The hair-relevant evidence discussed here is predominantly in vitro or ex vivo, and much of the most-cited follicle data was generated with the related peptide AHK-Cu rather than GHK-Cu
In vitro studies demonstrated follicle stem cell activation, and limited clinical data reported increased hair density and thickness at 0.2% concentration (Park et al., 2011)

Anti-aging peptides specifically refer to compounds that interact with mechanisms governing cellular senescence, extracellular matrix production, oxidative stress response, and telomere maintenance
Here is what women most commonly report: Injection site reactions
