I have used Salac for over 10 years and it works wonders. Depending on where you live, I have found it over the counter at Drug Emporium. If you cannot find it on the grocery store shelves, then all you have to do is order if from the pharmacy. No prescription needed. Also, get the wash. They have a foam kind but I like the wash the best and use it with a back brush when taking a shower each morning. Also works well for chest, neck, etc.
