Ketoconazole is why this bottle sits at the top of our list. It's the only shampoo here built on 1% ketoconazole, an antifungal rather than a flake-scraper, and that difference decides a lot when the bumps on your scalp are itchy, inflamed and clustered where dandruff likes to sit. Ketoconazole goes after the yeast that drives that pattern, which is why we treat it as the first thing to try rather than the last resort.
Straight from the bottle the formula is thick, so we work a small amount between wet palms with a splash of water before it goes near the scalp; neat, it's easy to use twice as much as you need. The fresh scent is mild enough to be gone by the time hair dries, and the color-treated claim on the label held up in our testing, with highlighted hair coming out no duller than it went in.
Where it costs you is on the hair, not the scalp. Wash with it more than a couple of times a week and strands start to feel stripped, so we keep a gentler shampoo in the rotation for the days in between and always condition the ends. If your scalp is oily but your hair is fine or dry, that trade-off is the one thing to think through before committing.
Pros
- Targets the yeast behind itchy, bumpy scalps
- Gentle enough for color-treated and processed hair
- Mild fresh scent that fades after rinsing
Cons
- Leaves hair feeling stripped with frequent washes
- Small 7 fl oz bottle next to 11 to 13.5 oz rivals
Our default for scalp acne: the only ketoconazole formula here, and the one we reach for when bumps arrive with itch and flaking.
