Hair Growth Research Stack

GHK-Cu stimulates dermal papilla cell proliferation, activates Wnt/beta-catenin signalling (a key pathway in hair growth cycling), increases VEGF production for follicular blood supply, and promotes extracellular matrix production around follicles. Research shows it can extend the anagen (growth) phase and increase hair shaft diameter.

Oxidative stress is a significant factor in hair follicle miniaturisation and premature catagen (regression) phase transition. Glutathione, as the body's master antioxidant, protects follicular cells from ROS damage, preserving the follicular microenvironment and supporting the growth conditions that GHK-Cu stimulates.

Hair follicle research protocols typically require 12-16 weeks for measurable changes in hair shaft diameter, follicle density, and anagen/telogen ratios. The hair growth cycle is slow, so shorter protocols may show molecular markers (gene expression, growth factor levels) before visible morphological changes.
