The Usefulness of Trichoscopy in Diagnosing Fibrosing Alopecia in Pattern Distribution

    TLDR Trichoscopy is crucial for accurately diagnosing fibrosing alopecia in pattern distribution.
    This report emphasizes the importance of trichoscopy in diagnosing fibrosing alopecia in pattern distribution (FAPD), particularly in differentiating it from female pattern hair loss (FPHL). In a case study of a 49-year-old postmenopausal woman with hair thinning and scalp symptoms, trichoscopy revealed specific features such as areas lacking follicular orifices and hair shaft thickness heterogeneity, leading to a diagnosis of FAPD. Treatment with hydroxychloroquine and finasteride halted disease progression and alleviated symptoms over a 1-year follow-up. Accurate diagnosis is crucial due to the distinct trichoscopic features and differing treatment approaches between FAPD and FPHL.

      Scalp biopsies are crucial for diagnosing hair loss conditions like Diffuse Unpatterned Alopecia (DUPA) and retrograde hair loss, as treatments like finasteride and dutasteride may not be effective if other conditions are present. Combining PPAR-GAMMA agonists with retinoids could improve treatments for conditions like Lichen Planopilaris.

      The conversation is about the role of testosterone in hair loss and the effectiveness of different treatments. The conclusion is that DHT is the main culprit for hair loss, and finasteride has been proven to work long-term in maintaining and regrowing hair. Testosterone may have a minor effect, but it is not the primary cause of hair loss.

      The user experienced hair loss since 2019 and tried finasteride, dutasteride, RU58841, and ketoconazole shampoo without success. A scalp biopsy showed scarring and inflammation from folliculitis, indicating chronic inflammation was affecting treatment effectiveness.

      The user experienced hair loss despite using Fin and Min for 12 years and switched to Dutasteride, RU58841, and Keto scalp serum, but shedding and itch persist. They are considering increasing Dutasteride to 2.5mg and questioning the necessity of a scalp biopsy, with mixed opinions on its usefulness.

      The user has been using finasteride, minoxidil, and nizoral for hair loss but hasn't seen regrowth, only maintenance. They are considering switching to dutasteride, which is believed to be more effective, but are concerned about potential side effects.
