Ketoconazole is why Nizoral leads this list. It's an antifungal that goes after the yeast behind most persistent flaking, rather than a wash that lifts flakes off the surface, and at 1% it's the only over-the-counter shampoo here with that active. If your flakes return a few days after every wash, that distinction is the entire decision.
We rate it the best default in this group for exactly that pattern, and we were also struck by how little it asks of your hair: it's gentle enough for color-treated, chemically processed, and gray hair, so a color appointment doesn't rule it out. One practical note — the liquid is thick and doesn't spread on its own. Add a splash of water in your palm before you work it in, or you'll use twice as much getting it past the back of your head.
Because this is a few-times-a-week treatment rather than a daily wash, the seven-ounce bottle stretches further than the size suggests, and the cost per wash lands closer to the drugstore picks than the shelf price implies. It's still the bottle we buy when the flakes are winning.
Hair shedding is the one caveat worth knowing about, and it cuts both ways: it can settle, and it can also pick up. If thinning already worries you, start with a single bottle and give it a few weeks before committing to more.
Bottom line: For flaking that keeps returning, this is our pick: ketoconazole goes after the cause, and the formula is gentle on color-treated hair.
