Repairs Damaged Hair and Strengthens Strands: Hair damage from heat styling, chemical treatments (like coloring and perming), and environmental stressors can weaken the hair cuticle, leading to breakage, split ends, and dullness

The factor responsible turned out to be a small copper-binding tripeptide whose endogenous concentration declines with age from roughly 200 ng/mL at age 20 to 80 ng/mL at age 60. The 50-year research arc that followed makes GHK-Cu one of the most thoroughly characterized small peptides in the literature

But few molecules have this combination of safety, decades of data, and broad-spectrum benefits across skin, bone, organs, and even cognition

GHK-Cu provides that guidance
