    TLDR Trichoscopy is a reliable method for diagnosing hair and scalp disorders quickly and non-invasively.
    From 2015 to 2019, a case-control study involving 605 patients was conducted to assess the effectiveness of trichoscopy in diagnosing hair and scalp disorders. The study found that trichoscopy, a non-invasive diagnostic technique, was effective in identifying features of different types of alopecia and scalp disorders. For instance, in diffuse alopecia areata, common findings included black dots, yellow dots, broken hair, and vellus hairs. In androgenetic alopecia, hair diameter variability of ≥20% was the most common finding. The study also identified 35 distinctive trichoscopic features significant in diagnosing localized and diffuse alopecias. The study concluded that trichoscopy is a reliable tool for quick and non-invasive assessment of the scalp, which can guide therapy and management.

      How diffuse unpatterned alopecia (DUPA) is not an invitation to self-diagnose oneself with aggressive AGA and that seeking a specialized dermatologist may help people experiencing hair loss. Treatment options discussed include topical clobetasol propionate, oral minoxidil, and discontinuing finasteride.

      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.

      A person with hair loss since COVID-19 is considering treatments like finasteride and minoxidil but is hesitant due to potential side effects. Suggestions include visiting a dermatologist, using a ketoconazole shampoo, and considering that post-COVID hair loss might be an autoimmune response.
