    TLDR Surgeons make more mistakes in hair transplant procedures as they get tired or do more work.
    The study, involving 25 patients undergoing their first FUE session with over 2000 grafts, found that a surgeon's transection rate during the procedure significantly increased as the surgery progressed and with the number of follicular units harvested. Specifically, transection rates rose from 5.3/cm² to 27.7/cm² in the mid-zone, 4.4/cm² to 25.6/cm² on the right side, and 5.7/cm² to 24.2/cm² on the left side by the end of the surgery. Additionally, rates increased from 5.03 to 6.0/cm² for less than 2500 FUs, from 4.83 to 6.6/cm² for over 2500 FUs, and from 5.5 to 6.67/cm² for over 3000 FUs. The conclusion was that a higher workload for the surgeon correlates with a greater rate of hair transection during FUE procedures.

      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.

      community HRT is literal black magic. Fin 1 mg/day @ 4 years, min 2x/day @ 3 years, Estradiol 4mg/day @ 3.5 months, and Spironolactone 100mg/day @ 3.5 months (estra & spiro are medicines you should likely not take if you are a cis man)

      User shared progress on hair regrowth using Fin 1 mg/day for 4 years, Min 2x/day for 3 years, Estradiol 4mg/day, and Spironolactone 100mg/day for 3.5 months. They noted significant hairline recovery and advised against HRT for cis men due to feminizing effects.

      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.
