Peppermint Oil - Peppermint oil is an essential oil, and it is primarily used to promote circulation. As stated above, with hemp oil, this improvement in blood circulation is necessary to deliver oxygen and nutrients to the hair follicles to encourage growth. It may even reduce some hair loss. This minty ingredient sometimes causes a tingly sensation, which is nothing to worry about. It is easy to add to any beauty product, but TruVarin already has the correct dose for users.
