Nizoral A-D is an over-the-counter anti-dandruff shampoo whose active ingredient is 1% ketoconazole, an antifungal that targets the yeast associated with dandruff. The label directs use every 3–4 days for up to eight weeks, then as needed, with a regular shampoo in between. Dermatologist creators and long-term users credit it with controlling stubborn flaking and itching where zinc pyrithione shampoos fell short. The trade-offs are a sulfate (SLES) base that can feel drying on lengths and a strict usage schedule.

Best for

Persistent flaking and itching that zinc or selenium shampoos have not controlled
A twice-weekly scalp treatment alongside a regular shampoo

What we love

Recommended by dermatologist creators and long-term users

Worth knowing

Sulfate (SLES) base can leave lengths feeling dry without conditioner
Strict usage schedule and drug-label warnings, including a doctor check for children under 12

Beauty score out of 10. Brands can’t pay for placement — ever.

Results30%8.8
Ketoconazole is a well-studied anti-dandruff active, and long-term users and dermatologist creators consistently report controlled flaking and itching within weeks.
Formula & ingredients20%8.6
The only OTC dandruff shampoo with 1% ketoconazole, per the brand; the SLES-based cleanser and fragrance are basic and can be drying on lengths.
Texture & experience15%6.8
A pearlescent shampoo with a fresh scent, but it needs a twice-weekly schedule and many users follow with a separate conditioner to offset dryness.
Value20%8.6
About $17 for 7 fl oz at Walmart, and because it is used only every 3–4 days a bottle lasts many weeks, keeping the cost per wash low.
Community love15%8.9
A perennial recommendation on dandruff and scalp forums and from dermatologists on YouTube, often described as the product that finally worked.

r/Haircare

Think of Nizoral as a scalp treatment more so than a shampoo. … Do this 2 or 3 times a week. By the time you get through the bottle, your itch should be long gone.

r/Haircare

one thing worth mentioning is that Nizoral can be pretty drying on the hair itself. I´d focus it on the scalp rather than rubbing it through the lengths, especially if you have long hair.

r/Haircare

Nizoral made my scalp sooo dry and actually made my dandruff worse.

u/Steezyy23r/Haircare · 2026-105Source

r/Haircare

I use Nizoral (the dandruff shampoo) once every two weeks, and it has been tremendously helpful for me. I still have to wash my hair every 2-3 days, but it’s better than needing to do it every day.
