On Telogen Effluvium

    July 2025 in “ International Journal of Trichology ”
    Ralph Michel Trüeb
    TLDR Telogen effluvium is a common hair loss condition requiring careful diagnosis and treatment.
    The document provides an overview of telogen effluvium (TE), a prevalent type of hair loss marked by increased shedding during the telogen phase. TE can be acute or chronic, with chronic telogen effluvium (CTE) lasting over 6 months and sometimes associated with systemic disorders or existing as a primary condition. Headington's classification is highlighted as the most comprehensive for understanding TE's pathology. Diagnosis requires a detailed medical history, physical exam, and lab tests, with the trichogram being a key diagnostic tool. Treatment is diagnosis-specific, and while the cause of primary CTE is often unclear, it may involve multiple factors, including overlap with androgenetic alopecia. The document stresses a systematic approach to diagnosis and treatment, acknowledging the psychological effects on patients.

       4 upvotes 7 years ago
      Chronic Telogen Effluvium can be managed by avoiding inflammatory foods, exercising, staying hydrated, and using supplements like krill oil, saw palmetto, or licorice root. Minoxidil is discouraged due to its cost and potential for worsening hair loss, while castor oil is recommended to strengthen hair roots and reduce shedding.

      A 19-year-old male experienced significant hair loss, initially thought to be male pattern baldness (MPB), and used minoxidil and briefly finasteride.

      in Progress Pictures  6 upvotes 1 month ago
      The user experienced chronic telogen effluvium and mild male pattern baldness, treated with finasteride, oral minoxidil, and later switched to dutasteride, which stopped excessive hair shedding. Other treatments like low-level laser therapy, hair loss shampoos (except ketoconazole), and supplements were ineffective.
