    TLDR Trichoscopic patterns often overlap in scalp disorders, so dermatologists need to stay updated.
    The study conducted at Sree Balaji Medical College and Hospital involved 100 patients with newly diagnosed scalp dermatoses, focusing on identifying trichoscopic patterns to differentiate between various scalp disorders. The research found that 67% of the patients presented with alopecia, with 83.5% having non-scarring alopecia and 16.4% having scarring alopecia. Alopecia areata was the most common condition, with 20 cases showing specific trichoscopic signs like exclamation mark hairs. In androgenetic alopecia cases, consistent patterns such as anisotrichosis and an increased vellus-to-terminal hair ratio were observed. The study concluded that while some trichoscopic signs are specific, many patterns overlap across different conditions, highlighting the importance for dermatologists to stay informed about the latest trichoscopic findings.

      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.
