Investigation of the Role and Mechanism of Pigment Epithelium-Derived Factor (PEDF) in Androgenetic Alopecia

PP405, a topical treatment, shows promise for hair growth by activating inactive follicles, with 66% of participants experiencing positive results. The treatment is well-tolerated and may proceed directly to Phase 3 trials, offering a potential alternative to minoxidil and finasteride.

Pelage is developing a topical hair follicle stem cell therapy, PP405, for non-scarring alopecias like androgenetic alopecia, with Phase III trials planned and a potential market launch by 2027. The treatment may not require continuous use after initial regrowth.

PP405 shows promise for hair regrowth, with new hairs observed in 66% of patients in just 27 days. The discussion also mentions Minoxidil, finasteride, and RU58841 as potential treatments.

Hair follicle stem cells remain in bald individuals, but progenitor cells do not, raising questions about hair regrowth claims by Pelage. PP405 is discussed as a potential treatment, with skepticism about its effectiveness compared to existing treatments like Minoxidil and Finasteride.

Pilose antler extracts may promote hair growth in androgenetic alopecia by activating hair follicle stem cells through the AKT and Wnt pathways. However, results in mice may not directly apply to humans due to differences in genetic and biochemical conditions.

PP405 shows promise in regenerating hair by activating dormant follicles. Other treatments like VDPHL01 and Breezula are also advancing, providing new hope for hair loss solutions.
