De Novo Regeneration of Rete Ridges During Cetacean Skin Wound Healing

Carnosic acid in rosemary extract may enhance skin repair and promote hair follicle regeneration. It could be used alone or with verteporfin for scarless healing after dermal wounding.

A user suggests that deeper microneedling with Verteporfin injections might help regrow hair in areas with scar tissue, alongside a DHT blocker. Another user explains that hair loss might be due to reduced Wnt/β-Catenin signaling and suggests that treatments like Minoxidil, Finasteride, and microneedling could potentially reverse it.

OP injured their temple using derma rolling and tretinoin, causing peeling and potential hair follicle damage. Users suggest the injury might be permanent, possibly resulting in scar tissue where hair won't grow.

A new human trial using an FDA-approved treatment for wound healing called Verteporfin, which may potentially be able to reverse scarring and regrow hair in that area. The trial is only lasting one month so far.

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.

A human trial of verteporfin, a drug that can inhibit wound healing by scarring and promote regeneration of original tissue and hair follicles to provide an unlimited source for hair transplants; people discussed the potential of this drug and how it could be rolled out in mainstream with more doctors getting on board.
