Both are copper peptides with the same histidine-lysine-copper structure
It was suggested that the peptide may promote the elongation of hair follicles and the proliferation of dermal papilla cells (DPCs), which are specialized fibroblasts with a potential to increase the growth and development of hair follicles
AHK-Cu Peptide and Alopecia Research The study examined the potential of two formulations containing growth factors and peptides such as vascular endothelial growth factor, basic fibroblast growth factor, insulin-like growth factor-1, keratinocyte growth factor, and copper tripeptide 1 and related peptides such as AHK-Cu, suspended in a sterile vehicle

(3) AHK-Cu Peptide and Hair Follicle Development Researchers posit that the tripeptide AHK-Cu may potentially stimulate the proliferation of dermal fibroblasts, a type of cell that produces substances like vascular endothelial growth factor (VEGF), which are considered to be crucial for the growth of blood vessels
