“So why does this product appear markedly more efficacious than others on the market such as Rogaine® and Propecia®? A review of product ingredients discussed in this article shows that higher strengths of Minoxidil (5%) are more effective than lower (2%). The addition of the Retinoic Acid, Tretinoin, increases the efficacy of Minoxidil. A topical steroid improves efficacy and reduces irritation, and a 5-alpha reductase blocker increases efficacy. Formula 82M contains all of these previously proven ingredients and now in a Propylene Glycol-free base. However, more importantly, their proprietary solubilizing and stabilizing process appears to markedly improve drug delivery and shelf life.”
