The Similarities: L'Oreal Voluminous is one of the most popular mascara dupes out there and for good reason. It has the same tapered brush shape as the award-winning Diorshow, which helps separate and elongate lashes.

Main Difference: The Dior has a clumpier formulation which tends to dry out easily and produce flakes. L'Oreal goes on much more smoothly and evenly. Both black mascaras look totally indistinguishable when on.

The Verdict: Save your money and go for L'Oreal.
