Medicated shampoos

1. Nizoral Anti-Dandruff Shampoo (1% Ketoconazole)

Best for: Stubborn dandruff and itchy scalp · Price range: Mid-range (7 oz) Ketoconazole is an antifungal that targets the yeast behind most dandruff, and Nizoral is the best-known shampoo that contains it over the counter. Use it two or three times a week and let the lather sit for 3 to 5 minutes. Many people see fewer flakes within a couple of weeks.

Keep in mind: It can dry out your hair, so follow with conditioner on the lengths, and it costs more than other dandruff shampoos.

2. Selsun Blue Medicated Anti-Dandruff Shampoo

Best for: Heavy flaking when other shampoos stop working · Price range: Budget (11 oz) Selsun Blue Medicated uses selenium sulfide, a strong anti-dandruff ingredient that slows how fast scalp skin flakes off. It’s a smart one to rotate with Nizoral or a zinc shampoo if your dandruff keeps coming back.

Keep in mind: It has a medicinal smell, and selenium sulfide can discolor blonde, gray or color-treated hair if you don’t rinse it out well.

3. Head & Shoulders Classic Clean (1% Pyrithione Zinc)

Best for: Mild dandruff and everyday use · Price range: Budget (28.2 oz) The classic. Pyrithione zinc is gentle enough to use every day, and this XL bottle makes it one of the cheapest dandruff treatments per ounce. It’s ideal for mild flakes or for keeping dandruff away once a stronger shampoo has cleared it.

Keep in mind: The scent is strong, and it may not be enough on its own for severe dandruff or seborrheic dermatitis.

4. Neutrogena T/Sal Therapeutic Shampoo (3% Salicylic Acid)

Best for: Thick, scaly buildup · Price range: Budget (4.5 oz) T/Sal uses salicylic acid to loosen and lift thick, stuck-on scale. It’s a good choice when flakes form patches rather than a light dusting. Use it a couple of times a week, alternating with an antifungal shampoo like Nizoral.

Keep in mind: Salicylic acid is drying, and the bottle is small for the price.

Gentle and leave-on options

5. CeraVe Hydrating Anti-Dandruff Shampoo

Best for: Dry, itchy scalp with light flakes · Price range: Budget (12 oz) CeraVe’s dandruff shampoo combines pyrithione zinc with ceramides to treat flakes without stripping your scalp. It’s fragrance-free, which helps if your scalp is sensitive. It’s our pick if most dandruff shampoos leave your scalp tight and itchy.

Keep in mind: The lather is mild, so it may not be strong enough for heavy flaking.

6. Head & Shoulders Royal Oils Daily Moisture Scalp Cream

Best for: Textured or coily hair washed less often · Price range: Budget A leave-on scalp cream with 1% pyrithione zinc and coconut oil. It’s made for curly and coily hair that isn’t washed every day, so you can treat dandruff between wash days. Apply it straight to the scalp in sections and massage it in.

Keep in mind: It’s rich, so it can feel heavy on fine or straight hair.

How to make a dandruff shampoo work

• Massage it into the scalp, not just your hair, and leave it on for 3 to 5 minutes.
• Rotate ingredients. If a shampoo stops working, switch to one with a different active ingredient.
• Keep going. Once flakes clear, use the shampoo once or twice a week to stop them coming back.
• Dandruff or dry scalp? Dandruff flakes are usually larger and slightly oily. Dry-scalp flakes are small and white, and a gentle shampoo like CeraVe suits them better.
• See a doctor if nothing helps after 4 to 6 weeks, or if you have red patches, pain or hair loss.

Worried about thinning too? Nizoral appears in our guide to the best shampoos for thinning hair.

FAQ

What is the strongest dandruff shampoo you can buy without a prescription?

Can I use dandruff shampoo every day?

Gentle pyrithione zinc shampoos like Head & Shoulders and CeraVe are fine daily. Use ketoconazole and selenium sulfide two or three times a week.

Does dandruff cause hair loss?

Dandruff itself doesn’t, but heavy scratching and scalp inflammation can make shedding worse.

Is dandruff shampoo safe for colored hair?

Most are, but selenium sulfide can discolor light or color-treated hair. Rinse well, or choose ketoconazole or zinc instead.
