i agree that the cone is water soluble, so it will wash out with shampoo. but if you suffer silicone buildup easily you might find it doesnt work. even after one application my hair did what it always does with any cone (amodimethicone and dimethicone in particular) - it frizzed outa nd lost all curl pattern. but arc angell works fine so i'm sure its the amodimethicone, despite that it's water soluble.
