Toward Understanding Scarless Skin Wound Healing and Pathological Scarring

Peptides like TB500, KPV, GHK-CU, and BPC-157 are overhyped for hair growth with limited proven effectiveness in humans. Combining peptides with delivery methods like iontophoresis and sonophoresis shows promise, but many claims remain unproven.

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.

Microneedling for hair restoration involves daily use of a 0.3 mm device and weekly use of a 0.5 mm device. Combining microneedling with Minoxidil can enhance hair growth.

Oleic acid and microneedling are being explored for hair regrowth, but results are mixed. Addressing DHT and fibrosis is crucial, with treatments like finasteride, minoxidil, and scalp massage also discussed.

Topical Metformin shows potential for regenerating hair follicles and minimizing scarring in hair transplant donor areas, similar to Verteporfin but without its side effects. The discussion suggests considering Metformin for post-hair transplant care, though more human trials are needed.
