MHarris once commented that Nioxin or other “polysorbate based hair cleaners” (also “other polyscorbate based hair conditioners”) will work to remove sticky pheros.
But he also cautions about disturbing your natural bacterial culture on your skin with too much soap, and advocates rinsing, except for spot cleaning with Nioxin/etc.
