FPRS hair restoration

Question 1

What are the layers of the scalp?

Answer 1

Skin, loose connective tissue, galea or epicranial aponeurosis, loose areolar tissue, periosteum

Question 2

What are the five main arteries that supply blood

to the scalp?

Answer 2

● Supratrochlear
● Supraorbital
● Superficial temporal
● Occipital
● Posterior auricular arteries

Question 3

What makes up the hair bulb?

Answer 3

Papilla combined with surrounding epidermal cells

Question 4

What is the function of the hair bulb?

Answer 4

Site of hair shaft formation

Question 5

What is a follicular unit?

Answer 5

A group of one to four hairs with an accompanying
neurovascular plexus, arrector pili muscle, and sebaceous
glands

Question 6

What are the phases of hair growth?

Answer 6

● Anagen
● Catagen
● Telogen

Question 7

What is the primary growth phase of the hair growth cycle?

Answer 7

Anagen phase

Question 8

What are some infectious and inflammatory

causes of alopecia?

Answer 8

Dermatophytes, demodex folliculorum, foliculitis, secondary

syphilis, seborrheic dermatitis, psoriasis, pityriasis amiantacea

Question 9

What is the most common cause of male baldness?

Answer 9

Androgenic alopecia

Question 10

What hormone plays the most significant role in

androgenic alopecia?

Answer 10

Dihydrotestosterone

Question 11

What is the most widely used classification system

for hair loss?

Answer 11

Norwood classification (stages I through VII)

Question 12

What classification system is most commonly used

for grading female androgenic alopecia?

Answer 12

Ludwig classification (grades 1 through 3)

Question 13

What is the mechanism of finasteride in the

treatment of hair loss?

Answer 13

5α-Reductase inhibitor; blocks the conversion of serum

testosterone into dihydrotestosterone

Question 14

What is the most common topical medication

prescribed for alopecia?

Answer 14

Minoxidil. Treatment results in a lengthening of the anagen

phase and an increase in the blood supply to the follicle.

Question 15

How long should balding patients use minoxidil

before they can expect to see noticeable results?

Answer 15

4 to 6 months

Question 16

What hair qualities yield better results with hair

replacement surgery?

Answer 16

Hair color that matches skin color, coarse texture, high

density, curly

Question 17

What is follicular unit extraction?

Answer 17

The process by which follicular units are harvested
individually as opposed to the strip method in which a strip
of scalp is removed and then cut into individual follicular
units

Question 18

What are the advantages of follicular unit extraction?

Answer 18

Can be harvested from multiple different areas on the scalp.
A long postoperative scar is avoided compared with the
strip method of harvesting.

Question 19

What is the difference between follicular unit micrografts and minigrafts?

Answer 19

Micrografting involves transplantation of one or two hair
follicles per unit used predominantly at the hair line,
whereas minigrafts are three or four hair follicles used to fill
in bulk areas.

Question 20

After transplantation, what phase of hair growth will transplanted hair enter?

Answer 20

Telogen phase. Patients should be told to expect that the transplanted hairs will fall out, with regrowth occurring by 3
to 4 months.

Question 21

Where is the donor strip of hair typically taken for hair transplantation?

Answer 21

Occipital region near the inion

Question 22

What are the primary advantages of scalp flaps over hair transplantation?

Answer 22

Scalp flaps maintain the blood supply to hair follicles, thus
preventing them from entering the telogen phase; hair
continues to grow immediately after the procedure; hair
density is maximized with instantaneous results.

Question 23

What is the Juri flap?

Answer 23

The Juri flap is an axial scalp flap based on the superficial
temporal artery that allows for the entire frontal hairline to
be covered with a single flap.

Question 24

In the context of hair restoration treatments, what

is scalp reduction?

Answer 24

Scalp reduction is a technique that reduces the surface area of the balding scalp using serial excisions. Areas of balding are excised and closed primarily or with various local flaps.

Question 25

Review the role of tissue expanders in hair restoration.

Answer 25

Tissue expanders do not increase the number of follicles but increase the distance between follicles to cover a larger surface area. Usually, they can be expanded by a factor of 2 without noticeable thinning.
