Telogen Effluvium — What Is This Temporary Type of Hair Loss?

What happens in the follicle

A higher-than-usual number of hairs shift into the resting phase (telogen) at once — the effect shows up a few months later as increased, diffuse shedding, not concentrated in one spot.

What most often triggers it

• Severe physical or psychological stress.
• Hormonal changes, e.g. after childbirth.
• High fever, surgical procedures, a sudden change in diet.

Is it permanent

Usually not — in most cases it resolves on its own once the triggering factor is gone. If it drags on or is very pronounced, that's a signal to see a dermatologist, not to keep waiting.

What to discuss during a consultation

An article about “Telogen Effluvium — What Is This Temporary Type of Hair Loss?” can help organise the subject, but the cause of a hair or scalp problem needs an individual assessment. Sudden or worsening hair loss, pain, itching or changes to the scalp should be discussed with a doctor or dermatologist.

Bring information about when the symptoms started, your health conditions, medicines and recent health changes. This helps clarify whether further tests are appropriate and what next steps may make sense.
