  • This table compares the primary peptides studied for hair follicle activation, detailing their mechanisms, application routes, and research evidence specific to telogen effluvium recovery.
  • GHK-Cu (Copper Peptide)
  • Stimulates VEGF, TGF-β, collagen synthesis; delivers copper to lysyl oxidase for ECM remodeling
  • Topical (0.05–0.1% formulations)
  • J Dermatol Sci 2015: 22% increase in hair shaft elongation in human scalp explants
  • Requires penetration-enhancing vehicle; effects limited to application site
  • Best-supported option for localized follicle stimulation; works through direct dermal papilla signaling
  • Thymosin Beta-4 (Tβ4)
  • Regulates actin polymerization, promotes keratinocyte migration from bulge to dermal papilla
  • Subcutaneous injection (5–10 mg twice weekly in animal models)
  • UPenn research: accelerated anagen re-entry in telogen-phase follicles in knockout/rescue mouse models
  • No postpartum-specific human trials; dosing extrapolated from wound healing studies
  • Mechanistically sound but lacks postpartum clinical validation; promising for research
  • MK 677 (Ibutamoren)
  • Growth hormone secretagogue; elevates IGF-1 to prolong anagen duration via cyclin D1 upregulation
  • Oral (10–25 mg daily)
  • Growth Horm IGF Res 2012: IGF-1 elevation correlated with increased hair density in aging adults
  • Systemic effects (appetite increase, mild insulin resistance); not follicle-specific
  • Practical for systemic IGF-1 support but broader metabolic impact requires monitoring
  • BPC-157
  • Promotes angiogenesis, modulates growth factor expression; unclear direct follicle pathway
  • Subcutaneous or oral
  • Limited direct hair follicle research; primarily studied for tendon/ligament repair
  • Mechanism for follicle stimulation not well-defined; most evidence anecdotal
  • Insufficient evidence for hair-specific application; better-studied peptides available
