Head & Shoulders Head & Shoulders Classic Clean Dandruff Shampoo vs Nizoral Anti-Dandruff Shampoo
Effectively a tie. The scores are too close for the rubric to call a meaningful winner.
Score, factor by factor
Concern46 / 5546 / 55
How much genuine, cited concern the ingredients carry, weighted by how much of each is likely present and whether the product stays on or rinses off. Commonly feared but low-concern ingredients cost nothing.
Transparency12 / 2012 / 20
Whether the full ingredient list, and any fragrance, are actually disclosed. An undisclosed "fragrance/parfum" blend hides its allergens and costs points.
Formulation restraint18 / 2515 / 25
Needless irritant or allergen load for the product type. A clean, purposeful formula scores well without any "free-from" theater.
PlainScore76 / 10073 / 100
The three factors summed: concern out of 55, transparency out of 20, formulation restraint out of 25. Higher is lower concern.
Left column: Head & Shoulders Head & Shoulders Classic Clean Dandruff Shampoo. Right: Nizoral Anti-Dandruff Shampoo. The bold number wins the factor.
