Research by dermatologist Dr. Alex Khadavi zeroed in on Revivogen, as the best formula to counter- act the harmful effects of DHT, the baldness creating hormone that are naturally produced from some enzymes present in the human scalp. This hair loss product on application binds the DHT, thus preventing it from directly acting on the hair follicles which would otherwise have lend to thinning of the hair.. The natural ingredients present in the Revivogen are harmless to the skin and also does not interfere in other hair care activities like hair coloring. Continuous application of Revivogen for a year would stop hair loss.
