Who this guide is for
If your scalp flakes no matter how often you wash it, or you deal with persistent itching, redness and greasy-looking scale along the hairline, the usual suspect is an overgrowth of Malassezia, a yeast that lives on everyone's skin but can flare into seborrheic dermatitis or stubborn dandruff. Cosmetic anti-dandruff shampoos with zinc pyrithione can help mild cases, but when the problem keeps coming back, a shampoo built around a proven antifungal active -- ketoconazole or selenium sulfide -- goes after the yeast itself rather than just managing the flakes. This guide is for anyone who has tried the drugstore basics without lasting relief and wants to compare the real over-the-counter options before buying.

The picks
1. Nizoral Anti-Dandruff Shampoo (1% Ketoconazole)
This is the original OTC ketoconazole shampoo in the US and the benchmark most other antifungal formulas get compared to. Ketoconazole is one of the more clinically studied actives against Malassezia, which is why dermatologists frequently point people toward this exact product first.
Pros
- Widely regarded as the strongest OTC antifungal active available without a prescription
- Works on both scalp flaking and some body-area fungal irritation
- Large, well-established track record with a huge number of reviews
Cons
- Can be drying with frequent use, especially on coarser or color-treated hair
- Scent is more medicinal than a typical cosmetic shampoo
Who should skip it: anyone with very dry, brittle hair who needs a daily-use shampoo, since this is meant for two to three uses a week rather than everyday washing.
2. Vichy Dercos Dandruff Shampoo
Vichy's Dercos line is a dermatologist-facing brand, and this antifungal formula is aimed at people who want a more cosmetic experience -- better lather, a nicer scent -- without giving up antifungal performance for itchy, flaking scalps.
Pros
- Gentler, more pleasant to use day-to-day than many medicated shampoos
- Backed by a skincare brand with a strong dermatology reputation
- Rinses cleanly without the heavy residue some antifungal formulas leave behind
Cons
- Pricier per ounce than basic drugstore antifungal shampoos
- Some users with severe seborrheic dermatitis report needing something stronger
Who should skip it: anyone dealing with a severe, active flare who needs the strongest antifungal concentration rather than a more cosmetic daily option.
3. Pharmbanner Anti-Fungal Shampoo for Folliculitis & Seborrheic Dermatitis
This formula is marketed specifically at Malassezia-driven conditions, including both scalp seborrheic dermatitis and folliculitis on the body, making it a good option for people whose flaking and itching extend beyond just the scalp.
Pros
- Dual-purpose for scalp and body use
- Formulated around multiple antifungal and antibacterial actives
- Good fit for people managing folliculitis alongside scalp symptoms
Cons
- Lower average rating than the more established Nizoral and Selsun Blue options
- Smaller brand with a shorter track record
Who should skip it: anyone who only has mild, occasional scalp flaking and does not need a formula aimed at both skin and scalp fungal issues.
4. Selsun Blue Medicated Antidandruff Shampoo
Selsun Blue uses selenium sulfide rather than ketoconazole, a longstanding antifungal active that has been sold over the counter for decades. It is the most budget-friendly pick here and a reasonable first step before trying something stronger.
Pros
- Selenium sulfide is a proven, long-used antifungal active
- Most affordable option in this roundup
- Very high review volume with a strong average rating
Cons
- Distinct sulfur-like scent that some find unpleasant
- Can discolor light or gray hair with heavy use if not rinsed thoroughly
Who should skip it: anyone with light blonde or gray hair who is worried about tinting, or anyone who dislikes a strong medicated scent.
5. Nizoral 2-in-1 Anti Dandruff Shampoo and Conditioner
Same 1% ketoconazole active as the standard Nizoral shampoo, but formulated as a combined shampoo-and-conditioner for people who find the plain antifungal version too drying or stripping on longer hair.
Pros
- Ketoconazole antifungal power without a separate conditioning step
- Better choice for longer or drier hair than the standard formula
- Simplifies a two-to-three-times-a-week antifungal routine
Cons
- Most expensive option in this list
- Conditioning agents can make it feel slightly less potent than the plain version for very active flare-ups
Who should skip it: anyone who prefers to control shampoo and conditioner separately or who has very short hair and doesn't need the added conditioning step.
How we chose these picks
We focused on shampoos with a genuine antifungal active -- ketoconazole or selenium sulfide -- rather than cosmetic anti-dandruff formulas that only rely on zinc pyrithione or coal tar, since those actives have the strongest track record against Malassezia specifically. Within that group, we prioritized products with substantial review volume and consistently strong ratings, and made sure to include a range of price points and formats, from a no-frills medicated shampoo to a gentler dermatologist-brand option and a combined 2-in-1 for drier hair.
Final verdict
For most people dealing with recurring flaking and itching tied to Malassezia, a 1% ketoconazole shampoo like Nizoral is the strongest starting point with the most evidence behind it. If your hair tends to run dry, the 2-in-1 version is worth the extra cost. Selsun Blue remains the most budget-friendly way to try a proven antifungal active, while Vichy Dercos and the Pharmbanner formula are worth considering if you want a gentler daily-use option or need something that also addresses body-area folliculitis. Whichever you pick, give it several weeks of consistent use before judging results, and check in with a dermatologist if symptoms don't improve or get worse.
Frequently asked questions
What is Malassezia and why does it cause dandruff?
Malassezia is a yeast that lives naturally on the scalp and feeds on skin oils. In some people it overgrows and irritates the skin, speeding up cell turnover and producing flaking, itching and sometimes seborrheic dermatitis.
How often should I use an antifungal shampoo?
Most ketoconazole and selenium sulfide formulas are designed for two to three uses per week rather than daily use, with a maintenance schedule of roughly once a week once symptoms calm down. Always follow the label on the specific product you buy.
Can I use antifungal shampoo on color-treated hair?
Some antifungal shampoos can fade color over time, especially with frequent use. If your hair is color-treated, look for a formula that markets itself as color-safe or limit use to the areas where flaking is worst.
Is ketoconazole or selenium sulfide better for Malassezia?
Both are effective antifungal actives. Ketoconazole tends to have a stronger reputation for stubborn seborrheic dermatitis, while selenium sulfide is a longstanding option for general dandruff and is often gentler for sensitive scalps.
How long before I see results?
Many people notice less flaking and itching within two to four weeks of consistent use. If there is no improvement after a month, or if the scalp becomes more irritated, it is worth checking in with a dermatologist.
