I suppose that another continuing series here is going to be what I would call "vitamins in the shampoo"; the nonsensical combination of unrelated features in a single product for no reason other than that it sounds good in advertising. Vitamin-fortified shampoo is certainly not harmful but it does no good, either. The ostensible purpose of it is to "nourish the cells which make up hair", but in fact those cells are dead. There's nothing to nourish.
Funny (from Steven).
