superficial blood vessels that can conduct and spread thermolysis heat, increasing the risk of tissue damage and skin injury.
What does 'epilated hair' exhibiting a 'sheath attached' appearance after extraction indicate?
Answer: A successful, deep follicle treatment
When epilated hair retains a moist root sheath (anagen root sheath), it indicates the probe reached the base of the follicle and the hair was properly treated.
In the sequential blend technique, what is applied first before the thermolysis current?
Answer: A short galvanic current pulse to initiate lye production
In sequential blend, the galvanic current is applied first to begin chemical (lye) production in the follicle, then thermolysis is added to heat the lye and accelerate destruction.
