Research Overview
Minoxidil
Minoxidil has extensive human evidence for scalp hair regrowth in androgenetic alopecia and is a standard comparator in hair-loss trials. Its follicle effects are thought to involve potassium-channel modulation, vascular changes, and prolongation of the growth phase.
Argireline
Acetyl hexapeptide-3 has both in vitro and small human-cosmetic studies supporting a reduction in wrinkle depth or wrinkle appearance. Its best-supported role is as a topical cosmetic peptide rather than a systemic drug.
