TLDR Surgeons suggested a standard system for hair transplant methods to improve communication and results.

In 1998, hair restoration surgeons proposed a standardized classification system for follicular unit transplantation (FUT) and mini-micrografting techniques to improve communication and allow for accurate comparison of procedures. The system recorded seven key elements of the surgical process and emphasized the importance of microscopic dissection for preserving follicular anatomy. The paper highlighted the benefits of large sessions in FUT for creating a natural-looking hairline and reducing the number of treatment sessions. It also stressed the significance of harvesting and dissection techniques on implant quality, recommending the use of stereo-microscopy to minimize follicle transection and a single-strip method for donor tissue to preserve follicular units. The classification aimed to standardize documentation, stimulate research, and enhance patient care, while also providing definitions for terms related to FUT and mini-micrografting.

community Verteporfin and Microneedling

in Treatments 8 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.
