Heheeee!!! nooooooo this will NOT come out with just water!! That's one of the reasons I love it/hate it.
The first time I used it I overdid it and took three different shampoos to get out it!! The second time I used less and it was great, but this is why it leaves my hair moisturized and looking great for days on end. I think I got two week hair with this before when I used it for two strand twists.
