Interesting! I have the same question as Pam - dandruff shampoos vary in ingredients i think...DH uses head & shoulders, maybe I'll try that. For years I've used Oxyclean on my running clothes, and it takes out the stink.
We're big fans of Tide w/Febreeze and borax (which also helps soften our horribly hard water). I have found no combo that cuts the stink better than this.
