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.
ACTH
ACTH activates melanocortin receptors on melanocytes and can increase pigment synthesis. It is widely used as a reference peptide in studies of tanning, adrenal biology, and hyperpigmentation.
