I use this all the time on my color treated hair to gently clean so I don't use too much of the more expensive products.  (I have dyed my hair red and if you have ever done so, you know how fragile it is and how readily it wants to wash out.)  It also works magic in the nether regions, completely replacing Summers Eve wash in my shower, my husband loves using it too.  I also use this on my cats and it helps get them nice and clean without drying out their skin and rinses very clean so I don't worry about them ingesting soap as they frantically lick themselves dry.
