What is Telogen Effluvium?

Telogen Effluvium is a common yet often misunderstood cause of temporary hair loss. It occurs when a significant number of hair follicles enter the resting phase (telogen) of the hair cycle prematurely, usually triggered by physical or emotional stress. About three months later, these hairs are shed, leading to noticeable thinning.

In most cases, this condition is temporary and resolves when the body recovers from the underlying trigger. However, when hair shedding continues for more than six months, it is referred to as Chronic Telogen Effluvium. In this chronic form, hair thinning is evident, but the follicles remain intact.

Acute vs. Chronic Telogen Effluvium

Feature	Acute Telogen Effluvium	Chronic Telogen Effluvium
Duration	Short-term condition	Lasts longer than 6 months
Cause	Triggered by a specific stressor	Hair appears thinner, but follicles remain
Hair Regrowth	Usually occurs within 6 months	Often requires professional assessment to identify ongoing triggers

Common Triggers of Telogen Effluvium

The onset is usually linked to a stressor or change that disrupts the natural hair cycle. Common causes include:

Psychological & Physical Stress

Emotional events such as bereavement, divorce, or intense work pressure can push follicles into the resting phase. Physical stress, such as surgery, can have the same effect. In both cases, shedding often begins around 3 months later and may resolve once the stressor is managed.

Medication-Induced Hair Loss

Some prescription drugs can trigger Telogen Effluvium. These include certain blood pressure medications, antidepressants, and treatments for other chronic conditions. If a medication is suspected, professional evaluation is essential before making any changes.

Pregnancy & Childbirth:

During pregnancy, higher hormone levels extend the hair growth phase, giving fuller, thicker hair. After childbirth, the sudden drop in oestrogen can trigger significant shedding (often 2–4 months later). Most cases resolve within 6 months, but repeated pregnancies may contribute to progressive thinning.

Contraceptive Changes:

Starting or stopping oral contraceptives can affect hormone balance, leading to Telogen Effluvium. Some pills contain male hormones (androgens) that may also trigger pattern-like hair loss.
