Ketoconazole is the reason this one sits at the top of the guide. Nizoral is the only shampoo here built on it, and it works on a different principle from everything else in the set: rather than lifting flakes off the surface, it goes after the Malassezia yeast that drives most dandruff in the first place. That distinction matters more than any lather or scent — you're treating the cause rather than the symptom, and the difference shows up in how long the flakes stay gone.
What earns it the top spot is how little it asks of you. It's gentle enough for color-treated, chemically processed, and gray hair, the fresh scent is genuinely pleasant rather than medicinal, and you use it as a treatment alongside your usual shampoo rather than as a wholesale replacement for it. Strong actives usually come with a penalty attached; this one mostly doesn't.
The penalty it does have is dryness. Scalps that are already tight and over-washed can come out of it feeling stripped, and hair can read as brittle until it's conditioned. Keep it off the ends, follow with conditioner from the ears down, and don't run it on consecutive days.
One practical note worth having before your first wash: the liquid is thick and doesn't spread across the scalp on a first pass. Wet your hands, work it in sections, and leave it a moment before you rinse, or you'll use twice as much as you need to.
Bottom line: Buy this if you want to treat the cause of your dandruff rather than manage the flakes, and you don't mind a small bottle that lives beside your regular shampoo.
