I have had Alopecia Universalis for 45+ years. While anything is possible, I have heard more so called cure claims than I can remember. The only thing predictable about this condition is its complete unpredictability, unless you have it to my extreme. I took Prednisone, as prescribed by a dermatologist not an endrocronologist, way back the late 60's and almost all my hair came back, for about a month. When I stopped taking it, like our standard doctor told me to, because of all its side effects, it all fell out again, for good. Just don't buy it. Mark Hansen
