Telogen Effluvium, Diagnosis and Management: A Narrative Review

Telogen Effluvium (TE) is a prevalent form of hair loss characterized by diffuse shedding, which can be acute or chronic. The review highlights that TE is often triggered by factors such as hormonal changes, stress, or medications, and typically presents about 3 months after the triggering event. Diagnosis involves tools like trichoscopy and the hair pull test, and it's crucial to identify any underlying causes, such as thyroid issues or nutritional deficiencies, to effectively manage the condition. While Acute TE (ATE) usually resolves on its own, Chronic TE (CTE) may require more extensive evaluation and differentiation from other hair loss disorders. Treatment includes patient education on the natural progression of TE, addressing the root cause, and potentially using supplements or promising treatments like topical minoxidil and stemoxydine. Psychological support may be beneficial for stress-related TE, and hair regrowth can take up to 18 months.
