ELECTROLYSIS IBEC+LASER STATE BOARD PRACTICE TEST 2025/26 QUESTIONS
WITH COMPLETE SOLUTIONS!!
Question 1
In which stage of the hair growth cycle is the follicle at its deepest point and most heavily
saturated with moisture, making it the ideal time for electrolysis treatment?
A) Catagen
B) Telogen
C) Anagen
D) Exogen
E) Kenogen
Correct Answer: C) Anagen
Rationale: Anagen is the active growth phase of the hair follicle. During this stage, the hair
is attached to the dermal papilla, and the follicle is at its maximum depth and moisture
content. Because water is a conductor for electricity and a requirement for the chemical
production of lye in galvanic electrolysis, treatments are most effective during this phase.
Question 2
What is the primary chemical produced at the negative electrode (cathode) during a Galvanic
electrolysis treatment?
A) Hydrochloric Acid
B) Sodium Hydroxide (Lye)
C) Hydrogen Peroxide
D) Ozone
E) Carbon Dioxide
Correct Answer: B) Sodium Hydroxide (Lye)
Rationale: Galvanic electrolysis uses direct current (DC) to cause a chemical decomposition
of the salt and water found in the tissue. At the negative pole (the probe), sodium hydroxide
(lye), hydrogen gas, and chlorine gas are produced. The lye is the caustic agent that
destroys the germinative cells of the hair follicle.
Question 3
Which of the following describes the "Short-Wave" or High-Frequency modality in electrolysis?
A) It uses direct current to create a chemical reaction.
B) It uses alternating current to create heat through molecular friction.
C) It uses a combination of lye and heat.
D) It relies on the movement of ions to the positive pole.
E) It is the slowest method of hair removal.
Correct Answer: B) It uses alternating current to create heat through molecular friction.
Rationale: Thermolysis, also known as short-wave or high-frequency, utilizes an alternating
current (AC). When this high-frequency current enters the follicle, it causes the water
, 2
molecules in the surrounding tissue to vibrate rapidly. This friction generates "electro-
desiccation" or "electro-coagulation" heat, which destroys the tissue.
Question 4
What is the purpose of the "Blend" method in electrolysis?
A) To use only high frequency to speed up the process.
B) To produce lye and then use heat to make the lye more corrosive and faster-acting.
C) To eliminate the need for a grounded return electrode.
D) To treat only the surface of the skin.
E) To reduce the amount of lye produced to zero.
Correct Answer: B) To produce lye and then use heat to make the lye more corrosive and
faster-acting.
Rationale: The Blend method combines Galvanic (DC) and Thermolysis (AC) currents. The
Galvanic current produces lye, while the Thermolysis current heats that lye. Heated lye is
significantly more caustic and moves through the tissue more easily, allowing for a more
thorough destruction of the follicle in less time than Galvanic alone.
Question 5
In the Fitzpatrick Skin Typing scale, a person who always burns, never tans, and has very fair
skin and blue eyes would be classified as:
A) Type I
B) Type II
C) Type III
D) Type IV
E) Type V
Correct Answer: A) Type I
Rationale: The Fitzpatrick scale measures the skin's response to UV radiation. Type I is the
most sensitive, characterized by very fair skin, often with red or blonde hair, and a total
inability to tan. These individuals are at the highest risk for skin damage and require the
most cautious settings in laser treatments.
Question 6
Which layer of the skin contains the blood vessels, nerves, and hair follicles?
A) Stratum Corneum
B) Stratum Lucidum
C) Epidermis
D) Dermis
E) Hypodermis
, 3
Correct Answer: D) Dermis
Rationale: The dermis is the "true skin" located beneath the epidermis. It is composed of
connective tissue and contains all the essential structures that sustain the hair, including the
dermal papilla, sebaceous glands, and the arrector pili muscle. Electrolysis and laser
treatments must target this layer to be permanent.
Question 7
The "Point Effect" in thermolysis refers to the fact that:
A) Lye is strongest at the tip of the probe.
B) Heat is concentrated at the very tip of the needle.
C) High frequency only works on coarse hair.
D) The probe must be pointed at the sebaceous gland.
E) The patient must point their toe during treatment.
Correct Answer: B) Heat is concentrated at the very tip of the needle.
Rationale: The Point Effect is a phenomenon where the high-frequency current density is
greatest at the tip of the electrode (the probe). This allows the electrologist to target the
base of the follicle (the papilla) precisely, minimizing damage to the upper layers of the
skin.
Question 8
Which of the following is a mandatory requirement for an autoclave to achieve true sterilization?
A) 100 degrees Fahrenheit for 60 minutes
B) 250 degrees Fahrenheit at 15 psi for 15-20 minutes
C) 350 degrees Fahrenheit for 2 hours
D) Washing with soap and water followed by alcohol
E) Soaking in glutaraldehyde for 10 minutes
Correct Answer: B) 250 degrees Fahrenheit at 15 psi for 15-20 minutes
Rationale: Sterilization is the destruction of all microbial life, including spores. An autoclave
uses saturated steam under pressure. To be effective, it must reach at least 250°F (121°C) at
a pressure of 15 pounds per square inch (psi) for a minimum of 15-20 minutes to penetrate
all surfaces of the instruments.
Question 9
What is the correct term for the "transition" phase of hair growth where the hair detaches from
the papilla?
A) Anagen
B) Telogen
C) Catagen
D) Exogen
E) Lanugo
, 4
Correct Answer: C) Catagen
Rationale: Catagen is the shortest phase of the hair cycle. During this time, the lower part of
the hair follicle disintegrates and the hair bulb detaches from the dermal papilla, moving
upward. Treating hair in this stage is less effective than in Anagen because the target (the
papilla) is no longer connected to the hair shaft.
Question 10
In Laser Hair Removal, the term "LASER" is an acronym for:
A) Light Applied by Special Energy Radiation
B) Longwave Amplification by Saturated Electronic Rays
C) Light Amplification by Stimulated Emission of Radiation
D) Leveling Atoms by Systematic Electronic Rotation
E) Light Absorption by Selective Energy Release
Correct Answer: C) Light Amplification by Stimulated Emission of Radiation
Rationale: This acronym describes the physics of how a laser works: an energy source
stimulates atoms to emit photons of a specific wavelength, which are then amplified and
focused into a coherent beam of light.
Question 11
Which hair structure is responsible for provide the "new" cells that form the hair shaft?
A) Cortex
B) Medulla
C) Cuticle
D) Germinative cells (Matrix)
E) Arrector pili
Correct Answer: D) Germinative cells (Matrix)
Rationale: The matrix is the part of the hair bulb where cell division (mitosis) occurs. These
germinative cells are the targets of electrolysis; if they are not completely destroyed, the
follicle can regenerate a new hair.
Question 12
Which type of current is used in Galvanic electrolysis?
A) Alternating Current (AC)
B) Direct Current (DC)
C) Pulsed Light
D) Radio Frequency
E) Static Electricity
Correct Answer: B) Direct Current (DC)
Rationale: Galvanic electrolysis requires a constant flow of electricity in one direction
