    TLDR Managing frontal fibrosing alopecia and lichen planus pigmentosus is challenging due to resistant hair loss and skin discoloration.
    Frontal fibrosing alopecia (FFA) is a type of lichen planopilaris characterized by progressive hair loss on the scalp, eyebrows, and axillae. This report described a postmenopausal woman with FFA and lichen planus pigmentosus (LPP), which began with eyebrow alopecia and progressed to the frontoparietal region, accompanied by difficult-to-manage periocular and cervical hyperpigmentation. The condition was managed with systemic corticosteroids and finasteride. LPP, an uncommon variant of lichen planus, is often associated with FFA in individuals with darker skin types and presents with scarring alopecia and skin hyperpigmentation that is resistant to various treatments. This case highlighted the diagnostic and therapeutic challenges of managing scarring alopecia and perifollicular hyperpigmentation.

      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.

      community Testosterone and hair loss seeming irrelevance

      in Research/Science  81 upvotes 1 year ago
      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.
