This source-based comparison does not add ratings or recommend a winner.
- GHK-Cu 1–2% topical
- Follicular angiogenesis, VEGF upregulation, stem cell Wnt signaling
- 18–33% increase in controlled trials
- Stacks with minoxidil, finasteride, microneedling without mechanism conflict
- Strong adjunct. Addresses vascular and inflammatory deficits that DHT blockers and potassium channel openers don't target
- Minoxidil 5%
- Potassium channel opening, adenosine receptor activation
- 12–18% increase in controlled trials
- Synergistic with GHK-Cu (different mechanisms)
- Gold standard but limited by vascular dilation only. Doesn't rebuild capillary networks
- Finasteride 1mg oral
- 5-alpha-reductase inhibition (reduces scalp DHT 60–70%)
- 10–15% increase in vertex density at 1 year
- Compatible with GHK-Cu. Targets upstream hormonal cause
- Most effective for androgenetic alopecia but doesn't address non-DHT miniaturization factors
- Platelet-Rich Plasma (PRP)
- Growth factor delivery (PDGF, IGF-1, VEGF)
- 20–30% increase at 6 months (highly variable)
- GHK-Cu may amplify PRP effects by sustaining angiogenesis between sessions
- Promising but expensive and protocol-dependent. GHK-Cu offers similar angiogenic signaling at lower cost
- Microneedling (1.5mm)
- Wound healing response, collagen induction, enhanced penetration
- 15–25% increase when combined with topicals
- Essential for GHK-Cu penetration. Increases absorption 3–10×
- No direct hair growth mechanism alone but dramatically improves peptide delivery
