Washing my hair with shampoo and conditioner in bath

Shampooing your hair is in desperate need of a wash. Washing twice will strip your hair for two months by accident. But I tend to have greasy hair, face, and oily body so I'd like to try out some new bath products. It sounds too good to be true, but conditioner washing, aka “co-washing,” has. If you're totally confused about the “right way” to wash your hair & restore it's elasticity and shine.
