Head & Shoulders vs Nizoral Anti-Dandruff Shampoo
First and foremost, it's worth establishing the fact that both shampoos are intended to "control the symptoms of dandruff". What mainly sets them apart, though, is the difference between their active ingredients (with the Head & Shoulders Shampoo containing Zinc Pyrithione—or Piroctone Olamine in Europe—and the Nizoral Shampoo instead containing Ketoconazole). In essence, this comparison boils down to a question of "which anti-fungal ingredient works best against dandruff?", but there are a couple of other differences to explore first.
Diving into their formulas, we discover that both shampoos contain Sulfates. These are known as 'surfactants' and they give shampoo that thick lather that we associate with cleansing hair. That said, they are also known for not being particularly gentle to the scalp. Neither are free from coloring or fragrance, either, and while these aren't the most egregious inclusions (there's certainly more irritating ingredients in other shampoos out there), but it's worth stating given the medicinal nature of these particular products.
Returning to the topic of their active ingredients, there's no real contest between the two in terms of strength or efficacy since Ketoconazole (present in the Nizoral Shampoo) is far more potent than Zinc Pyrithione. Since there's also no drawbacks of Ketoconazole tolerability-wise (unlike with, say, a Selenium Sulfide shampoo), this point alone makes Nizoral the better choice to treat dandruff symptoms regardless of mildness or severity.
Both shampoos are renowned the world over, and arguably equally as immensely popular. While we appreciate the fact that this isn't necessarily a guarantee of quality, it certainly is a strong indicator, and we feel comfortable stating that you're in safe hands whenever you invest in either brands' hair care products. With that said, on paper Nizoral is clearly the better choice due to its more effective active ingredient, and therefore wins our recommendation.
