Kaela,
I know I"ve seen a definition of a 2-in-1 shampoo and they are relatively new in the hair care world. Relatively new meaning that they really started being developed about 1980.
A true 2-in-1 shampoo serves the function of both shampoo and conditioner. No separate conditioner is supposedly to be needed. Some fulfill this and others do not. BUT, the product is specifically manufactured in a way that the result is NOT a grease pool. In practice, this happens and sometimes it does not. The conditioning agents are suspended while the washing function is being served. This is only part 1 of the definition, too.
Creme of Nature is marketed as shampoo, detangler and conditoner. I know on my bottle it says it can be used without a separate conditioner. I've used it this way, too, and usually with it, I will just add any extra condtioner to my ends. I do this regardless of what a product says about a 2-in-1 function.
I know people who have added some conditoner to their shampoo, but it's not like the Pert Plus by any means. If you want to do this, I think it would certainly be an experiment. I've never had the inclination to want to do this.
In my opinion, Pert Plus for Kids[Bananaberri] is a great 2-in-1 shampoo. It's mid-way between the Creme of Nature Regular and the Creme of Nature Ultra Moisturizng. It smells just like a banana-berry smoothie and utterly softening.
