I think it comes down to the 'no tears' factor. When you feel they can switch to regular shampoo without getting it in their eyes. I have been using kids shampoo and then my conditioner for a long time. The kids' conditioners just aren't thick enough and don't do a very good job. My kids also like the fun scents that the kids' shampoos come in so we'll probably be using them for a while.
