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.
Endothelin-1
Endothelin-1 is one of the best-studied non-melanocortin regulators of pigmentation in human skin. It is strongly associated with UV-induced tanning responses and pigment disorder biology.
