Hair Loss Quiz
Questions: 16 · 10 minutes
1. Which situation provides the clearest reason to seek prompt professional evaluation rather than relying only on cosmetic hair care?
A few split ends after delaying a haircut
A long-standing hair whorl that has not changed
Rapid hair loss accompanied by scalp pain, redness, scaling, or pus
Mild frizz during humid weather
2. After frequent bleaching and high-heat styling, a person sees many short hairs of uneven length but little hair coming out from the root. What is the most likely process?
Diffuse shedding from synchronized follicle cycling
An autoimmune attack producing smooth bald patches
Inherited miniaturization limited to the crown
Hair-shaft breakage caused by physical or chemical damage
3. A person notices slowly increasing recession at the temples and thinning at the crown over several years, with similar changes in close relatives. Which pattern best fits this description?
Alopecia areata causing sharply defined patches
Telogen effluvium caused by a recent body-wide trigger
Androgenetic alopecia, also called pattern hair loss
Hair-shaft breakage caused by grooming damage
4. Approximately how many scalp hairs per day is commonly cited as a typical shedding range, although individual patterns vary?
About 1-5 hairs
About 50-100 hairs
About 300-500 hairs
More than 1,000 hairs
5. A friend recommends high-dose biotin to everyone with thinning hair. Which response best reflects current general medical knowledge?
It is not a universal treatment; deficiency is uncommon, and high doses can interfere with some lab tests
Biotin is harmless at any dose because the body removes all excess
High-dose biotin reliably treats all common forms of hair loss
Biotin works only when thinning is caused by tight hairstyles
6. Which finding is most characteristic of alopecia areata?
Gradual thinning limited mainly to the temples and crown
Diffuse shedding following childbirth, illness, or major stress
Frayed ends and snapped hairs after repeated heat styling
One or more relatively smooth, clearly defined patches of hair loss
7. A child has an enlarging scaly scalp patch with broken hairs. Which concern warrants clinical assessment?
Normal adult pattern hair loss beginning early
Ordinary graying of the hair shaft
Temporary shedding caused solely by shampoo frequency
A fungal scalp infection such as tinea capitis
8. A person who regularly wears very tight braids develops tenderness and thinning along the hairline. Which type of hair loss should be considered?
Postpartum telogen effluvium
Traction alopecia
Alopecia areata
Classic crown-predominant pattern hair loss
9. A few months after giving birth, someone notices substantial diffuse shedding without smooth bald patches or scalp inflammation. Which explanation is most plausible?
Postpartum hormonal changes can trigger temporary telogen effluvium
The pattern confirms a contagious scalp infection
The shedding must be caused by a new shampoo
Childbirth always causes permanent follicle destruction
10. During which phase of the hair cycle does a scalp hair actively grow?
Telogen
Exogen
Anagen
Catagen
11. Three months after a high fever, someone develops increased shedding from all over the scalp. Which explanation is most consistent with that timing and pattern?
The fever permanently destroyed most hair follicles
The illness may have triggered telogen effluvium, which can appear after a delay
The shedding proves an inherited pattern of hair loss
The fever caused immediate scarring alopecia that remained hidden
12. A person sees improvement while using topical minoxidil and asks what may happen if treatment is stopped. Which statement is most accurate?
Hair maintained or regrown with treatment may gradually be lost after stopping
A short course permanently resets the hair-growth cycle
Stopping usually converts pattern hair loss into alopecia areata
All shedding after stopping indicates irreversible scarring
13. Why might a clinician consider thyroid or iron-status testing when a person's history and symptoms suggest those possibilities?
These tests can determine the cause of every case of hair loss
Both conditions cause only sharply defined smooth patches
Thyroid dysfunction and iron deficiency can contribute to diffuse shedding in some people
Normal results prove that no hair disorder is present
14. Before ordering tests, a clinician asks about medications, diet, recent illness, family history, and styling practices, then examines the scalp. Why is this approach useful?
Different causes can look similar, so history and examination help guide appropriate testing
The history alone can confirm every cause without an examination
Every type of hair loss requires the same laboratory panel
Laboratory tests are never useful when evaluating hair loss
15. Someone considering a hair transplant believes the procedure will stop all future pattern hair loss. Which correction is most accurate?
Transplanted hair always falls out permanently within a few weeks
A transplant redistributes follicles but does not necessarily stop progression in non-transplanted hair
A transplant changes the inherited tendency in every scalp follicle
Transplants are designed primarily to treat fungal scalp infections
16. Someone has an expanding area of hair loss with burning, a shiny-looking scalp, and fewer visible follicle openings. What is the most appropriate response?
Switch shampoos and reassess after a full year
Take a high-dose supplement before seeking advice
Assume it is ordinary seasonal shedding
Arrange prompt medical evaluation for possible scarring hair loss
