    TLDR Dr. Shoji Okuda's early hair transplantation techniques were rediscovered after being overlooked due to World War II.
    In 1939, Japanese doctor Shoji Okuda published a series of papers on hair transplantation techniques, which were similar to those later described by Dr. Norman Orentreich in 1959. Okuda's work, which was largely forgotten due to the onset of World War II, included hair transplantation for cicatricial alopecia, as well as pubic hair, eyebrow, and mustache reconstruction using custom-made punches with a diameter of 1.5–5mm. He found that the optimal survival rate of transplanted hair was achieved with punches of 2.5–4mm in diameter. Okuda also discovered that scalp hair could survive and continue to grow at any site, and that all cases of hetero-hair-transplantation were unsuccessful. His work was rediscovered 30 years later by German surgeon Professor H.C. Friederich. Okuda's original papers were translated into English and made available to scholars in 2003.

      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.

      Han Bio plans to start clinical trials for a new hair multiplication technology this year, which could significantly reduce the cost and time of hair transplantation. The technology uses a single hair strand to cultivate enough cells for 30,000 hair strands.

      community Verteporfin and Microneedling

      in Treatments 3 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.
