    TLDR Plucked hair follicles grow faster than conventional ones, making them a potentially better option for hair transplants.
    In a study conducted in 2016, researchers compared the growth rates of conventional human micrografts and plucked hair follicles in an in vitro model to assess the potential use of plucked follicles in hair transplantation procedures. The study involved 100 conventional one-hair micrografts (control group) and 80 plucked hair follicles (experimental group) obtained from 14 healthy male patients. The results showed a statistically significant difference in the growth rate between the two groups, with the plucked hair follicles showing a higher growth rate (mean 10-day shaft growth rate = 0.36mm) compared to the conventional one-hair micrografts (mean 10-day shaft growth rate = 0.30mm). The researchers concluded that plucked hair follicles could be a useful and less invasive option in hair transplantation surgery. However, they noted that this was an in vitro study and further in vivo studies are needed to confirm these findings.

      community Han Bio Planning Hair Multiplication Trial This Year?

      in Technology  6 upvotes 4 years ago
      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 1 year 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.
