Among copper peptides for hair growth, GHK-Cu has been shown to: Stimulate dermal papilla cells, which are critical for initiating new follicle growth (Pyo et al., 2007) Increase follicle size and shift dormant follicles into the anagen (growth) phase (Pyo et al., 2007) Promote the production of glycosaminoglycans and collagen, improving scalp health and structure (Pickart & Margolina, 2018) Reduce pro-inflammatory markers like IL-6 and TNF-alpha, calming the environment around follicles (Pickart et al., 2015) Enhance vascularization, ensuring oxygen and nutrients reach the follicle root (Dou, 2020) These actions help explain why GHK-Cu is considered one of the most effective peptides in regenerative dermatology
