The Provillus® Hair Regrowth Solution contains 5% Minoxidil, the only FDA-approved topical ingredient clinically proven to regrow hair in men and women. Minoxidil is a "potassium channel agonist." It contains the chemical structure of Nitric oxide (NO), a blood vessel dilator, and may be a nitric oxide agonist. This may explain Minoxidil's ability to stimulate hair growth and treat hair loss. Since Minoxidil is a nitric oxide related compound it was suspected to act via activation of Guanylate cyclase, an enzyme involved in vasodilation, however there are no reports of cGMP or PKG activation to date.
