    TLDR Follicular unit transplantation, a hair restoration technique using small hair grafts, was pioneered by Bob Limmer in the late 1980s and is still widely used today with minor improvements.
    In the late 1980s, Bob Limmer pioneered follicular unit transplantation, a hair restoration technique involving the use of microscopes to create small one-to-five hair grafts. These grafts, stripped of excess non-hair-bearing tissue, were transplanted into 18-gauge needle sites. This technique is still largely used today, with minor improvements. In 1995, William Rassman documented the natural growth patterns of hair, noting that hairs grow most frequently in pairs, sometimes in groups of three, and more rarely in groups of four and five. This understanding of hair groupings was crucial in designing hair restoration procedures. In 1997, Robert Bernstein and Bill Rassman coined the term "follicular unit transplantation" to describe their technique.

      The conversation discusses hair cloning trials expected to start in 2020-2021 and mentions concerns about potential delays due to the Coronavirus. Treatments like Minoxidil, finasteride, and RU58841 are referenced.

      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.

      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.
