- GHK-Cu (Copper Peptide)
- Activates VEGF, inhibits TGF-β1, stimulates collagen remodeling in dermal papilla
- 2–5 millimolar topical solution
- Phase II trial: 18% terminal hair count increase at 24 weeks (Yonsei University)
- Twice daily
- Most researched peptide for follicle regeneration. Strong evidence for anagen extension
- BPC-157
- Modulates growth hormone receptors, enhances angiogenesis, accelerates wound healing
- 250–500 micrograms per application
- Synergistic with GHK-Cu: 14.2 hairs/cm² vs 8.1 solo (IJMS 2026)
- Post-microneedling, 2–3x weekly
- Enhances vascular support. Most effective combined with mechanical stimulation
- Thymosin Beta-4 (TB500)
- Promotes cell migration, actin polymerization, tissue repair signaling
- 2 milligrams subcutaneous (not topical)
- 35% faster recovery from telogen effluvium (subcutaneous admin)
- Twice weekly injection
- Accelerates post-shedding recovery. Limited evidence for pattern hair loss prevention
- PTD-DBM (Platelet-Derived Biomimetic)
- Mimics growth factors in platelet-rich plasma without requiring blood draw
- 1–3 millimolar topical
- Early-stage trials show 9% density increase at 12 weeks
- Daily application
- Emerging alternative to PRP. Less invasive, more consistent dosing
