    TLDR Hair transplants can lead to hair loss from lichen planopilaris, and patients should be tested and wait two years before the procedure.
    The document describes two cases where patients experienced hair loss due to lichen planopilaris (LPP) after undergoing hair transplants, highlighting the rarity of such occurrences. The first patient had hair loss in the recipient and donor areas six years post-transplant, while the second patient showed partial hair loss with active disease two years after the procedure. Histopathological examination confirmed LPP, and one patient was treated with intralesional triamcinolone, which stabilized the lesions. The study underscores the necessity of a scalp biopsy to confirm LPP inactivity before transplantation and recommends a waiting period of at least two years of disease inactivity before proceeding with a transplant. It also advises informing patients about the potential for reduced graft integration due to the systemic and autoimmune nature of LPP.

      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.

      A young female diagnosed with Lichen planopilaris (LPP) experienced years of misdiagnosis and ineffective treatments, including a hair transplant and other procedures. She is considering litigation due to the misdiagnosis and has learned that LPP is chronic, hair loss can be stopped with ongoing medication, but lost hair cannot regrow.

      community Testosterone and hair loss seeming irrelevance

      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.
