    TLDR Antimalarial agents are effective for LPP, and intralesional steroids are effective for FFA.
    This systematic review updated the treatment options for Lichen planopilaris (LPP) and Frontal Fibrosing Alopecia (FFA) by analyzing 38 studies published between March 2012 and June 2017. The review found that antimalarial agents and pioglitazone improved LPP in 73% and 71% of patients, respectively. Topical steroids and Tacrolimus/Pimecrolimus showed improvement and stabilization in about one-third and 50% of LPP cases, respectively. For FFA, antimalarial agents improved 68% of cases, intralesional steroids 83%, finasteride 100%, and dutasteride 95%. The review concluded that antimalarial agents were more effective than steroids for LPP, while intralesional steroids were more effective than antimalarial agents for FFA. However, the low quality and heterogeneity of the studies limited the ability to establish a definitive treatment protocol.

      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.
