Query: This stuff is the greatest!

There is no substitute for this product; the other ones are garbage so be sure to only use the No Rinse brand, because it truly is superior.Have been using this product for several years and really like it. There are times my head needs shampooing but my body doesn't need washing, so this instant shampooing is very convenient. Easy to use and a little bit of product goes a long way (at least with my very very short hair).
