Contains: Revivogen Scalp Therapy Formula (3 Month Supply), three 2 oz. Bottles (6 oz.or 180 ml) Formulated by a dermatologist, this all-natural hair regrowth regimen offers a safe and effective alternative to other options currently available. The main active ingredient in Revivogen has been clinically proven to reduce DHT production even more effectively than Propecia . It activates the hair follicles, while blocking the androgen receptors to prevent DHT uptake. Under the suppressive effects of DHT, the hair follicles become thinner and finer until the hair is permanently lost. Within 90 days of using Revivogen, a significant decrease in hair loss and thickening of existing hair may be noted. Within three to six months of use, the revitalized hairs will make the scalp look fuller and denser. With continued use, the hair quality will continue to improve and stay healthy with best results occurring after 12 to 18 months. Once maximum results are obtained, the daily use of Revivogen can be decreased to few times a week for maintenance purposes.
