TLDR New punch technologies have improved hair transplant results over time.

The study analyzed data from 1415 male patients who underwent hair transplantation by the Follicular Unit Extraction (FUE) method at a single clinic from 2011 to 2020. The aim was to assess the impact of punch technology development on the number of total grafts and follicular units (FUs) with multiple hairs. The results indicated that the total grafts and multi-hair FUs increased over the years due to advancements in punch devices. The serrated punch significantly increased total graft numbers, while the trumpet punch significantly increased the number of 3FU grafts. The study also found that total and III FU grafts increased with alcohol intake, but decreased with age and the number of sessions. The conclusion was that hair yield has improved with new punch technologies, making the FUE method the preferred choice for hair transplantation.

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.
