A bestselling anti-dandruff shampoo.

What is the best dandruff shampoo for your itchy, dry and flaky scalp? Nowadays, there are many popular choices. These range from Nizoral anti-dandruff shampoo, to Neutrogena T/Gel, to Head & Shoulders.

The below updated list of dermatologist recommended 14 best dandruff shampoos in 2024 is applicable for both men and women. Some of the recommended brands have many decades of research behind their formulas.

Make sure to also read my post on natural dandruff treatments. Several recent studies suggest that the condition of the scalp can impact hair growth. In particular, killing the Malassezia (P. ovale) fungi and yeast is proven to benefit scalp hair growth. Most hair loss sufferers tend to often get inflamed scalp conditions. On a related note, also make sure to read my post on demodex mites and hair loss.

My Experience with Head & Shoulders

Head & Shoulders Clinical Strength Dandruff Defense.
Head & Shoulders Clinical Strength Dandruff Defense Shampoo.

In 2022, I chose to try out Head & Shoulders Clinical Strength dandruff defense shampoo for intensive itch relief. Over the course of 20 years, I have used various Head & Shoulders shampoos for my frequent dandruff problems. The Head & Shoulders line is considered American’s #1 dandruff shampoo brand.

I have also used many dermatologist recommended hair loss shampoos to help soothe my inflamed scalp.

However, in recent years, I tended to almost always favor the very effective Nizoral shampoo to treat my scalp flakes. However, in 2022, it started to lose its effectiveness for me. Perhaps because the Malassezia (Pityrosporum) fungus started to develop tolerance to Nizoral? Moreover, the Nizoral makes my scalp a bit too dry at times.

Switching to the Head & Shoulders extra strength anti-dandruff shampoo has been a great success so far. My scalp flakes always go away for at least two or three days after each use. I also do not seem to get excessive scalp skin dryness after using this product. I hope this result continues in 2023 and beyond.

Anti-Dandruff Ingredients

Key ingredients in dandruff shampoos that reduce scalp flakes and itching include:

  • Salicylic acid.
  • Sulfur.
  • Zinc pyrithione (ZPT).
  • Coal tar.
  • Selenium sulfide.
  • Ketoconazole.
  • Ciclopirox olamine.
  • Piroctone olamine.
  • Clobetasol.
  • Climbazole.

Product effectiveness can vary depending upon: whether you have a dry scalp versus oily scalp (overproduction by sebaceous glands); presence of Malassezia yeasts on the scalp; whether you are male or female; and your own propensity for allergic immune reactions to certain ingredients. Some people also like to use carbonic acid based shampoos.

For best results, make sure to lather and leave the shampoo on your scalp for at least a few minutes before rinsing. This is especially true for the bestselling Nizoral shampoo.

Nizoral A-D Anti-Dandruff Shampoo

Nizoral A-D

One of my favorite best dandruff shampoo products with ample scientific backing behind its efficacy. Numerous positive Amazon, Walmart and Reddit reviews. The key active ingredient in this over-the-counter shampoo is Ketoconazole 1%, which is an anti-fungal agent with anti-dandruff and anti-androgenic properties. The last of these aids scalp hair growth according to a number of studies.

Nizoral attacks the Malassezia microbe, the main cause of dandruff in many instances. It also reduces hairfall in some cases due to anti-androgenic properties. Nizoral comes in a fairly small bottle, but still lasts for many months with twice a week usage. I do not recommend more frequent usage or else you can exacerbate scalp dryness and end up with brittle hair quality and texture. You can also get Nizoral 2% medicated shampoo with a prescription.

Neutrogena T/Gel Therapeutic Shampoo

Neutrogena T/Gel

The key active ingredient in this popular dermatologist recommended T/Gel product is 2% coal tar extract. Accompanying instructions suggest just once a week usage to be ideal in combating dandruff, seborrheic dermatitis as well as psoriasis. The coal tar gives this product an unusual color and keratolytic properties that can smoothen and improve inflamed scalp skin.

Some users do not like the smell of this medicated anti dandruff shampoo and also complain about dyed color treated hair fading. Coal tar also helps slow down the shedding of dry skin cells and can reduce scalp acne. Note that Neutrogena T/Sal is a different product made by the same company, but is also highly rated and contains salicylic acid 3%.

Head & Shoulders Clinical Strength Dandruff & Dermatitis Shampoo

Head & Shoulders Clinical Strength

Over the years, Head & Shoulders has produced more varieties of dandruff and hairfall shampoos than any other company. Their most popular product for preventing scalp flakes is this clinical strength shampoo for stubborn cases of dandruff. The key active ingredient in it is selenium sulfide 1%, which reduces scalp fungus and bacteria at the root.

This product offers lasting relief from scalp itching and flaking. You can also find a number of other highly rated and reviewed Head & Shoulders dandruff shampoos on Amazon. After lathering, make sure to leave the product on your scalp for at least 5 minutes before rinsing and styling. Head & Shoulders also sells an anti-dandruff and anti hairfall two-in-one shampoo. However, I am skeptical in general about shampoos that claim to reduce hair fall. L’Oreal Paris also makes a fall resist 3X anti-dandruff anti-hair fall shampoo.

JASON Natural Dandruff Relief Shampoo

JASON Natural

Although not as well known as the above three listed products, Jason Natural is a unique pH balanced largely natural product. It contains colloidal sulfur 2% and salicylic acid 2% as the two main active ingredients to tackle dandruff and seborrheic dermatitis.

Formulated with additional beneficial herbal and natural ingredients that improve scalp health, including: cooling aloe vera, apple cider vinegar, jojoba oil, methylsulfonylmethane (MSM), olive oil, rosemary oil, seaweed extract, tea tree oil and vitamin E.

Head & Shoulders Classic Anti-Dandruff

Head & Shoulders Classic Clean (Walgreens Link)

Head & Shoulders came out with a zinc pyrithione (or pyrithione zinc) based shampoo all the way back in 1961. To this day, the company still makes anti-dandruff shampoos that are based on this original active ingredient, in a zinc pyrithione 1% formulation. This key ingredient helps inhibit scalp yeast and fungus growth. Note that you can also purchase stronger more effective zinc pyrithione 2% shampoos such as DHS zinc shampoo.

A cleaner scalp helps provide relief from uncomfortable itching and flaking; reduces redness and scaly skin; and removes product buildup. All beneficial in those with thinning hair. You can pick up various Head & Shoulders shampoos at your local Walgreens or CVS pharmacies. This classic clean version is paraben free.

Selsun Blue

Selsun Blue Medicated (Walmart Link)

Selsun Blue moisturizing anti-dandruff shampoo with aloe is Sanofi’s bestselling product to fight visible flakes and dry hair. It contains selenium sulfide 1% (also spelled sulphide) . The aloe will soothe and moisturize sensitive scalps.

Also popular are Selsun Blue medicated dandruff shampoo and conditioner 2-in-1; and Selsun Blue Active 3-in-1 dandruff shampoo, which contains salicylic acid 2% to help fight acne and buildup.

Sanofi also makes a Selsun Gold shampoo and Selsun 2.5 shampoo that both contain selenium sulfide 2.5%. However these products do not seem to be sold OTC in the US. Perhaps you can get them via a prescription.

Pura D’or

Pura D’or MD Anti-Hair Thinning Shampoo

Pura D’or has taken the hair loss world by storm over the past decade. The company’s shampoo products contain a wide range of beneficial ingredients. Moreover, Pura D’or is especially renowned when it comes to its product packaging and marketing. The Pura D’or Maximum Defense (MD) anti-hair thinning shampoo contains both 0.9% ketoconazole and 0.5% coal tar extract.

Both are known to fight dandruff. However, do note that some of the reviews suggest missing ketoconazole in newer formulations. Make sure to verify the exact ingredients before purchasing. This shampoo also contains a proprietary herbal blend of 19 key ingredients that nourish the scalp. This includes saw palmetto, nettle extract, He Shou Wu (Fo-Ti), red Korean seaweed, hibiscus, clary sage, black cumin seed, tea tree, pygeum bark and rosemary.

Dove DermaCare Anti-Dandruff Shampoo

Dove DermaCare Scalp Dryness & Itch Relief

Dove is a globally renowned cosmetics brand name. The Dove DermaCare dandruff shampoo is formulated with active pyrithione zinc to resolve dryness and itching in dandruff-prone scalps. Its mild pH balanced formula helps avoid moisture depletion, and leaves hair flake free, smooth, and less frizzy.

Nioxin Scalp Recovery

Nioxin Scalp Recovery Anti-Dandruff

Nioxin is a respected brand, but not known for its dandruff shampoos. However, their scalp recovery line of products is a popular product to treat itch and flaky scalps. It contains zinc pyrithione, green tea extract, scalp soothing peppermint oil and biotin. The product claims to prevent recurrence of flaking and itching associated with seborrheic dermatitis.

Paul Mitchell Tea Tree Special

Tea Tree Special

A number of readers have mentioned the highly rated Paul Mitchell Tea Tree Special Shampoo. I have heard about this product a lot over the years, and might even have tried it some years ago. You can often purchase it at local hairdressers and beauty salons for a discount.

Besides tea tree oil, the product also contains peppermint and lavender according to the manufacturer’s website. Note that Head & Shoulders also sells a popular tea tree oil containing anti-dandruff shampoo that is currently on sale at Walmart.

OUAI Anti-Dandruff

This sulfate-free hair and scalp shampoo and cleanser targets flaking with exfoliating salicylic acid. It is a great choice for oily hair. Moreover, like glycerin, aloe vera and coconut oil in this product intensively hydrate and soothe the scalp. The end results is reduced itching, redness and irritation.

What Shampoo Gets Rid of Dandruff?

The best dandruff shampoo (with or without conditioners) will at least temporarily relieve your dry, itchy, flaky scalps. Scaly scalp skin conditions and inflammation are especially common in balding regions of the head. For those suffering from recurring dandruff episodes, treatment choices can be confusing.

A first solution defense is to look for an effective dandruff treatment shampoo for your hair care needs. Most of the leading products (both non-prescription and prescription strength) work effectively in both men and women. Some will work better than others for color treated hair, greasy oily hair, excessively dry hair, grey hair and curly hair. Others will work better on oily scalps versus dry scalps.

The tingling scalp and embarrassing white flakes on dark clothing cause a lot of stress in people suffering from this problem. For some, the dandruff comes and goes in patches. For others, it represents a daily problem of high skin turnover that can be genetic in nature.

Dry indoor winter heating and washing your hair too often can further exacerbate the flaking, itchiness and dead skin cells. Note that dandruff is one particular manifestation of a condition called seborrheic dermatitis. People in hot weather countries such as India will need a different shampoo to those in rainy countries such as the UK.

Over the years, I have had many episodes of severe dandruff and scalp itching and burning, especially during dry weather days. Although these are not always frequent, I have tried and tested most top rated medicated anti-dandruff shampoos over the years. And I have also experiments with many natural treatments such as apple cider vinegar.

How to Treat Scalp Flakes and Dryness

Bestselling Dandruff Shampoos.

A number of scientifically sound dandruff treatment approaches can be used to target and control scalp flaking.

Most of the below selected best dandruff treatment medicated products have their own unique key ingredients. These have their own distinct mechanisms of action to give you a smooth flake-free scalp.

I try to alternate between several different antifungal and dandruff shampoos every month. My reasons for doing this are so as to:

  1. Not get side effects from the overuse of any one product with its key anti-dandruff ingredient(s).
  2. Avoid having my scalp becoming immune to the effects of certain ingredients due to overuse. This can lead to dandruff recurrence.

Try to purchase products that do not include sulfates, parabens, silicones, phthalates, diethanolamine (DEA) and artificial dyes. I try to also buy products that are never tested on animals.

In addition to dandruff (see reddit), many of the below shampoos also work to treat other skin conditions of scalp buildup and flaking such as eczema and psoriasis. Usually, these products work by reducing the overproduction of skin cells when mild to moderate. Note that several of the products contains sulfates and other potentially harmful ingredients that cause side effects in some people. For babies with cradle cap, it is recommended to use less harmful baby shampoos.

Other Popular Anti-Dandruff Shampoo Choices

  • Also popular option is the color-safe shea moisture African Black Soap bamboo charcoal deep cleansing shampoo. This is a popular dandruff shampoo for African American hair. It does not contain sodium lauryl sulfate (SLS), which can harm colored hair. Key ingredients include African black soap, bamboo charcoal, tea tree oil and willow bark extract. Soothes itching while revitalizing dry hair and skin. This product was never tested on animals. On a related note, Briogea sells a charcoal and coconut based shampoo and scalp scrub product.
  • Some people have mentioned that ciclopirox olamine based shampoos may be effective for moderate levels of dandruff. However, I have as yet not found any popular over-the-counter dandruff shampoo that is based on ciclopirox olamine. Also effective is piroctone olamine.
  • Also popular are argan oil and apple cider vinegar based anti-dandruff shampoos. Head & Shoulders sells a highly rated apple cider vinegar containing 2-in-1 shampoo and conditioner product.

Dandruff Shampoo Soap Bar

A very interesting product that is worth mentioning here is Ethique’s highly rated and popular dandruff shampoo soap bar. This Ethique Heali Kiwi shampoo bar is eco-friendly and helps tackle dandruff and itchy scalps. The bar (various colors for different hair types) contains cocoa butter, coconut oil, neem oil, karanja oil and oatmeal. Each solid bar is equivalent to 3 bottles of liquid shampoo.

Ethique is renowned in New Zealand for its eco-friendly environmental footprint. Plastic waste is a huge global problem, especially in the oceans. According to Ethique, 80 billion plastic bottles of shampoos and conditioners are disposed of around the world each year. This product is much needed and highly recommended.

Frequently Asked Questions

Below are some frequently asked questions about the best dandruff shampoos for your itchy flaky scalp.

What is the most effective shampoo for dandruff?

Our picks for the most effective dandruff shampoo are as follows: Nizoral A-D; Neutrogena T/Gel; Head & Shoulders Clinical Strength; Jason Natural; Selsun Blue; Pura D’Or MD; Dove Dermacare; Nioxin Scalp Recovery; and Paul Mitchell Tea Tree.

What ingredients are the most effective in anti-dandruff shampoos?

The most effective ingredients in dandruff shampoos are ketoconazole, zinc pyrithione, salicylic acid, coal tar, selenium sulfide, sulfur, tea tree oil and ciclopirox and clobetasol.

How often should you use a dandruff shampoo?

If a mild shampoo does not control your dandruff, a medicated dandruff shampoo should be used two to three times per week. If this causes excessive scalp dryness, you can reduce the frequency and wash your scalp with milder moisturizing products on other days.

Is it OK to use a dandruff shampoo every day?

For most people, daily use of a dandruff shampoo will lead to excessive scalp dryness and skin problems. This is especially true if the product contains harsher ingredients such as Sodium Lauryl Sulfate, Sodium Laureth Sulfate, Parabens, Polyethylene Glycols and Alcohol.

Nizoral Anti-Dandruff Shampoo

Nizoral is an extremely popular dermatologist recommended ketoconazole 1% based dandruff shampoo. It also has modest hair growth properties.

As of December 2023, Nizoral has almost 88,000 reviews on Amazon, with an average rating of 4.6 out of 5 stars. It costs just $14.28 for the smaller 7 fl oz (200 ml) bottle. This is a very affordable price when compared to other leading dandruff shampoos. The 14 fl oz (400 ml) bottle is currently priced at $27.57 on Amazon.

A November 2023 study from India successfully developed and tested a novel anti-dandruff shampoo incorporated with ketoconazole-coated zinc oxide nanoparticles. The researchers wanted to improve on existing ketoconazole (KTZ) based shampoos with weak skin epidermis absorption and permeability. The prepared nanoparticles showed enhanced activity against Malassezia furfur compared to regular KTZ (1%).

A May 2022 study from Brazil found that ketoconazole shifts the scalp skin lipid profile, affects Malassezia lipid metabolism and favors biotin-producing bacteria. Biotin improves inflammatory conditions.

Nizoral Shampoo

Nizoral A-D Shampoo for Dandruff Treatment.
Nizoral Shampoo 1% Anti-Dandruff.

Nizoral shampoo (1%) is one of the highest rated and reviewed anti-dandruff shampoos that you can buy without a prescription. I rank it as one of the 15 best hair loss shampoos in the world. You can buy it at most stores, including Walmart (4,500 reviews), Target (4,700 reviews) and CVS (3,700 reviews).

Nizoral A-D Anti-Dandruff Shampoo with ketoconazole 1%, is consistently rated as one of the best products to counter dandruff, scalp itching, flaking and fungus. We all shed millions of dead skin cells every single day. However, some people have excessive skin turnover on the scalp, leading to dandruff.

Nizoral Ketoconazole 2 Percent Shampoo
Nizoral Ketoconazole 2% shampoo for dandruff. Prescription only in the US, but available off-the-counter in Canada and the UK.

Nizoral (often misspelled as Nizarol) can improve psoriasis symptoms, scaly scalp skin, yeast infections and even foot fungus. Some reports suggest it can also benefit fungal acne, although facial usage is not recommended.

A small bottle of this highly rated antifungal anti-inflammatory product will last for many months. Note that Nizoral 2% shampoo comes in a red bottle and is a different product.

The Nizoral 1 percent shampoo is an over-the-counter product, while the medicated 2 percent shampoo requires a prescription in the US. In the UK and Canada, you can purchase the latter off-the-shelf at pharmacies and on Amazon. On the UK site, this formulation has 27,600 reviews with an average rating of 4.6 out of 5 stars. Note they write their units as 20 mg/g, which is the same as 2%. The bottle contains only 60ml of liquid.

Also worth noting, Nizoral shampoo can help reduce hair loss to a moderate extent due to its anti-androgenic properties. See the studies listed at the end of this post that support this point. Other popular hair loss shampoos include Revivogen and Shiseido Adenovital.

Ketoconazole 1%: The Active Ingredient

The list of ingredients in Nizoral can be found in the FDA label pdf. The key active ingredient is ketoconazole 1%. Ketoconazole (abbreviated KCZ or KTZ) also has some anti-androgenic properties.

To date, only two drugs with very different mechanisms of action have been approved by the US FDA to treat hair loss: Finasteride (Propecia) and Minoxidil (Rogaine).

Nizoral Shampoo Ingredients.
Nizoral shampoo ingredient list. Includes Ketoconazole 1% to fight dandruff.

However, Ketoconazole (the active ingredient in Nizoral shampoo) also has some hair growth benefits. It is an imidazole anti-fungal agent that counters dandruff and scalp inflammation.

Ketaconazole will likely never be officially approved to treat hair loss, because its manufacturer is unlikely to ever file for approval. With sales of Nizoral already going strong globally, it is probably not worth going through all the rigorous expensive clinical trials to get little added benefit.

Ketoconazole is a synthetic drug that is used to treat fungal infections. In particular, the drug flushes out Malassezia (formerly known as Pityrosporum) yeast fungus. Malassezia has been implicated in problems such as dandruff and seborrheic dermatitis. The latter leads to clogged hair follicles.

Other names for similar fungal infections and overgrowth of the scalp include Pityriasis Versicolor, Pityrosporum Ovale and Malassezia Furfur. Skin conditions such as tinea and ringworm may also benefit from this product.

Ketoconazole was originally available in tablet form, but has since also been developed into topical forms such as creams, lotions and shampoos. Note that oral ingestion of ketoconazole can lead to serious side effects such as liver damage in some patients. However, topical cream and ketoconazole shampoo usage have generally not been linked to such side effects.

My Nizoral Experiences for Scalp Itching

A large proportion of hair loss sufferers seem to also get itchy and dry scalp conditions, including dandruff and seborrheic dermatitis. I am one of those, although the severity and frequency of my symptoms is moderate.

Some years ago, I started using Nizoral 1% anti dandruff shampoo for my itchy inflamed scalp instead of other regular shampoos. I was absolutely amazed at its effectiveness in completely eliminating my scalp itching and dandruff for at least a day or two after each application. My hair looked better and healthier, and it seemed like my daily hair shedding rate also declined.

Update: December 2023 — These days I use Head & Shoulders medicated, although just once every three weeks. Nizoral was making my hair a bit too dry and lifeless.

There is some evidence that ketoconazole blocks the synthesis of dihydrotestosterone in the scalp and acts as an antagonist of the androgen receptor (see list of studies at the bottom of this post).

Nizoral Conditioner

Nizoral now also sells a popular deep moisturizing hair conditioner product. It is supposed to counter the drying effects of Nizoral shampoo.

The conditioner is free of sulfates, parabens, artificial fragrances and dyes. Among the key ingredients in the conditioner (which contains seven moisturizers) include:

  • Shea Butter.
  • Jojoba Seed Oil.
  • Peppermint Oil.
  • Tea Tree Leaf Oil.

How often Should you use Nizoral Shampoo?

I would recommend using Nizoral shampoo no more than twice a week in order to prevent excessive skin dryness. You also do not want your scalp microflora and fungi to become immune to the effects of ketoconazole. Overuse will make your scalp skin excessively dry and make your hair brittle. I would recommending rotating between several different products among the best dandruff shampoos available.

When you do shampoo with Nizoral, make sure to keep it on your scalp for at least 3-4 minutes after lathering and before rinsing. Some people recommend rinsing hair in cold water rather than hot water in the shower. The former prevents excessive moisture loss and skin drying out.


In 2012 or so, it seemed like US drug stores and pharmacies such as Walmart, Walgreens and CVS stopped carrying Nizoral shampoo, at least when it comes to the most popular blue bottle variety (see photo further below). I thought this was because of the warnings related to side effects from taking oral ketoconazole. I later found out that the problems with availability were due to the shampoo’s manufacturer having production issues at its main plants, rather than any issues related to side effects.

Luckily, I had sufficient supplies to last me for a while, since you only need a small amount of Nizoral shampoo to make a big difference. Most people do not need to use it more than twice a week. However, this shortage continued in 2013 and I then had to pay a significant premium to buy it from a seller on ebay. A lot of people took advantage of this situation by selling their surplus Nizoral stock online in 2012 and 2013.

In 2014, Nizoral came back on the market and the shortages finally ended. No supply issues have occurred since that time. You can read numerous favorable reviews of Nizoral online.

Nizoral Side Effects

As long as you are not taking Nizoral (i.e., Ketoconazole) orally, side effects are usually limited and transient. The main side effects that can arise from using Nizoral shampoo include:

  • Itchy scalp.
  • Dry scalp skin.
  • An unnatural hair texture and feel.
  • Rashes, hives and other allergic reactions.
  • Red inflamed eyes in case the product accidentally gets in there.

Ketoconazole and Hair Loss Studies

You can find many studies that suggest Nizoral causes a reduction in hair loss and thinning. Ketoconazole has anti-androgenic properties that could slow the progression of androgenetic alopecia (aka male pattern baldness). Below are some such studies in order of oldest to most recent:

In June 2018, Germany’s Stada acquired Nizoral from Johnson & Johnson. For more recent information, see Nizoral’s official Instagram page.
