The official website of Provillus states that the product is designed with the natural herbs to control the DHT production over the hair scalp to prevent the hair loss. The product is composed of daily supplement and a hair regrowth spray. The manufacturers of the product claim that the product blocks the DHT formation over the scalp and provides the body with essential nutrients to prevent the hair loss and promote the hair regrowth.
However, due to the lack of compelling evidence in these other conjectured hair loss solutions, it may be more beneficial and cost effective to spend your money on Propecia (finasteride) for men only and Rogaine (minoxidil) that has helped balding men and women worldwide.
