Minoxidil with Azelaic and Retinoic Acid

Dr. Rassman,
Could you please comment on the the various minoxidil solutions offered by Dr. Lee (www.minoxidil.com) and whether his claims are substantiated. Specifically, I am very curious to hear your opinion regarding the use of azalaic and retinoic acid (either with or without minoxidil) as regrowth stimulants and DHT inhibitors. Are they of any benefit and, if so, are they likely to be any more effective than minoxidil alone?

Generic minoxidil may have enhancers added and they include axelaic acid and retinoids. I have no opinion in their isolated use, but when combined with minoxidil, they increase the blood supply to the area of application. This is a like a minor burn and it can be irritating to the skin. It, to my knowledge, is not a DHT inhibitor and I do not personally believe that it will make minoxidil more effective.
