Mechanisms of Hair Growth Stimulation Mechanisms involve: VEGF and HGF (hepatocyte growth factor) production stimulation Wnt/-catenin signaling pathway activation Dermal thickening promotion Improved scalp circulation Reduced follicle inflammation DHT Protection Mechanisms DHT protection occurs through copper ions showing up to 90% inhibition of type 1 5-alpha reductase at specific concentrations, with greater specificity for type 1 (hair-damaging) than type 2 (prostate)
However, topical products containing GHK-Cu (the copper-bound form of the same GHK peptide) are commercially available and work through the same follicle-stimulating mechanisms documented in this and other copper peptide studies
Your body naturally produces glutathione, but levels decrease with age, stress, and toxin exposure, which is why supplementation with glutathione may help
