GHK-Cu shows meaningful evidence for hair benefits it extends the anagen (active growth) phase of hair follicles, increases dermal papilla cell activity, and may inhibit the follicle miniaturization signals that contribute to thinning hair
Treatments each have an arm, which might include a particular dosage, a placebo, or another type of care
