    TLDR Yellow dots were the most common sign of alopecia areata found using trichoscopy.
    In 2020, a study was conducted on 122 patients with clinically diagnosed alopecia areata to determine the trichoscopic findings in the adult population. Trichoscopy, a non-invasive modality, was used for rapid detection of alopecia areata, predicting the cause of the disease, and reducing unnecessary biopsies. The most common trichoscopic findings were yellow dots, observed in 108 (88.5%) patients, followed by short vellus hair in 66 (54.1%) patients, short regrowing hair in 58 (47.5%) patients, exclamation mark hair in 56 (45.9%) patients, black dots in 44 (36.1%) patients, and broken hair in 34 (27.9%) patients.

      Diffuse hair loss and scalp biopsies

      community Diffuse hair loss and scalp biopsies

      in Research  692 upvotes 3 months ago
      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.

      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.

      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.
