Melatonin, the pineal gland hormone and a strong antioxidant, has long been known, particularly in animal-experiment based research and the wool-producing industry, to be a potent regulatory neuroendocrine substance in relation to hair growth, hair color and hair cycle, depending on light periods, seasonal rhythms, environmental factors and reproductive rhythms. Nevertheless, the biological mechanisms of this extremely versatile hormone, especially with regard to human hair follicles, are not fully understood. In recent years, however, essential knowledge has been gained on the melatoninergic system of the skin, melatonin levels in keratinocytes and hair follicles, extrapineal intrafollicular melatonin synthesis and noradrenalin-induced increase in synthesis, as well as hair cycle-dependent expression of the membrane-bound melatonin receptor MT2 and the nuclear receptor RORα. Functional data on the growth of human hair both in vitro and in vivo show that melatonin might play an essential role in hair physiology.
