Targeted Overexpression of the Angiogenesis Inhibitor Thrombospondin-1 in the Epidermis of Transgenic Mice Prevents Ultraviolet-B-Induced Angiogenesis and Cutaneous Photo-Damage

The user does not respond well to minoxidil and is seeking an alternative to Tretinoin to upregulate sulfurtransferase activity for hair loss treatment. No specific alternative treatments were mentioned.

Tazarotene shows potential as a standalone treatment for hair regrowth by stimulating new hair follicle formation and promoting angiogenesis, similar to microneedling effects. It can be used topically without minoxidil, but users should start with a low concentration to avoid irritation.

Verteporfin followed by retinoic acid improves wound regeneration in mini-pigs. Retinoic acid does not significantly enhance regeneration in rabbits.

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.

Verteporfin, combined with microneedling, shows promise for hair regrowth by allowing hair follicles to grow in wounds, but it's expensive and painful. Pai-1 inhibitors may also help prevent hair loss by degrading fibrosis, and some users continue using minoxidil alongside these treatments.

Hair loss may be linked to the TRPS1 gene and protein, not just DHT. Amplifica's AMP-303 targets mesenchymal stem cells and shows promise in treating hair loss, unlike Pelage's PP405.
