Hair thinning has many causes, including genetics, hormonal changes, nutritional deficiencies, stress, and underlying medical conditions. GHK-Cu, a copper peptide, may help stimulate hair follicles and improve scalp health. Users typically experience initial shedding followed by new growth around 8 to 12 weeks, with noticeable density improvements by 3 to 6 months.
