iv been using rogaine for about a year. Rogaine is not an HDT blocker and is therefore not a cure for hair loss. I might have grown 6 hair while being on it. I am losing hair in my frontal region. Procerin sounds like the next best thing. It sounds safe and effective. It seems absurd to me that something as simple as regrowing hair is so hard for modern science to figue out. I promise there will be more effective ways to regrow hair in the future such as hair cloning but for now id shop around for safe products other than rogaine
