Peppermint oil is an essential oil widely known for its pleasant smell and stimulating effects. It acts as an astringent and helps remove excess sebum from the scalp. When used as an oil on the skin, peppermint oil acts as a vasodilator and increases blood flow to the area of application. This ability to encourage circulation makes peppermint oil a potential hair growth enhancer when used on the scalp. Peppermint oil produces a cooling effect when placed on the skin because it contains menthol.
