How this review was made: We did not test this shampoo. This verdict is based on the product's over-the-counter label text and a few published reviews and expert comments listed at the end.

A well-regarded antifungal option when ordinary dandruff shampoos fall short

The active ingredient, ketoconazole, is an antifungal that targets the yeast linked to dandruff, and two dermatologists quoted in media coverage describe it as effective. A telehealth brand's review cites an older trial where about 80 percent of users saw less dandruff within four weeks versus about 20 percent on placebo. Buyers quoted in sponsored coverage are very positive, but that coverage is anecdotal. Limits: it is a short-course routine, not for broken or inflamed scalp, and the label says to ask a doctor if there is a rash or no improvement within 2 to 4 weeks.

Buy it again if you…

  • have persistent dandruff that ordinary shampoos have not controlled
  • are willing to use a medicated shampoo a few times a week
  • want an over-the-counter antifungal option

Skip it if you…

  • have a broken, inflamed or very irritated scalp
  • are pregnant or breastfeeding without asking a doctor
  • want a hair-loss treatment (it is not one)

This review summarizes published coverage and the product label and is not medical advice. Persistent flaking, redness, a rash or hair loss can have other causes, so check with a doctor or pharmacist, especially if you are pregnant, breastfeeding or have a scalp condition. Follow the label directions.

Stop if it is not working.Ask a doctor if a rash appears or the problem worsens or does not improve within 2 to 4 weeks.

How it holds up over time

The label describes a course of up to 8 weeks and then use only as needed, so many people keep a bottle for flare-ups. We did not find long-term studies.
