    TLDR Expert surgeons have a lower rate of hidden damage to hair during hair transplant procedures than beginners.
    In 2016, a study involving 20 patients examined hidden transection rates during Follicular Unit Extraction (FUE), a type of hair transplantation. The study compared the performance of an expert and a beginner surgeon, revealing that while visible transection rates were similar, the hidden transection rate was significantly higher for the beginner at 8% compared to 2% for the expert. The findings highlighted the importance of considering both visible and hidden transections to accurately assess the real transection rate in FUE. The study suggested that excessive or deep punch insertion could cause hidden transections and noted the need for further research to understand the effects of hidden transection on hair regrowth and the influence of different variables. However, the study was limited by its small size and the high transection rate from the test punches used.

      community Verteporfin and Microneedling

      in Treatments 6 months ago
      Clinical studies by Dr. Barghouthi and Dr. Bloxham indicate that Verteporfin, when used with FUE and FUT hair transplantation methods, shows promise in hair follicle regeneration and minimal scarring due to its ability to inhibit Yes-associated protein (YAP). Microneedling at depths of 3-3.5mm, combined with Verteporfin, could potentially reactivate dormant follicles, although the optimal dosage and application method are still under investigation. Concerns remain about the DHT sensitivity of regenerated follicles, highlighting the need for further research to optimize trauma levels and Verteporfin concentrations to achieve effective and scar-free hair regeneration.

      The conversation is about the progress of verteporfin in hair loss trials, with users expressing curiosity about its effectiveness and updates. Specific treatments mentioned include FUE (Follicular Unit Extraction) combined with verteporfin, with one reported case of donor area regrowth after a year, and three patients being monitored post-treatment by Dr. Bloxham with monthly updates on YouTube.
