    Product Description

    Minoxidil is a pyrimidine derivative that was originally developed as an anti-hypertensive agent and unexpectedly found to stimulate hair growth. Minoxidil directly affects arteriolar smooth muscle to decrease vascular resistance in part by opening ATP-sensitive potassium channels.1,2 It can activate cyclooxygenase 1 (AC50 = 80 μM), which is expressed in the dermal papilla of hair follicles, increasing prostaglandin E2 production in BALB/c 3T3 fibroblasts and human dermal papilla fibroblasts.3

    WARNING This product is not for human or veterinary use.
