Diffuse excessive hair shedding · Dehradun
Hair suddenly falling out in handfuls? It may be telogen effluvium—not permanent baldness.
Hair falling in handfuls · fever · stress · postpartumTelogen effluvium is a common cause of widespread, non-scarring hair shedding. It often begins two to four months after a trigger such as fever, childbirth, surgery, major stress or rapid weight loss. Many cases recover once the trigger resolves, although prolonged or recurrent shedding needs assessment to look for ongoing triggers or coexisting hair disorders.

Recognise the pattern
Common signs of telogen effluvium
These clues help distinguish one kind of hair loss from another—but images and symptoms alone cannot confirm a diagnosis.
Whole scalp
Shedding is diffuse rather than limited to a round bald patch.
Delayed trigger
Illness, childbirth or a major dietary change months earlier.
Regrowth
Short new hairs may emerge while older resting hairs shed.
Understand the cause
Why does telogen effluvium start months after illness or stress?
Hair follicles cycle between growing, resting and shedding phases. A major physiological stress can shift more follicles into the resting phase; those hairs fall out later, commonly after a two-to-four-month delay.
Triggers include significant fever, medical illness, childbirth, crash dieting, iron deficiency, certain medicines, thyroid disorders and major physical or psychological stress. Not every stressful day causes telogen effluvium, and a trigger is not always identified. It can coexist with female or male pattern hair loss.
Diagnosis first
How a dermatologist evaluates it
Clinical history and scalp examination guide whether trichoscopy, laboratory tests, microscopy or biopsy is needed. Not every patient requires all investigations.
Find the timeline
Review illness, delivery, nutritional changes, medicines and weight change in the preceding months.
Scalp and hair examination
Look for diffuse shedding with preserved follicular openings; consider a hair-pull test and trichoscopy to distinguish pattern loss.
Targeted investigations
Blood count, ferritin/iron assessment, TSH or other tests may be appropriate when history or examination suggests deficiency or systemic disease; not every patient needs a large panel.
Evidence-informed care
Treatment options — chosen for the diagnosis
Management depends on the actual condition, its severity, age, medical history and your goals. Procedures are not a replacement for treating the underlying cause.
Correct the trigger
Treat documented deficiencies, manage thyroid or other medical disease, and restore adequate protein and energy intake where needed.
Allow the cycle to recover
Acute telogen effluvium often improves over months, but hair density takes longer to recover because new hairs grow slowly. Reassurance is useful only after confirming the diagnosis.
Gentle supportive care
Normal gentle washing, avoiding tight hairstyles and minimising heat/chemical trauma can reduce additional breakage; washing does not cause the resting hairs to shed.
When extra treatment is considered
If shedding persists beyond six months, repeats or unmasks androgenetic alopecia, reassess the diagnosis. Minoxidil may be considered in selected chronic or coexisting-pattern cases; PRP/GFC is not routine first-line care for uncomplicated acute telogen effluvium.
When to seek an earlier appointment: Book an earlier review if shedding persists, you develop distinct bald patches, scalp pain, redness or scale, or symptoms such as marked fatigue or menstrual disturbance.
Realistic expectations
What follow-up usually looks like
Hair grows slowly. These are broad clinical milestones, not a guaranteed timetable for recovery or response.
2–4 months after trigger
Excessive shedding commonly becomes noticeable.
3–6 months of shedding
Many acute episodes begin improving after the trigger resolves.
6–12+ months
Fuller density may return gradually; persistent loss deserves review.
Common patient questions
Telogen Effluvium FAQs
Clear answers without unrealistic promises or one-size-fits-all treatments.
Can fever or dengue lead to hair fall?
Yes. A significant febrile illness can trigger shedding a few months later; the timing helps support telogen effluvium.
Is telogen effluvium permanent?
Usually not in acute cases. Continued triggering illness, nutritional deficiency or an overlapping diagnosis can prolong hair loss.
Why am I losing hair after childbirth?
Postpartum hormonal changes commonly trigger temporary shedding; most people gradually recover their usual density.
Should I avoid shampooing?
No. Gentle regular washing does not cause telogen effluvium; loose resting hairs would shed regardless.
Do I need biotin or iron?
Supplements are useful when a deficiency or clear indication exists—not as a universal cure for shedding.
Is telogen effluvium the same as female pattern hair loss?
No. Telogen effluvium is predominantly increased shedding, whereas female pattern hair loss causes progressive miniaturisation and reduced central density. Both may coexist.
Patient education, not a personal prescription.
