Key Takeaways
Telogen effluvium is a temporary form of hair loss triggered by physical or emotional stress
Most cases resolve within 3-6 months without long-term consequences
Up to 30% of hair can shift into the resting phase during an episode
Multiple factors can contribute to this type of hair loss
Hair loss can be a distressing experience, but understanding telogen effluvium can help reduce anxiety and provide clarity about this common condition. When your body experiences significant stress, it can respond in unexpected ways, and hair loss is one of the most visible manifestations of internal disruption.
Telogen effluvium (TE) is a reversible hair loss condition where more hair follicles than normal enter the resting (telogen) phase simultaneously. This leads to increased hair shedding, typically noticed months after a stressful event. Unlike permanent hair loss conditions, telogen effluvium represents a temporary disruption in the natural hair growth cycle.
The Hair Growth Cycle Explained
The human hair growth cycle consists of three primary phases: anagen (growth), catagen (transition), and telogen (resting). During normal conditions, approximately 10-15% of your hair remains in the telogen phase, with about 50-100 hairs naturally shedding daily. In telogen effluvium, this balance becomes significantly disrupted.
When stress impacts the body, it can cause up to 30% of hair follicles to prematurely enter the resting phase. This means instead of the usual 50-100 hairs shed daily, you might experience more significant hair loss of 300 or more hairs per day.
Types of Telogen Effluvium
Acute Telogen Effluvium
Acute telogen effluvium typically lasts less than six months and resolves once the underlying stressor is addressed. Common triggers include:
Major surgical procedures
Significant weight loss
High fever
Childbirth
Psychological stress
Chronic Telogen Effluvium
Chronic cases persist beyond six months and may require more comprehensive investigation. These can be associated with ongoing medical conditions, persistent nutritional deficiencies, or prolonged stress states.
Common Causes of Hair Loss
Several factors can trigger telogen effluvium, including:
Severe physical stress
Nutritional deficiencies
Hormonal changes
Medications
Emotional trauma

Diagnosis and Treatment
Diagnosing telogen effluvium involves a comprehensive medical history and potential blood tests to identify underlying causes. Treatment typically focuses on addressing the root stressor and supporting overall health.
