With so many conditioners available to purchase, it can be hard finding the right one to get. This article attempts to evaluate the most popular anti-dandruff conditioners based on the most update-to-date understanding of dandruff and seborrheic dermatitis.

To add better perspective and help you find the right anti-dandruff conditioner that’s right for you, the writing is broken down into three primary sections:

  1. What is dandruff and seborrheic dermatitis
  2. General introduction to conditioners and the principles behind them
  3. Review of popular anti-dandruff conditioners (grouped by active ingredient)

The goal of the writing is not to isolate a single “best” formula, but instead provide the tools and knowledge to help assist you in your search for the perfect conditioner. Isolating a specific formula may not be worthwhile, as individual variance exists and peoples experience is likely to differ (one person might react to a specific ingredient, while another does not).

If you have any questions or suggestions along the way, feel to drop them in the comments section at the end of the post. Hope the writing proves useful and your scalp issues are soon to become a distant memory.

Basics of Dandruff and Seborrheic Dermatitis

To start the article off, it may be a good idea to provide a quick review of what dandruff and seborrheic dermatitis actually are and what causes them. Having this background knowledge, can help a more educated buying decision and will hopefully eliminate some of the guesswork.

Additionally, a better understanding of the condition will also help in determining whether or not your issues actually dandruff or seborrheic dermatitis in the first place. In some cases, it may be as simple as product build-up or a more difficult to treat condition such as Psoriasis (if you think it may be Psoriasis, the Psoriasis and Seborrheic Dermatitis section provides some additional insight).

Primary Symptoms of Dandruff

Though some disagreement exists, the majority of medical literature on the subject defines dandruff as a condition characterized by (1, 2):

  • Patches of irritated skin covered with dry flakes and inflammation
  • In some cases, this can be accompanied by strong itch, excessive sebum production, and hair loss

What Causes Dandruff and Seborrheic Dermatitis

Again some disagreement exists and the primary explanation may change in the future, but at this time the main cause of dandruff and seborrheic dermatitis is believed to be the Malassezia yeast.

Quick Introduction to Malassezia

The malassezia yeast is a commensal skin yeast, meaning it is present on the skin of nearly all adults (3). In most cases, the yeast lives on the skin and does not cause any unfavorable symptoms for the host (human). Unfortunately for some of us, it’s present results in the symptoms commonly known as dandruff.

Why this yeast causes issues for some and not others, is not fully understood. The current explanation is related to individual susceptibility (specific immune response, similar to an allergy), skin barrier stability (top layer of the skin is compromised) and a difference in sebum composition (the oily stuff our skin produces) (4).

Focus on Oleic Free Fatty Acids Instead of Malassezia

Though the yeast is the one usually blamed, some investigators have shown that it’s not the yeast themselves that is responsible for the symptoms. Instead, it is the by-products of it’s reproductive/feeding cycle (5, 6).

Malassezia are lipid-dependent yeasts, meaning the utilize oils as their primary food source. During this feeding process, they can oxidize the lipids naturally present on the skin surface and produce free fatty acids as a by-product. Free fatty acids are individual components of lipids.

The one of most relevance is a specific free fatty acid by the name of oleic acid. Oleic free fatty acids in the absence of malassezia have been shown to cause the exact symptoms collectively known as dandruff and seborrheic dermatitis (7). For this reason, researchers have put forward the hypothesis that it is not the malassezia themselves that cause dandruff, but the oleic free fatty acids they leave behind.

Differences Between Seborrheic and Dandruff

The difference between dandruff and seborrheic dermatitis is quite vague. For the most part, dandruff is believed to be a more mild form of seborrheic dermatitis isolated to the scalp (8). Alternatively, some have proposed that seborrheic dermatitis is a physically different condition with unique clinical features (9).

Fundamentals of Dandruff Treatment

Since dandruff and seborrheic dermatitis are both believed to be caused by a yeast (malassezia), the primary treatment approach is through anti-fungal agents. The presence of an anti-fungal reduces the activity of the malassezia and has been shown to be one of the most effective treatment approaches to the condition.

More recent exploration has shown to that an approach that not only aims to reduce malassezia activity, but also improves barrier function amplifies the effectiveness of treatment (10, 11). Thus, focusing solely on reducing the malassezia numbers alone may not be the best approach for the long term.

Basics of Conditioner Formulas and Benefits

While shampoos are formulated to clean the hair and scalp, removing excess oil, dirt, and debris, conditioners are designed to restore moisture to the scalp, improve combability, and supplement the hair with added agents to improve look and feel.

One way to think of it is a conditioner is like a skin cream designed for the hair and scalp.

Basics Components of a Conditioners

Most conditioners are composed of several agents:

  • An oily or wax substances – provide most of the functional benefits
  • Active ingredients – perform specific functions
  • Surfactants – provide foaming and cleansing
  • Emulsifiers – allow oils to become water soluble and improves rinsability
  • Aborsbtion ehanching agents – improve penetration
  • Viscocity modifiers – change the texture for more pleasant Equate
  • pH adjusters/stabilizers – modify the pH value for better skin/hair comptability
  • Colors – more appealing presentation
  • Parfum – provide specific scent
  • Preservatives – ensure the product is shelf stable

The specific balance of each is then adjusted/modifying to achieve a specific outcome required by the formulator. In some cases, some components are removed, while others are emphasized.

Key Component of Anti-Dandruff Conditioners

As discussed earlier, the primary focus of dandruff treatment is to reduce malassezia activity on the skin surface. By reducing malassezia presence, the primary source of oleic free fatty acid production is eliminated and the symptoms are kept in check.

Anti-fungal agents are the most common approach to reducing malassezia activity. The work by inhibiting various components of the yeast cell, causing either cell death or inability to reproduce (different anti-fungal agents work based on different principles).

Accordingly, anti-dandruff conditioners utilize various anti-fungal agents as part of the overall formulation to achieve the clearance of symptoms (12).

The most popular anti-fungal agents used in anti-dandruff conditioners are zinc pyrithione, sulfur, and tea tree oil. Salicylic acid (though not an anti-fungal agent) has also shown some potential in reducing symptoms, but its effectiveness may not be enough on its own it (combination with an anti-fungal enhances effectiveness).

Other more common anti-fungal agents used in shampoos (such as ketoconazole, selenium sulfide, and coal tar) are not usually seen in conditioner formulations. Though the reason is not clear, it’s most likely related to safety concerns when it comes to the leave-on application of these agents (conditioners are usually designed to leave ingredients on the skin).

The dark side of shampoos and conditioners
Evidence suggests that many modern shampoos and conditioners can be damaging to the hair and may cause skin irritation. If overused, these effects can become more pronounced and be counterproductive to your primary objective.

Don’t Forget About Barrier Integrity

Selection of the specific anti-fungal agent used in a formula is usually the area that gets the most focus from individuals looking for a suitable conditioner. However, one often overlooked factor, which may be just as important, is the formulas overall impact on barrier integrity.

To put this back into focus, one needs to understand that malassezia yeast are present on the skin of even healthy individuals. It is only for a subset of us, that the yeast causes the symptoms we know as dandruff and/or seborrheic dermatitis. In these individuals, it is believed that the barrier of the skin is compromised and this results in heightened sensitivity to the oleic acid produced by the malassezia yeast.

Difference between health skin and skin affected by seborrheic dermatitis or dandruff

Thus, in order to control symptoms, it’s reasonable to not only focus on reducing the malassezia activity, but to also focus on improving barrier stability, helping the skin better resist the remaining yeast population.

Anti-Dandruff Conditioner Round-up and Review

It’s difficult to single out any specific “best” conditioner as individuals are likely to react differently to the various ingredients used in any given formulation. Instead, it may be worthwhile to provide a set of evaluation criteria that can help you select the right conditioner.

Criteria for Evaluating Anti-Dandruff Conditioners

First, let’s quickly review some of the factors which I believe have the most weight in terms of finding the right anti-dandruff conditioner:

  • Aggregate used feedback – how well the conditioner is rated across different online sources and shopping platforms, with specific attention for use in dandruff treatment
  • Ingredients used – overall benefit and irritation potential of the ingredients that appear on the label
  • Preservative system – what preservative system has been utilized, it’s safety record, and the chance of irritation
  • Cost and availability – how sustainable is it for real-life usage

Rating of Popular Anti-Dandruff Conditioners

This list of conditioners is not all-inclusive, there are probably other conditioners out there that may be just as good or better than some of the options mentioned.

The conditioners reviewed here are simply those that I believe have unique features which may be of use for the treatment of dandruff. There is one candidate discussed per active ingredient (with the exception of zinc pyrithione, which has two featured candidates).

A list of possible alternatives for each active ingredient is also featured.

Active Ingredient: Sulfur 2% Antidandruff Inactive Ingredient: Petrolatum, Lanolin, Sorbitan, Trioleate, Polysobate-81, Mineral Oil, Menthol, Triclosan, frgrance

A less common conditioner which utilizes sulfur as the active ingredient to reduce malassezia activity. The popularity is likely limited by its strong odor.

  • An extremely basic conditioner that is more like a heavy cream then a typical conditioner
  • Utilizes sulfur for it’s documented benefits of dandruff and seborrheic dermatitis treatment (14)
  • Overall positive feedback, but some individuals complain about the heaviness/greasiness and irritation
  • The packaging (an open lid tub) provides the risk of contamination and spoilage from the environment; thus, Triclosan was used as the preservative
  • Some concerns exist regarding the use of Triclosan in cosmetics, however, it is commonly used in the clinical environment to increase hand washing effectiveness (15, 16)
  • A “light” version exists, but based on the ingredients is also likely to be quite heavy and not drastically different
  • Availability appears to be limited to Amazon and other online retailers
  • The price (~$6) can appear high for the small quantity (57 grams), but since there is no water, a little is likely to go a long way (common conditioners can be 70-80% water)

Positioned as a more natural approach that brings together a long list of herbs and natural actives to provide various hair and scalp benefits.

  • Utilizes salicylic acid to promote the breakdown of the top layer of skin, improving visual appearance and reducing the presence of flakes (17, 18)
  • Overall positive reviews, with specific praise regarding the primarily natural composition of the formula
  • Some have reported lack of results, but this can be expected with any treatment approach
  • In medical reviews, salicylic acid works best if paired with an anti-fungal agent; in this case, tea tree oil has been utilized (19, 20)
  • Overall, the mix of ingredients looks enticing, but it’s hard to say whether or not the variety of extracts have enough functional benefit; the downside, is that the variety also increases the chance for irritation
  • The preservative system depends on a Phenoxyethanol coupled with Ethylhexylglycerin; which is considered a fairly mild approach, but again the chance of irritation exists (21, 22)
  • Though the price leans towards the higher end of the spectrum, it remains affordable with minimal usage
  • Availability is surprisingly good and many stores that have a natural products section carry it

Additional Topics to Consider

Now that you have a good general understanding of seborrheic dermatitis, what makes a good conditioner, and some options that may be worth considering, let’s review some additional factors you may find relevant.

Can a Conditioner Replace a Shampoo

Some individuals question the need for shampoos when it comes to daily usage. Particularly because they are known to strip the skin of the acid mantle it works so hard to maintain and many surfactants (the primary functional component of a shampoo) can cause significant barrier disruption and irritation.

Thus, if your scalp health is poor and your constantly having to fight off bouts of dandruff and severe scalp irritation, it may simply be that you’re over cleansing/cleaning the scalp. Resulting in poor barrier integrity, heightened sensitivity, and excessive transepidermal water loss (moisture loss).

Along this line of thought, many individuals are now looking for ways to reduce their dependence on modern shampoos.

One of these methods is the use of a conditioner instead of a shampoo on a regular basis and only use a shampoo when really necessary (if your hair is getting really dirty). This would theoretically provide all the functional benefits the conditioner has to offer, without stripping the acid mantle and causing too much barrier disruption.

This practice is called “co-washing”, short for conditioner washing.

Many individuals now embrace this approach and you can find a liberal amount of positive feedback spread around online.

Can a conditioner cleanse the scalp?

Though it’s open to discussion, in theory, if a conditioner is designed to rinse well, it may provide some cleansing action. Stearyl alcohol and cetyl alcohol, for example, are considered to be mild surfactants and may provide some cleansing action.

On the other hand, heavier conditioners that do not rinse well would be bad candidates for this approach. As the end result would be a build of conditioner and excessive greasiness.

Switching to the co-wash method may require some initial perseverance
Your skin adapts to your daily routine. If you’ve been using a shampoo on a regular basis your skin compensates by increasing sebaceous gland output (23). Abruptly switching to a conditioner only approach, you’re likely to experience an initial surge in sebum build-up. Give the skin a few weeks time to adjust.

Finding a Good Co-Wash Formula for Dandruff Control

Some possible formulas that may good candidates for using the co-wash approach specifically for dandruff treatment include:

  • Head & Shoulders Moisture Care Dandruff Co-Wash Conditioner
  • Trader Joes Tea Tree Tingle Conditioner
  • Cantu Refresh Apple Cider Vinegar Dry Co-Wash
  • Herbal Essences Naked Cleansing Conditioner – contains zinc pyrithione

Again, different individuals can see drastically different progress from any of these candidates. If something is not working, don’t give up and keep trying with a different approach or active ingredient.

Reversing Dandruff Associated Hair Loss

Many individuals affected by dandruff also suffer from significant hair loss. If your unfortunate enough to fall into this category, reversing the hair loss and improving hair growth can be just as important for you as dealing with dandruff.

This topic has been discussed in significant detail in a previous article:

Reversing Seborrheic Dermatitis and Hair Loss

Though the article doesn’t mention the use of conditioners, some of the points are still relevant when selecting a conditioner:

  • Excessive scale buildup and blockage of hair follicles is likely the primary source of hair loss for individuals affected by dandruff
  • Anti-fungal agents have been shown to improve hair growth and reverse hair loss
  • Hair promoting agents may be helpful in accelerating the rate of hair growth
  • Improving circulation may also prove worthwhile, but too much stimulation and physical aggravation may create the opposite effect

Personal Opinion on Using a Conditioner for Dandruff

Overall, I strongly believe that focusing on improving the skin’s natural protective barrier is the best long-term approach to managing dandruff and seborrheic dermatitis. In this regard, finding and utilizing a dedicated co-wash regimen (ditching shampoo altogether) may hold significant potential (or at-least using conditioner only every second time).

Though I haven’t personally tested the majority of the conditioners on this list, have been experimenting with custom formulations for the past couple of years. As my understanding of the formulating principles that go into a product have grown, it has become easier to make more accurate assumptions as to whether or not the usage outcome would be favorable or not.

If I was to try any of the options mentioned throughout this article, it would be as follows:

  1. Head & Shoulders Moisture Care Dandruff Co-Wash Conditioner
    Though it does contain some questionable components (such as color agents, fragrance, and more aggressive preservative system), the overall formula looks quite solid. It focuses on moisture retention and preservation of the natural scalp lipids may help to jumpstart more long-term stability and progress. And since it was designed and marketed specifically for use as a co-wash, it’s likely to work well as a standalone hair cleanser.
  2. Trader Joes Tea Tree Tingle Conditioner
    This is actually a conditioner that I’ve tried before. Though my progress at that time was minimal, usage time was only limited to a few days. I have a hunch that allowing the scalp to adjust would have ultimately resulted in progress. Solely from the tea tree conditioner options that I’ve seen, this one has the most favorable ingredients list. Packaged at a very reasonable price. If I was to return to this conditioner, it would likely be as a co-wash.
  3. Sulfur8 Medicated – Regular Formula
    An appealing option as it strays away from the more popular anti-fungal agents. It’s likely to be a bit heavy and difficult in terms of application, but it may be a good contender for combination with a more general conditioner. Mixing a small dab together with a more generous amount of regular conditioner, would reduce the irritation potential of the preservative used and allow for easier application. Nonetheless, a shampoo may be required to reduce the heavy residue that’s likely to be left behind.

Alternatively, it may be worthwhile to try ditching anti-fungal agents altogether and strictly focus on repairing the scalp’s own barrier. This would mean experimenting with more natural co-wash conditioners which are designed/developed to be as mild as possible. Keep in mind, going this route can be more challenging and progress is likely to be more difficult to achieve (anti-fungals have a more proven track record at this time).

Summary

The article was my attempt to provide a well-rounded discussion of what goes into the optimal anti-dandruff conditioner (seborrheic dermatitis conditioner) and which options may prove useful.

The key points introduced include:

  1. The primary symptoms of dandruff include patches of irritated skin, dry flakes, inflammation, excessive itch sensation, heightened sebum production, and hair loss
  2. Dandruff and seborrheic dermatitis are understood to be the same condition with key differences in areas affected (scalp versus other areas) and severity of the symptoms (in seborrheic dermatitis, the symptoms are more aggressive)
  3. Malassezia yeasts feed on human sebum and are present on the skin of most humans; they are known to leave behind oleic free fatty acids which can degrade the skin’s barrier function, cause irritation and result in dandruff
  4. Conditioners are primarily designed to supplement the skin and hair with moisturizing elements lost during cleaning (with shampoo or other means)
  5. Anti-dandruff conditioners are designed to reduce the level of malassezia activity (using active anti-fungals), which can result in a reduced amount of oleic free fatty acid and clearance of symptoms
  6. Zinc pyrithione based conditioners are the most popular and widely available in North America; some popular options include Head and Shoulders Classic Clean, Equate (store brand), Nioxin, and Mizani
  7. Sulfur is much less popular for scalp and hair usage, as it has a fairly strong odor and color; there are only two conditioners available, Sulfur8 and Dr. Robaina
  8. Salicylic acid conditioners are aimed to break down the flakes and build-up associated with dandruff, but may not be robust enough to control symptoms altogether
  9. Tea tree oil has been shown to possess significant anti-malassezia potential and has become popular in recent years to increase demand for natural products; the most famous tea tree oil conditioner is the Paul Mitchells, but less expensive alternatives exist
  10. Some individuals have switched to solely using a conditioner to wash their hair, ditching shampoo altogether; this practice is also known as co-washing and may be a perfect fit for dandruff prone individuals as it better preserves barrier function
  11. If you’ve been fighting dandruff for a significant amount of time and face hair loss, emphasis on ingredients which can stimulate hair growth may be worthwhile (discussion in a separate post)

In the end, hopefully, this article has been useful and relevant in your journey to finding the right anti-dandruff conditioner for you. Remember, never give up. If something is not working, switch things up and keep trying.

If you have any feedback on any of the topics discussed or have personal experience with the anti-dandruff conditioners mentioned (or a different approach altogether), please drop a comment below. By sharing our findings with one another, perhaps one day we will have a healthier scalp.
