Copper peptides (GHK Cu) have been studied for decades for their role in tissue repair and that same biology applies to hair. Research shows GHK Cu may help strengthen existing hair follicles, reduce BFNB Enhances Hair Growth in C57BL 6 Mice through the Induction of EGF and FGF7 Factors and the PI3K AKT Catenin Pathway GFC is prepared from the patient's blood in a closed system where platelets are activated ex vivo to release growth factors like PDGF, VEGF, EGF and IGF1, which are then injected into Thermodynamically stable ionic liquid microemulsions pioneer pathways for topical delivery and peptide application ScienceDirect PDF) The effect of tripeptide copper complex on human hair growth in vitro
