Telogen Effluvium: Causes, Symptoms, Treatment, and Prevention

What Is Telogen Effluvium?

Telogen Effluvium (TE) is a temporary hair shedding condition caused by a disruption in the hair growth cycle. Hair follicles prematurely enter the resting (telogen) phase, resulting in diffuse hair loss.

Causes of Telogen Effluvium

  • Physical or emotional stress
  • Illness, surgery, or trauma
  • Nutritional deficiencies (iron, zinc, protein)
  • Hormonal changes (postpartum, menopause, thyroid disorders)
  • Medications (anticoagulants, retinoids, chemotherapy)

Common Triggers:

  • Sudden weight loss or crash diets
  • Severe infections
  • High fever or prolonged illness
  • Emotional stress

Symptoms

  • Diffuse thinning across the scalp
  • Increased hair shedding during washing or brushing
  • Temporary thinning that occurs 2–3 months after a trigger
  • No bald patches, but noticeable volume loss

Diagnosis

  • Review of recent medical history or triggers
  • Physical examination of scalp and hair
  • Hair pull test
  • Blood tests to rule out nutritional or hormonal deficiencies

Treatment Options

Lifestyle and Nutritional Support:

  • Address underlying triggers (stress, illness, nutrition)
  • Improve diet with iron, zinc, and protein
  • Avoid harsh hair care practices

Medications:

  • Minoxidil for promoting regrowth in prolonged TE
  • Treat underlying hormonal or thyroid disorders

Prognosis:

  • Hair usually regrows within 3–6 months after trigger removal
  • Chronic TE may persist longer and require ongoing management
