Best Peptides for Thinning Hair & Density: Evidence Ranked
An evidence-graded ranking of the peptides marketed for hair thinning, density, and shedding — separating the modest human topical data from the mechanistic and mouse-only hype.
Androgenetic Alopecia
Androgenetic Alopecia is a recurring topic in our peptide coverage. This hub collects every article tagged Androgenetic Alopecia, newest first, each evidence-graded and tied to real, verifiable sources.
Best Peptides for Hair Loss: 2026 Evidence Review
An evidence-graded ranking of the peptides marketed for androgenetic alopecia — zinc-thymulin, biotinoyl tripeptide-1/Procapil, GHK-Cu copper peptide, and PTD-DBM — separating the small human data from mouse work, blends, and marketing.
Peptides for Hair Growth: Evidence, Grades & Safety
A clinical, evidence-first ranking of the peptides marketed for hair regrowth — zinc-thymulin, copper peptides, biotinoyl tripeptide-1 (Procapil) and PTD-DBM — graded honestly, with human versus preclinical evidence kept strictly separate.
Zinc-Thymulin: Evidence, Mechanism, Dosing & Legal Status
A clinical monograph on zinc-thymulin — the zinc-dependent thymic nonapeptide marketed as a topical hair-growth peptide. One small open-label human trial, solid zinc-biomarker biology, no RCT, and an unsettled 2026 legal status.
PTD-DBM: Evidence, Mechanism, Dosing & Legal Status
A clinical monograph on PTD-DBM — the CXXC5-Dishevelled disrupting peptide engineered to reactivate Wnt/β-catenin signaling for hair regrowth. Strong target biology, mouse-only efficacy, and no human trials.
Biotinoyl Tripeptide-1 (Biotinyl-GHK) for Hair: Evidence & Safety
A clinical monograph on Biotinoyl Tripeptide-1 — the biotinylated GHK matrikine peptide behind Procapil. Modest, consistent hair-density benefits in combination formulations, but no isolated-molecule human trial.
