A Peptide Derivative with Known Anti-Wrinkle Properties Identified as Potent Dipeptidylpeptidase-4 Inhibitor

A peptide from Japanese water chestnut fruit may help with hair loss by suppressing DHT's effect on hair follicle cell death, potentially serving as a finasteride alternative. The treatment's effectiveness and safety in humans remain uncertain.

The conversation is about the use of peptide therapies for hair loss, specifically GHK-CU, ZN-Thymulin, and PTD-DBM. The user is seeking feedback on the effectiveness of these treatments from those who have tried them.

A quercetin-encapsulated and polydopamine-integrated nanosystem (PDA@QLipo) shows promise for treating androgenetic alopecia by reshaping the perifollicular microenvironment, outperforming minoxidil in hair regeneration. The nanosystem promotes cell proliferation, hair follicle renewal, and recovery by scavenging reactive oxygen species and enhancing neovascularity.

PP405's phase 2a trial results were presented, focusing on safety and pharmacokinetics, with a future meeting planned to share the full dataset. The trial includes a randomized controlled portion and an open-label extension, with no indication of phase 2B completion.

A peptide-based hair loss treatment, PP405, reportedly increased hair density by 62% in 90 days, but these claims are unverified and met with skepticism. Users compared PP405 to Minoxidil and Finasteride, expressing doubts about its effectiveness without more evidence.

The conversation discusses interest in peptides for hair loss, specifically mentioning ahkCU and ghkCU. A user is considering adding ghkCU to their treatment regimen.
