    TLDR Trichoscopy helps tell apart other hair loss conditions from common hair loss.
    The document discusses the use of trichoscopy, a non-invasive diagnostic tool, for identifying conditions that mimic androgenetic alopecia (AGA), a common type of hair loss. It details several conditions that can be mistaken for AGA, such as Telogen effluvium, Lichen planopilaris, Fibrosing alopecia in pattern distribution, Central centrifugal cicatricial alopecia, Hairline maturation, Frontal fibrosing alopecia, Traction alopecia, Trichotillomania, and Alopecia Areata. Each condition has specific trichoscopic features that can differentiate them from AGA. The document also highlights the need to evaluate pseudotrichoscopic signs, often connected with hair dyeing and the use of various hair products, which can lead to misdiagnosis. It emphasizes the importance of a thorough history in conjunction with trichoscopy for accurate diagnosis and monitoring the progression of AGA and the effectiveness of treatments.

      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.
