Certain people are genetically predisposed to hair loss when exposed to a by-product of testosterone called dihydro-testosterone (DHT). DHT is made in the body by both men and women and new research has proven that this hormone is responsible for the progressive miniaturization of the hair follicle. The Patent Pending Revivogen Formula is a revolutionary, all-natural solution in the fight against hair loss. Unlike its competitors, Revivogen is based on the latest medical breakthroughs into the cause and treatment of hair loss and is made with natural ingredients that have been scientifically proven to reduce DHT production, block the androgen receptors and stimulate hair growth. Revivogen is used topically, can be used by both men and women and has no known systemic side effects.
