Can you wash your body with shampoo?

no because shampoo on your body can make you break out because it isn't non-comedogenic

Well I guess some brands could vary. However It shouldn't harm you, might dry your skin some which can be cured before it gets to bad with some lotion. Just use soap/body wash if possible, do not use shampoo as body wash unless you have to. (But Asker, you were right about the first answer. It was removed, the answer now above this is accurate)
