Head & Shoulders vs Selsun Blue Anti-Dandruff Shampoo

Comparison

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 Selsun Blue Shampoo instead containing Selenium Sulfide). 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 the Head & Shoulders Shampoo contains SLS + SLES (Sodium Lauryl Sulfate and Sodium Laureth Sulfate) and the Selsun Blue Shampoo contains ALS + ALES (Ammonium Lauryl Sulfate and Ammonium Laureth Sulfate). These are known as 'surfactants' and they give shampoo that thick lather that we associate with cleansing hair, but with them being Sulfates they are known for not being particularly gentle to the scalp. ALS is *much* less irritating than SLS, though, due to its larger molecular size, so the Selsun Blue Shampoo definitely pulls ahead in this regard.

Returning to the topic of their active ingredients, there's no real contest between the two in terms of strength or efficacy since Selenium Sulfide (present in the Selsun Blue Shampoo) is far more potent than Zinc Pyrithione. This still leaves us with a bit of a decision, though, because Selenium Sulfide is overkill for mild cases of dandruff, to the point where it can actually cause irritation due to its strength if left on for too long (so much for that ALS vs SLS point!). Our recommendation would be to only opt for the Selsun Blue Shampoo if your dandruff looks or feels *severe*—in which case, it's also worth knowing that the alternative Head & Shoulders Clinical Strength range includes Selenium Sulfide.

The Head & Shoulders Classic Clean would almost certainly be the better choice to keep *mild* flakiness and dandruff at bay (due to its weaker—but still effective—active ingredient), and for most people this will be the case. It offers 72 hour protection from flakes, dryness, and itchiness, and is suitable for regular use. Head & Shoulders also happens to be the #1 shampoo brand in the world (*according to P&G), so you know that you're in safe hands whenever you invest in their hair care products.

In summary: if you're looking for a shampoo to treat mild dandruff, the Head & Shoulders Classic Clean Shampoo is definitely the one for you. If you're looking for a shampoo to provide intensive treatment for severe dandruff, then the Selsun Blue Anti-Dandruff Shampoo will be far better suited.
