Would doctors recommend using nothing at all, just warm water, for e.g. showering or bathing (not talking washing hands after changing diapers or so)? Or why not? It seems to be hard to find actual studies about the effects. In fact I have yet to find one, might be my search skills are lacking. From anecdotal experiments I don't see much difference and no negative effects. I don't like the smell anyway, my skin nor hair seems to care, in fact seems to produce less oil overall probably because it doesn't have to counter removal anymore, and as far as I and close friends can tell my body still smells the same.
