    TLDR Trichoscopy helps distinguish Lichen Planopilaris from Frontal Fibrosing Alopecia by identifying unique hair loss patterns.
    This systematic review examines the trichoscopic features of Lichen Planopilaris (LPP) and Frontal Fibrosing Alopecia (FFA), highlighting both the similarities and differences between these two conditions. The review identifies key trichoscopic features such as perifollicular scaling and perifollicular erythema, which are common in both LPP and FFA. However, it also notes distinct characteristics, such as the presence of lonely hairs and a band-like pattern of hair loss in FFA, which are not typically observed in LPP. The study emphasizes the importance of trichoscopy in differentiating between these conditions, aiding in accurate diagnosis and management.

      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.

      The conversation is about the role of testosterone in hair loss and the effectiveness of different treatments. The conclusion is that DHT is the main culprit for hair loss, and finasteride has been proven to work long-term in maintaining and regrowing hair. Testosterone may have a minor effect, but it is not the primary cause of hair loss.
