Derma-IonX has helped a lot of skin conditions. Taken internally, the homeopathics in it help the skin to detoxify and heal. The oligotherapeutic base also helps stimulate the enzymes systems in the body to help with healing starting from the inside. Be sure to use Derma-IonX topically as well. It may take some time for hair to regrow so be patient. To help speed things along it is a good idea to add in a few other things. Derma-IonX will aid better utilization of the other supplements and provide faster results. The supplements I use are: digestive enzymes with each meal, a probiotic such as Purina's Forti Flora, and a fish oil supplement daily.
