Anti-Keratin Monoclonal Antibodies for Identifying Animal Hair Fibers

PP405 is a potential hair loss treatment that inhibits mitochondrial pyruvate carriers, increasing lactate dehydrogenase activity and stimulating hair follicle stem cells. In a phase 1 trial, 31% of participants showed over 20% hair density increase with PP405 treatment.

Pelage Pharmaceuticals' PP405 aims to treat hair loss by reactivating dormant hair follicle stem cells, showing promising results in early trials. The company plans to present their findings at the American Academy of Dermatology Annual Meeting in 2026.

MCL-1 protein may help maintain hair follicles in the growth phase and prevent miniaturization. There is interest in experimental treatments like exosomes, peptides, or stem cell serums to upregulate MCL-1 for hair loss, especially for those not using minoxidil or finasteride.

A user applied the 8T3 product for hair loss, targeting LPP and AGA, and plans to update on its effectiveness. The product uses a saline buffered phosphate vehicle, suitable for those intolerant to ethanolic vehicles.

ABS-201 may block prolactin receptors in hair, potentially reducing androgen receptors and affecting hair loss. It could also aid collagen synthesis and stem cell pathways, similar to GHK-Cu.

Pelage Pharmaceuticals raised $120M for their hair loss treatment, PP405, showing strong investor confidence despite limited data. There is skepticism about its efficacy and long-term effects compared to treatments like GT20029.
