Minoxidil through sulphat metabolites can open potassium channels, the opening potassium channels can increase the hair follicles growth. The study of the effects minoxidil on human epidermal keratinocytes and hair follicles with different culture conditions and markers proliferation, found that minoxidil with micro molar concentration can stimulate proliferation both type of cells and all culture condition, whereas minoxidil with milimolar concentration will inhibit cell growth. In addition, several studies have also reported an association minoxidil to vascular effect and stimulating VEGF can promote the increase hair follicle
