dermis
3. Q: What is the arrector pili muscle? ANSWER A small muscle
attached to the hair follicle that causes the hair to stand up
4. Q: What are the three phases of hair growth? ANSWER Anagen
(growth phase), catagen (transition phase), and telogen (resting phase)
5. Q: Which phase of hair growth is ideal for electrolysis treatment?
ANSWER Anagen phase, when the hair is actively growing and
connected to the papilla

follicle that contains blood vessels and nerves, nourishing the hair
7. Q: What is the hair bulb? ANSWER The enlarged base of the hair
root that surrounds the papilla
8. Q: What are the two types of sweat glands? ANSWER Eccrine
(produce watery sweat) and apocrine (produce thicker, odorous sweat)
9. Q: What is sebum? ANSWER An oily substance produced by
sebaceous glands that lubricates skin and hair
10.Q: Where are sebaceous glands located? ANSWER Attached to hair
follicles in the dermis
11.Q: What is the stratum corneum? ANSWER The outermost layer of
the epidermis consisting of dead, keratinized cells
12.Q: What cells produce melanin? ANSWER Melanocytes
,13.Q: What is the function of melanin? ANSWER To protect the skin
from UV radiation by absorbing light
14.Q: What is the hair shaft? ANSWER The visible part of the hair above
the skin surface
15.Q: What is the hair root? ANSWER The part of the hair below the
skin surface, embedded in the follicle
16.Q: What is the medulla of the hair? ANSWER The innermost layer of
the hair shaft, often absent in fine hair
17.Q: What is the cortex of the hair? ANSWER The middle layer of the
hair shaft that contains melanin and determines hair strength
18.Q: What is the cuticle of the hair? ANSWER The outermost
protective layer of overlapping scales on the hair shaft
19.Q: What is hirsutism? ANSWER Excessive hair growth in women in a
male pattern distribution
20.Q: What is hypertrichosis? ANSWER Excessive hair growth
anywhere on the body, not necessarily in a male pattern
21.Q: What is the hair follicle angle? ANSWER The direction in which
the hair grows beneath the skin surface
22.Q: What percentage of body hair is typically in the anagen phase?
ANSWER Approximately 85-90% on the scalp; varies by body area
23.Q: How long does the anagen phase last on the face? ANSWER
Approximately 4-12 months
24.Q: What is the function of the dermis? ANSWER Provides structural
support, contains blood vessels, nerves, and appendages
25.Q: What type of tissue makes up the dermis? ANSWER Connective
tissue containing collagen and elastin fibers
26.Q: What is keratinization? ANSWER The process by which cells
produce keratin and become hardened
27.Q: What is the germinal matrix? ANSWER The area of active cell
division at the base of the hair follicle
28.Q: What are vellus hairs? ANSWER Fine, soft, lightly pigmented
hairs found on most of the body
, 29.Q: What are terminal hairs? ANSWER Coarse, dark, long hairs found
on the scalp, face, and body
30.Q: What is lanugo hair? ANSWER Fine, unpigmented hair found on
fetuses and newborns
31.Q: What nerve supplies sensation to the face? ANSWER The
trigeminal nerve (5th cranial nerve)
32.Q: What are the three branches of the trigeminal nerve? ANSWER
Ophthalmic, maxillary, and mandibular
33.Q: What is the function of blood vessels in the skin? ANSWER
Supply nutrients, remove waste, regulate temperature
34.Q: What is collagen? ANSWER A protein that provides strength and
structure to the skin
35.Q: What is elastin? ANSWER A protein that allows skin to stretch and
return to its original shape
36.Q: What causes hair to turn gray? ANSWER Decreased melanin
production by melanocytes
37.Q: What is the infundibulum? ANSWER The upper portion of the
hair follicle extending from the skin surface to the sebaceous gland
38.Q: What is the isthmus? ANSWER The middle portion of the hair
follicle from the sebaceous gland to the arrector pili muscle
39.Q: What is the bulge area of the follicle? ANSWER The area where
the arrector pili muscle attaches, containing stem cells
40.Q: What determines hair texture? ANSWER The shape of the hair
follicle and cross-sectional shape of the hair shaft
41.Q: What causes ingrown hairs? ANSWER Hair grows back into the
skin instead of growing outward, often due to curved follicles
42.Q: What is folliculitis? ANSWER Inflammation or infection of the hair
follicle
43.Q: What is pseudofolliculitis barbae? ANSWER Chronic
inflammation caused by ingrown hairs, common in curly-haired
individuals
44.Q: How deep are facial hair follicles typically located? ANSWER 2-4
millimeters below the skin surface
