January 2026 in “Journal of Clinical Case Studies” This case report explores the use of copper tripeptide (GHK-Cu) combined with photobiomodulation (PBM) for treating androgenetic alopecia (AGA) in a 46-year-old male. GHK-Cu is known for its collagen-stimulating and antioxidant properties, but its effectiveness is limited by molecular instability and poor transcutaneous penetration. PBM was used to enhance the delivery and activity of GHK-Cu, potentially increasing tissue permeability and cellular uptake. The patient showed noticeable improvement in hair growth after 14 days of treatment, suggesting that this combined approach may be effective for AGA. However, as this is a single case without trichoscopic evaluation, further controlled studies are needed to confirm these findings and understand the synergistic effects of GHK-Cu and PBM.
