    TLDR Hair follicle damage happens during hair transplants and can impact success; better surgical methods are needed.
    In 2017, a study analyzed 4,200 hair grafts from 42 patients to assess minor follicle trauma during Follicular Unit Extraction (FUE) for hair transplantation. Researchers found an average transection rate (TR) of 7.40% with a ×5.5 magnifying loupe and 6.34% with a ×60 microscope. They observed that paring and hair bulb injuries were more noticeable under microscopic examination. The study concluded that minor damages, such as to the dermal papilla and hair bulb, occur during FUE and could affect the success of the transplant. It highlighted the need for further research to improve surgical techniques and optimize patient outcomes, noting that the level of skill and technique variations can influence the rate of trauma to the follicles.

      community Verteporfin and Microneedling

      in Treatments 5 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.
