I bought nixion 1 from super cuts and now I ordered nioxin 7 from EBAY in gallon containers and they don't smell the same and when I use the conditioner/scalp therapy it does not have minty smell or that refeshing feel ( people who have used it know what I am talking about ) to it. Nioxin 1 is is for fine thinning hair and nioxin 7 is for course, color treated or permed hair. If I did'nt buy it off ebay I wouldnt be concerned but I have bought bunk nikes off ebay before does anyone have any suggestions as to tell the authenticity of this product ?
