Any redhead knows that color can be short-lived (even if born with it) and of all tones fades first. A fusion of red helps both orange and blue-based hues stay true.
An extra-mild formula (to avoid stripping) with a low pH (to neutralize oxidation and smooth the cuticle) leaves a mere trace of enhancing color without damaging hair. A rather low lather (it’s a myth that a head full of suds means thorough washing) is a sign of the kindest possible cleansing.
