The Wound Healing of Fractional Photothermolysis Mimics Scarless Healing with Minimal Myofibroblast Activation

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.

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.

Exosomes combined with fractional picosecond laser treatment were effective in treating androgenetic alopecia and promoting repigmentation in white hair patches. The role of exosomes in hair repigmentation, particularly in conditions like poliosis, is not well-studied.

Fatty acid metabolic signaling can activate epithelial stem cells for hair regeneration. Oleic and palmitoleic acids showed the best results, but practical application on humans remains uncertain.

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.

The user has been using minoxidil and finasteride for hair loss but is now considering microneedling due to recent hairline regression. Another user reassures that derma rolling causes only slight redness, which usually heals overnight.
