Effect of Inhibiting Prolactin Secretion on Secondary Hair Follicle Development in Cashmere Goats

Prolactin may contribute to hair loss, but targeting its receptor won't cure androgenetic alopecia. ABS-201 could be a useful alternative or adjuvant therapy, similar to JAK inhibitors, but not more effective than HMI-115.

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, 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.

A new drug targeting prolactin is being discussed for hair regrowth, but skepticism remains as many still rely on minoxidil and finasteride. Concerns include the drug's effectiveness compared to existing treatments and whether it works for those already using 5AR inhibitors.

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.

PP405 is a promising molecule that may reactivate dormant hair follicles, potentially offering a new treatment for hair loss. It is in phase 2 trials, with possible availability between 2027 and 2030.
