DOMAIN 1: Anatomy, Physiology & Dermatology of the Hair (15 Questions)
Sub-Topic: Three Phases of Hair Growth Cycle & Epilation Technique (4 Questions)
Question 1 (Multiple-Choice)
During which phase of the hair growth cycle is the hair most effectively treated with electrolysis
because the dermal papilla is fully attached to the blood supply and the follicle contains
maximum moisture and salt?
A. Catagen
B. Telogen
C. Anagen
D. Exogen
Correct Answer: C [CORRECT]
Rationale: The Anagen phase is the active growth stage where the hair bulb is deep within the
subcutaneous tissue and contains a rich blood supply to the dermal papilla. During this phase,
the follicle has abundant water and salt (electrolytes), making it the optimal target for both
galvanic and thermolysis modalities. The hair shaft is firmly attached to the papilla, enabling
effective destruction of germinative cells. Treatment during Anagen provides the highest
probability of permanent follicle destruction.
Question 2 (Multiple-Choice)
A client presents for treatment with a hair that has a dry, shriveled bulb and is easily extracted
with minimal resistance. The follicle appears one-third the size of a typical active follicle. Which
growth phase is this hair in, and what is the recommended treatment approach?
A. Anagen—treat immediately with standard intensity
B. Catagen—treat with increased intensity and deeper insertion
C. Telogen—defer treatment; the hair will shed naturally and a new anagen hair will emerge
D. Exogen—treat with blend modality to catch the emerging new hair
,Correct Answer: C [CORRECT]
Rationale: The Telogen phase is the resting stage where the hair follicle has shrunk to
approximately one-third the size of an anagen follicle. The dermal papilla has atrophied and
separated from the matrix, the hair bulb is dry and keratinized (club hair), and the hair is loosely
anchored. Electrolysis during telogen is ineffective because: (1) the papilla is not accessible for
destruction, (2) there is insufficient moisture and salt for galvanic action, and (3) the hair will
shed naturally before the next anagen cycle begins. The correct approach is to defer treatment
and schedule the client to catch the new anagen hair when it emerges.
Question 3 (Multiple-Choice)
During the Catagen phase, what specific anatomical change occurs that makes electrolysis less
effective?
A. The dermal papilla enlarges and produces additional stem cells
B. The papilla separates from the matrix of the hair bulb, and melanin production ceases
C. The arrector pili muscle contracts and pushes the hair deeper into the follicle
D. The sebaceous gland doubles in size to lubricate the shedding hair
Correct Answer: B [CORRECT]
Rationale: The Catagen phase is a brief transitional period (approximately 2–3 weeks) during
which the hair follicle undergoes involution. The specific changes include: (1) the dermal papilla
separates from the matrix of the hair bulb, (2) epithelial cell apoptosis occurs in the follicle bulb,
(3) melanin production in the germinative zone ceases, and (4) the follicle shrinks upward
toward the bulge region. Because the papilla is no longer connected to the matrix, destruction
of germinative cells is incomplete. While early catagen hairs may still be treatable if the needle
reaches the root depth, the success rate is significantly lower than during anagen.
Question 4 (True/False)
Because all hair follicles on the body operate independently and are in different phases of the
growth cycle, multiple electrolysis sessions over 12–18 months are required to treat all hairs
during their anagen phase.
A. True
B. False
Correct Answer: A [CORRECT]
, Rationale: True. Each follicle operates on its own independent biological clock. At any given
time, only a percentage of follicles are in anagen (approximately 85–90% on scalp; lower
percentages on body areas). The asynchronous cycling means that a single treatment session
will only catch the subset of hairs currently in anagen. Hairs in catagen or telogen will not be
effectively treated and will produce new anagen hairs later. Therefore, a series of treatments
spaced according to the hair growth cycle (typically 4–6 weeks apart for body hair, 1–2 weeks
for facial hair) is necessary to achieve complete clearance. This is a fundamental principle of
permanent hair removal.

Questions)
Question 5 (Multiple-Choice)
Which structure in the hair follicle contains stem cells capable of completely regenerating the
follicle and is the target for permanent destruction during electrolysis?
A. The sebaceous gland
B. The dermal papilla
C. The bulge region
D. The arrector pili muscle
Correct Answer: C [CORRECT]
Rationale: The bulge region is located in the outer root sheath, approximately at the level of the
sebaceous gland duct insertion. It contains pluripotent stem cells that can regenerate the entire
follicle, including the inner root sheath, hair shaft, and dermal papilla. For electrolysis to be truly
permanent, the treatment must destroy not only the dermal papilla but also the stem cells in
the bulge region. If the bulge stem cells survive, they can regenerate a new papilla and produce
a new hair. The blend modality is particularly effective for reaching and destroying both the
papilla and the bulge region due to its combined chemical and thermal action.
Question 6 (Multiple-Choice)
The dermal papilla is located at the base of the hair follicle and serves what specific function?
A. It produces sebum to lubricate the hair shaft
B. It is a vascularized structure that nourishes the hair bulb and regulates hair growth
C. It contracts to cause piloerection (goosebumps)
D. It produces melanin pigment for the hair shaft
