A Holistic Guide to Dandruff and Dry Scalp

A Holistic Approach to Dandruff: Supporting a Healthy Scalp From the Inside Out!

It’s often talked about as though it’s simply genetics or something that randomly happens. But what if you discovered that there are often deeper-rooted causes that contribute to dandruff?

Dandruff is one of the most common concerns we hear about when it comes to hair and scalp health, yet it is often treated as though it exists only on the surface of the scalp.

This is how it usually goes: perpetual flakes appear, so you slather your head with dandruff shampoo, scrub your scalp until every last speck is rinsed away, watch the dandruff come back, (rinse)and repeat.

But your scalp is part of the broader ecosystem of your body. It is living skin connected to your immune system, stress levels, hormones, environment, nutrition, hair-care habits, and overall health.

Yes, the right products can make a significant difference, but lasting scalp health often requires looking at your body’s entire ecosystem to better understand why you may be dealing with persistent dandruff.

Dandruff vs. Dry Scalp: What's the Difference?

A dry scalp usually lacks moisture. It may feel tight after washing and throughout the day, itchy, and even sensitive, with smaller flakes that are typically dry. The hair itself may also feel and look brittle!

Cold weather, indoor heating, hot showers, overwashing, harsh/toxic shampoos, and irritating hair products may all contribute to dry scalp.

Dandruff, alternately, is often considered a form of "seborrheic dermatitis". If you've ever experienced it, you will know what I am talking about! It may involve white or yellowish flakes, itching, burning, overall irritation, and even oiliness!

Some research points to a naturally occurring yeast called Malassezia appearing to play a role in some cases of dandruff, but dandruff is not simply an infection.

Research increasingly shows it as a more complex connection between scalp microbes, oil production, the skin barrier, personal sensitivity, and environmental factors.

The Gut-Scalp Connection

When we think about dandruff, it's easy to immediately look at what is happening externally. Our shampoo, wash schedule, styling products, and scalp treatments, etc.

Yeah, those things do matter, buuuut... they usually are not the entire story when you're dealing with chronic dandruff. That was the case for me too... more on my personal scalp story below!

Your gut and skin communicate through what is called the gut-skin axis. Yes, I know... There she goes harping about the gut again. You guys, it's because it SERIOUSLY matters! I'll never shut up about it.

Anyways, this communication involves the gut microbiome, immune system, metabolism, hormones, inflammatory responses, and the protective barriers of both the gut and skin. Again, the body is an ecosystem.

The trillions of microorganisms living within the digestive system help break down food, produce specific compounds, interact with the immune system, and support the body’s internal environment.

Research into the gut-skin axis points to imbalances within the gut influencing immune activity, inflammation, and thus skin-barrier function. Starting to see how it's all connected?

This does not mean every single case of dry, dandruffy scalp is caused by poor gut health. But, the info we're discussing in this blog does remind us that the scalp cannot be separated from the health of the rest of the body.

It is important to note that topical products, such as medicated dandruff shampoos, can help manage what is happening externally, especially when dandruff is particularly uncomfortable.

Maybe you're relying on them right now for relief! However, when it comes to supporting long-term scalp health, you know us around here at SBA, we always like to begin with the inside and work outward.

By making consistent changes to your diet, lifestyle, and hair-care routine while giving your scalp time to respond, you may actually find that you do not need to rely as heavily on emergency dandruff shampoos.

Instead, products like our Revitalize Hair & Scalp Serum and Nourish Conditioner can become part of a holistic and supportive long term scalp routine.

My Dandruff and Psoriasis Story

So, I couldn’t write this blog without including my own journey with severe dandruff and psoriasis. My dandruff started at a very young age and gradually became worse and worse, until what I found myself dealing with was straight-up plaque psoriasis.

I had large patches all over my body, but especially on my scalp. It also didn’t help that I am a picker. Oh boy, did I pick my scalp. I picked it so badly, and it only made everything worse.

I remember trying absolutely everything: no shampoo, using only apple cider vinegar as shampoo, no conditioner, dandruff shampoos, special medicated cream shampoos, not washing my hair for weeks, and avoiding all hair-styling products. Nothing worked.

Eventually, I began losing hair around my temples because of how severe the dandruff and psoriasis had become. I remember looking at my hair on my wedding day and noticing how bald I appeared on the worst side of my head.

I also remember how uncomfortable the hairspray felt and how badly it stung while my wedding hair was being styled. Looking back, I now see that I was definitely losing hair because of the constant cycle of dandruff, psoriasis, and picking.

Alongside all of this, I was struggling with several health issues that followed me from childhood into adulthood, along with new issues that developed as an early adult.

It just felt like one health problem was stacking on top of another, with a scaly, flaky, and sometimes even bloody scalp to top it all off. Yeah, my scalp looked like a war zone a lot of the time. It was really painful.

Eventually, I became fed up with feeling so horrible and decided to see an integrative medicine specialist and naturopath the same year I got married. We ran several tests and uncovered quite an onslaught of issues, many of which involved my gut.

I pretty much immediately cut out all my known and possible triggers, changed my diet almost overnight, and began following a specific gut protocol to address the issues we had found.

A few months into changing my diet and following the protocol, I realized that my psoriasis patches and overall scalp dandruff had decreased dramatically. After about a year, my scalp issues were completely resolved.

I genuinely could not believe that the severe scalp problems I had dealt with for most of my life, which had felt like a lifelong sentence, were completely gone! Felt like a miracle honestly.

It has now been about six or seven years since I have dealt with any significant scalp issues, other than the occasional dry patch when I repeatedly eat known triggers or neglect proper nutrition.

This is why I like to bring up my own story here... Because it showed me just how deeply connected gut health can be to the health of the skin and scalp! And yes, my body psoriasis completely resolved as well.

Nutrition for a Healthy Scalp

If you research the topic, you’ll find that there is no single “dandruff diet,” nor is there one magical food that will eliminate the issue. Current research on diet and seborrheic dermatitis is still developing.

However, based on my personal experience, there are certain foods that can be triggering or inflammatory for some (or a lot) people.

I am not a nutrition expert, doctor, or dandruff specialist, but many people, myself included, do not process certain foods particularly well.

For me, those have included pasteurized dairy, most sources of gluten, certain types or preparations and quality of legumes and corn, industrialized soy products, industrialized seed oils, and a few other foods.

Some people may tolerate these foods without noticeable inflammation or side effects, but for the most part, I cannot.

When I repeatedly eat them, I can absolutely feel the difference and may experience flare-ups of dandruff and psoriasis on my scalp and face.

The key word here is repeatedly. If I accidentally or intentionally consume one of these foods every once in a while, it is usually not a big deal. Sometimes I go crazy and purposefully eat my trigger foods.

I am not scared of these foods. At this point, I simply know my personal triggers and how much of these things I can get away with before I feel and see it. Balance, right?

So, yeah, after doing a lot of work to support my body, I can now tolerate occasional exposure to these foods much better than I could before. But in the past? Wow, not so much.

Again, I am not an expert or a doctor, so I am not telling you to start cutting everything out of your diet. However, the current state of your gut, along with foods that may not be supporting it well right now, is certainly something worth considering when it comes to addressing your scalp issues.

Prebiotic and Probiotic Foods

Prebiotics are certain fibers that feed beneficial microorganisms already living within the gut. Prebiotic-rich foods include garlic, onions, leeks, asparagus, apples, properly prepared legumes, among other natural foods from the earth.

Fermented foods such as raw milk, or organic dairy like yogurt and kefir, sauerkraut, kimchi, and traditionally fermented vegetables can provide live microorganisms!

*P.S. Homemade sauerkraut is EXTREMELY easy and inexpensive to make. It is literally just organic cabbage and salt! I make huge batches at a time, and they last for months. My current batch is about a year and a half old and still tastes amazing. Fermented foods are something else.

The cool thing is, you don't need to eat enormous portions of these fermented foods. Begin with small, consistent servings (if your body tolerates them well!)

Prioritize Healthy Fats

You already know how much we love healthy fats! Whole food (fatty meat, avocado, salmon with skin on, etc) and cold-pressed, non-industrialized high quality oils like avocado, olive, and flax are so good for the skin and scalp! The naturally occurring Omega-3 fatty acids support skin-barrier and are anti-inflammatory.

Other nourishing fats, such as avocado and extra-virgin olive oil, can also be included as part of a balanced diet. We love some cold-pressed, first harvest olive oil around here.

Eat Enough Protein and Minerals

A healthy scalp (and overall skin!) depends on adequate nourishment. Protein, zinc, iron, selenium, and B vitamins all play roles in normal skin and hair function. I know, it sounds boring, but it's true.

Again, how do you get all those amazing nutrients into you... You have to eat well. A heavily processed diet may be worth looking at when you're trying to identify your personal scalp triggers. Really, just read this blog where we detail the principles of building healthy skin (which includes scalp) from the inside out. That way I don't repeat myself too much here.

You may think, well I can just down a bunch of supplements to make up for my lame diet. Mmm, not exactly. Remember, they are called supplements because they are meant to supplement your diet, not replace it.

Furthermore, supplements are not always the answer, especially if you take them without knowing whether a certain deficiency exists. In general, it is better to prioritize getting the bulk of your nutrients from rich, whole foods.

Not saying not to take some well studied and recommended by your naturopath or doctor supplements, but there needs to be a mental switch to at least trying to use food to fill up nutrients needs, instead of supplements - it is not possible to outsource health.

I think this is the part a lot of people will not want to do - change their diet. I know, it's very hard to overcome the addictive nature of certain foods and habits we build around it.

I have been there, and frequently have found myself even falling into old patterns of unhealthy eating that I need to reassess for optimal health. What I learned is that if I am not willing to change my diet to address my health issues, then I am, in a way, choosing those very health issues.

I must make different choices to experience different outcomes. Simple, but oh, so very difficult. I know, friend!

Pay Attention to Personal Triggers

This goes without saying, but paying attention to your own triggers or patterns can go a long way.

In my experience, I noticed that when I cut out all gluten, my skin and scalp began to heal. Then, I cut out pasteurized, denatured dairy and noticed my allergies and skin began clearing even more. Patterns!

Start taking note: does your scalp dandruff worsen during seasons when you are eating more highly processed foods or added sugar? Do digestive issues and scalp flare-ups happen at the same time?

Have you noticed changes after increased alcohol consumption, travel, illness, or a major shift in your routine? *side note, if your dandruff is caused by excess yeast, added sugar is not your friend. Sugar feeds yeast!

Start tracking! Again, this helped me so much. Yes, it takes time to observe differences, but it's so worth it. Track your meals, digestion, stress, sleep, scalp products, and even symptoms for several months.

Observing patterns and flares over time as you eliminate or add things one thing at a time are much more useful than randomly removing five food groups at once. You may want to know what exactly may be your trigger.

For me, I just went all in overnight and over the years noticed flares when I would eat certain things. I kind of went at it "backwards", which worked for me because I was in so much discomfort and was willing to change anything necessary for relief.

Stress Can Show Up on the Scalp

Yup, it sure can. Prolonged and chronic stress often impacts your nervous system, immune system, digestive system, and skin... these functions are all constantly communicating.

Interestingly enough, studies have found an association between stressful life events and seborrheic dermatitis (dandruff) flare-ups. So, supporting your nervous system is a part of scalp care!

Do Anti-Dandruff Shampoos Work?

Alright, we're going there. Dandruff shampoos. In short, yes, anti-dandruff shampoos can work. Let's get into this a bit more...

Ingredients like ketoconazole, selenium sulfide, zinc pyrithione, salicylic acid, and other anti-dandruff agents work in different ways. Some help manage the yeast aspect with dandruff, and others loosen excess scale or reduce buildup. But, there's a problem.

Basically, the larger issue with anti-dandruff shampoo is that controlling or temporarily reducing dandruff does not address the cause of the dandruff. Most of the time, they quite literally act as a bandaid.

Keep in mind, some formulas may also be overly drying or irritating for certain scalps, especially when used too frequently. Not to mention some of the toxic ingredients and added fragrance in these shampoos.

Again, a shampoo may temporarily reduce flakes, all while the person may be doing things that actively promote dandruff.

Eating poorly, taking very hot showers, using irritating styling products, sleeping very little, or living under enormous stress. It's a cycle many are in, and I was too. But for me, none of the shampoos actually worked at all.

I get it, during a horrible flare or dandruff season, medicated shampoos can be something that helps you survive... but in our opinion, they should never be treated as the solution for dandruff.

External Factors That May Affect Your Scalp

Your environment and even everyday habits can also disrupt the scalp’s balance.

Cold weather and indoor heating may dry the skin, while sweat, oil, and styling-product residue can sit on the scalp. This won't come as a surprise to those who have dealt with dandruff, but seasonal shifts are commonly reported as a trigger for seborrheic dermatitis.

Other notable potential contributors include:

• Very hot showers
• Over-washing or under-washing
• Hard water
• Aerosol dry-shampoo buildup
• Artificial fragrance
• Harsh detergents
• Hair spray, gels, and styling products
• Leaving sweat on the scalp
• Wearing tight hats for long periods

Hmm, I see a pattern here. The products you use can worsen dandruff for many.

Common Mistakes When Treating Dandruff

One mistake is believing that a “squeaky-clean” scalp is a healthy scalp. Yeah, washing with harsh cleansers may remove oil and buildup, but it also strips the daylights out of the scalp. Similar to over cleansing or using harsh cleansers on face... you damage the barrier of the skin. Same goes for the scalp.

On the other hand, avoiding shampoo for too long can allow oil, dead skin, sweat, and styling-product residue to accumulate quickly. Around here, we typically wash our hair once a week, but we (Chelsea and I) also don't use toxic styling products.

We understand once a week washes may not be the best for everyone, but over washing can definitely contribute to stripping your scalp. The ideal wash schedule will depend on your scalp, hair texture, activity level, and product use.

I notice when I have used product in my hair, like a hairspray or gel, my head gets so incredibly itchy after day two that I have to wash my hair or else I will itch sores into my head.

See, this is where the cycle begins! No issues going a week between washes, sometimes with the health of our Dry Shampoo, when I use no synthetic styling products. I love me some Brow Styling Wax & Clay for my edges.

It never makes my head itch but I can still get that sleek, slick back look I like to wear occasionally.

Another thing to avoid doing is applying excessive amounts of refined and processed oil. Slathering your scalp in coconut oil is often not the best idea for dandruff ridden scalps as it is occlusive.

The correct oil can be a wonderful and supportive tool for a dry, tight , and even irritated scalp, but the type of oil you use matters. More on what we recommend below.

Lastly, many people rush the healing process. Remember when I said it took about a year for my dandruff and plaque psoriasis to completely clear up? Yeah, these things don't clear up overnight.

It took persistent and most of all, consistent diet change and scalp care to achieve a clear scalp. I say it almost every blog - the body will not be rushed.

Creating a Holistic Scalp-Care Routine with SBA

Thorough yet gentle cleansing is the first step. Our Nourish Shampoo Bar helps cleanse the hair and scalp without relying on the harsh detergents found in many conventional shampoos.

Formulated with organic, wild harvested, and specific scalp boosting ingredients, our cured bar will not strip your scalp. Switching to a shampoo bar like ours may result in a short adjustment period - read what to expect here + 2 DIY clarifying rinses.

Follow with our Nourish Conditioner in Minty Garden (or any of our other scents) to help replenish and moisturize not only the scalp, but the hair strands. For an extremely dry, tight, flaky scalp, the conditioner can also be used occasionally as an overnight scalp treatment. We love doing this!

With clean scalp and hair, apply the conditioner directly to the driest areas of the scalp. *Pro Tip: wear a bonnet to protect your pillow! Wash it out thoroughly the following morning.

Now, for one of our most popular dandruff relief products... Our Revitalize Hair & Scalp Serum can also be used as a targeted daytime or pre-wash treatment! Massage a small amount into areas that feel especially dry.

It may be particularly helpful for someone whose scalp is extremely dry and irritated as it has an extremely soothing cooling effect on the scalp.

A little goes a long way! Start with a pump and massage into the scalp. Use more if needed.

We also crafted the multi-shade, aerosol-free, non-toxic Refresh Dry Shampoo to help you go longer between washes while absorbing excess oil and boosting volume without visible residue. 

Why We Chose These Oils for Revitalize Hair & Scalp Serum

We intentionally created the formula with oils that help soften, condition, and support a dry scalp without relying on an overly heavy, greasy base. Lightweight oils such as jojoba, argan, and marula help restore the scalp’s natural lipid barrier, especially after washing, without leaving the scalp feeling smothered.

This is especially important for dandruff-prone scalps. While rich oils can be helpful for dryness, applying too much of a thick or highly coating oil may trap sweat, dead skin, and product residue against the scalp. We want the scalp to breathe... not to suffocate under heavy oils that can contribute to buildup!

Our goal is not to completely coat the scalp. It is to provide concentrated support with a small amount of thoughtfully selected, high quality supportive oils. A few drops can help soften dry patches, reduce that tight, stinging feeling, and support a healthier scalp base without suffocating your scalp.

The goal is to create a clean, nourished, optimal environment that the scalp’s natural barrier can function well and not fight against the products being placed onto it.

Supporting the Scalp as a Whole

As we have discussed in this blog, dandruff is usually not a surface-level issue, and your scalp should not be treated like it exists separately from the rest of your body. Diet, gut health, stress, environment, product buildup, and the way you care for your scalp all play a role.

The goal is not perfection or an overnight fix, because those are impossible. The goal here is realistic consistency. Support your body from the inside out, simplify your routine, pay attention to your personal triggers, and choose products that nourish rather than inflame the scalp.

My own scalp improved dramatically over time, and consistent care can help you better understand what supports yours.
