How do the brains feel about the Nexxus Dualiste Shampoos and conditioners? They are dual sided shampoos and conditioners, one side has supposed color protection and another has either anti-breakage, intense hydrating, or volume boosting ingredients. However a quick glance at the ingredients shows that the color protecting side is nearly identical to the other benefiting side. Is this really an effective hair product or is it just a marketing ploy?
