    TLDR Trichoscopy is a useful tool for diagnosing hair and scalp issues, but doctors must be careful to avoid mistakes.
    The document from 2018 discusses trichoscopy as a noninvasive diagnostic tool for hair and scalp disorders, useful for identifying early scarring alopecias and selecting biopsy sites. It points out the necessity of examining different scalp areas and using various magnifications, while also considering unique features in pigmented scalps. The article advises clinicians to be cautious of pitfalls like scalp staining and environmental deposits that can lead to misdiagnosis. It categorizes trichoscopic features and emphasizes the importance of correlating these with the patient's history and clinical picture. The document also notes that trichoscopy is especially beneficial for children, but warns of misinterpretation due to artifacts. It underscores the need for dermatologists to keep abreast of advancements in trichoscopy to avoid diagnostic errors.

      Diffuse hair loss and scalp biopsies

      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.
