What Causes & How to Stop Dandruff - Restore Scalp Health

Everything out there is always how to get rid of dandruff, nothing really about the cause. I'll give you a Guide on how to not get it, if you have it today, then how to get rid of it, not manage it, how to get rid of it and not have it happen again. The primary cause of dandruff is often attributed to an overgrowth of a naturally occurring yeast called Malassezia. This yeast lives on the scalp but can proliferate under certain conditions, leading to increased skin cell turnover, which causes flakes to form. A dry scalp can also contribute to dandruff. When the scalp becomes dry, it produces flaky skin cells that shed from the scalp, mimicking the appearance of dandruff. On the other hand, excessive oil production on the scalp can also cause flakes. This can result in scalp irritation, clogged pores, and an overgrowth of Malassezia, leading to dandruff.

I think it's possibly candida, fungus in the blood, a pH imbalance or hormonal imbalances, then unfortunately iy could even be something as awful as parasites. Then there's conditions such as eczema, psoriasis, or seborrheic dermatitis can also cause dandruff-like symptoms. These conditions lead to inflamed, flaky, and irritated skin on the scalp. Poor nutrition, stress, lack of sleep, and environmental factors like harsh weather can contribute to dandruff development or worsen the condition, whatever it is, it is not caused by a lack of cleanliness. I'm going to just get into the remedies that work by targeting the underlying causes, such as Malassezia overgrowth, inflammation, dryness, and imbalanced scalp conditions. If you do have eczema currently I do recommend you read the Eczema – The Natural Path Out Guide here. For now lets just get this issue cleared up so you can get on with your life. I'll explain why the following topical things work, then foods, supplements and other hacks, Then I'll show how to combine the topicals to use them for the most effective result.

The Topicals & Why they Work

Diatomaceous Earth: DE can exfoliate the skin, absorb toxins, kill parasites and promote a healthy scalp. The fine, abrasive texture of DE helps to gently scrub away the skin’s outer layer without causing irritation. Diatomaceous Earth helps absorb excess oil, promoting a cleaner scalp and preventing fungal overgrowth. It has absorbent properties, which means it can help to draw out toxins, impurities, and excess oils from the scalp. By detoxifying the scalp, DE may help reduce inflammation and irritation, which are often linked to dandruff. It also contains silica, which has natural anti-fungal properties. This can help inhibit the growth of Malassezia, the fungus responsible for dandruff, by creating a less hospitable environment on the scalp.

Oregano Essential Oil: Oregano essential oil contains carvacrol and thymol, two potent antifungal compounds that help inhibit the growth of dandruff-causing fungi. The antimicrobial nature of Oregano Oil helps keep the scalp clean and free from bacteria that may contribute to dandruff, scalp infections, and irritation. This makes it an excellent alternative to synthetic anti-dandruff treatments that rely on chemical preservatives and antimicrobial agents. Oregano oil contains rosmarinic acid, which has strong anti-inflammatory effects that help soothe the scalp and reduce itchiness, redness, and discomfort. It I is sebum balancing, excessive oil production can worsen dandruff by creating an environment in which yeast thrives. Oregano oil regulates sebum production, ensuring that the scalp isn’t too dry or too oily, helping to restore balance and prevent flare-ups. It also supports scalp detoxification, helping remove toxins and impurities that contribute to dandruff and scalp irritation.

Apple Cider Vinegar: ACV offers several key benefits that can help alleviate dandruff symptoms. Its natural acidity, antimicrobial properties, and ability to restore balance to the scalp all play a role in its effectiveness. The scalp, like the rest of the skin, has an acidic pH that is essential for maintaining its health. The natural pH of the scalp is slightly acidic, typically around 4.5 to 5.5. However, many shampoos, hair products, and environmental factors can alter the pH balance of the scalp, making it more alkaline. An alkaline scalp is an inviting environment for fungi, including Malassezia, which thrives in these conditions. ACV is highly acidic with a pH of around 2-3. When applied to the scalp, it helps to restore the natural acidic pH of the skin. By rebalancing the pH, ACV creates an environment that is less favourable for fungal overgrowth, effectively preventing and reducing dandruff. A study published in the International Journal of Dermatology showed that restoring the pH balance of the scalp can help reduce dandruff, inflammation, and fungal infections, which are all common contributors to the condition. ACV contains acetic acid, which is known for its antifungal and antimicrobial properties. Malassezia, the yeast that causes dandruff, is particularly susceptible to the antifungal effects of acetic acid.

The acetic acid in ACV is effective in controlling fungal overgrowth on the skin. It disrupts the cell membranes of fungi, making it difficult for the organisms to survive and proliferate. It helps remove dead skin cells and other debris from the scalp, preventing the buildup of flakes that contribute to dandruff. This gentle exfoliation helps reduce the appearance of dandruff while maintaining a healthy scalp. A clinical trial published in Dermatitis indicated that ACV's exfoliating properties can help in the management of scalp conditions by promoting the shedding of dead skin cells without irritating the scalp. The anti-inflammatory properties can help soothe the scalp, reduce redness, and relieve the itchiness that often accompanies dandruff. Its anti-inflammatory effect comes from the acetic acid and other organic compounds present in the vinegar, which can calm irritated skin. In a study conducted by the American Journal of Clinical Dermatology, ACV’s acetic acid was shown to reduce skin irritation and promote faster healing of damaged skin, thus helping with scalp conditions like dandruff. It helps cleanse the scalp by removing product buildup, excess oils, and environmental pollutants that can contribute to dandruff. It also detoxifies the skin by promoting the removal of impurities from the scalp, preventing clogged pores that can lead to irritation or dandruff.

Borax: Borax is a naturally occurring mineral compound with powerful antifungal, antibacterial, and cleansing properties. It has been used for centuries as a remedy for various skin and scalp conditions, including dandruff. Borax is a potent antifungal agent that disrupts the fungus’s ability to grow and spread, reducing flaking and irritation. Borax gently cleanses the scalp without damaging its natural oil balance, making it suitable for dry and sensitive skin types. It has mild alkalinity, which helps neutralise excess acidity on the scalp and restore its natural balance. Borax acts as a natural detoxifier, breaking down these residues and leaving your scalp fresh and clean. Don't use Borax Substitute which is everywhere, it is not pure Borax.Pure Borax is sodium tetraborate decahydrate — a naturally occurring mineral composed of sodium, boron, oxygen, and water.

Coconut Oil: Rich in antifungal, antibacterial, and deeply moisturising properties, coconut oil not only combats dandruff at its root but also nourishes and restores the health of your scalp and hair. In this article, we’ll explore how coconut oil works against dandruff and provide step-by-step methods to use it effectively. It's packed with medium-chain fatty acids, antioxidants, and essential nutrients that make it a powerful scalp treatment. Coconut Oil contains caprylic acid and lauric acid, two potent antifungal agents that help combat fungal overgrowth and prevent dandruff from returning. It is a deep-penetrating moisturiser that hydrates the scalp, prevents excessive dryness, and restores balance to the scalp’s natural oil production. Coconut oil’s natural anti-inflammatory compounds help soothe an irritated scalp, reducing itching and discomfort. It's naturally antibacterial, which means it can help prevent scalp infections that may worsen dandruff symptoms. It also gently removes dirt, excess oil, and product buildup, keeping the scalp clean and healthy. Coconut oil strengthens the hair, reduces protein loss, and helps protect against damage from environmental stressors. This is the base of the topicals, most other things will be added to it.

Hydrogen Peroxide: Hydrogen peroxide is a potent antifungal and antibacterial agent, helping to eliminate these unwanted microorganisms and restore scalp health. It acts as a natural exfoliant, breaking down dead skin cells, oil, and product residue that contribute to dandruff. This gentle exfoliation prevents the accumulation of flakes and keeps the scalp clean. When applied to the scalp, hydrogen peroxide releases oxygen molecules, which can help improve blood circulation and promote healthier skin cell regeneration. This can reduce scalp irritation and inflammation over time. Hydrogen peroxide removes excess oil without overly drying the scalp, making it an excellent remedy for oily dandruff. It has anti-inflammatory properties, helping to soothe irritation and calm the scalp. Use with caution, to keep my solutions section simple, I don't include this, but it really works also, I just think there are more gentle options. For those with a sensitive scalp, adding aloe vera to hydrogen peroxide can reduce irritation and provide deep hydration.

Tea Tree Oil: Tea Tree Oil has long been revered for its potent antifungal, antibacterial, and anti-inflammatory properties, making it an effective natural remedy for dandruff. The flakes and itching associated with dandruff are often linked to an overgrowth of the yeast Malassezia, which tea tree oil helps to combat directly. When applied to the scalp—usually diluted with a carrier oil like coconut or jojoba—tea tree oil works to soothe irritation, reduce flaking, and restore microbial balance. It also helps unclog hair follicles and nourish the scalp, creating an environment less prone to dandruff reoccurrence. Regular use of tea tree oil in your scalp care routine can reduce itching, minimise visible flakes, and support overall scalp health—naturally and without harsh chemicals. I'm listing it as it's effective but it is not in the regime as there is too much already I feel the others are enough. But you can totally use it and get results.

Witch Hazel: Witch hazel is a natural astringent with anti-inflammatory properties, making it ideal for treating dandruff caused by scalp inflammation or irritation. Witch hazel can help reduce itching and swelling, while its antifungal and antioxidantproperties assist in soothing the scalp and eliminating flakes. Research published in the Journal of Drugs in Dermatology suggests that witch hazel can be useful in managing conditions like dandruff due to its anti-inflammatory and soothing properties. If you want to try it, soak a cotton ball in witch hazel extract and apply it to your scalp. Let it sit for 15-20 minutes before rinsing.

Foods & Supplements

I'm going to include meat eater and vegetarian food options followed by the supplement option. Than specific internal supplements that work and oils for internal nourishment. The following section on water and teas, at the end of that I've listed a short few things to avoid.

Omega 3 & 6

Omega-3 fatty acids reduce inflammation, keeping the scalp hydrated and preventing excessive dryness. A lack of Omega-3s can lead to dry skin, flaking, and increased scalp irritation.

Eat: Fatty fish (salmon, mackerel, sardines) Chia seeds, Walnuts, Hemp Seeds.

Supplement: Krill Oil is best or take the vegan omegas we have.

Zinc

Zinc regulates sebum production on the scalp and has natural antifungal properties, helping to control the overgrowth of Malassezia, the fungus linked to dandruff.

Eat: Organic Meat, Oysters, Pumpkin Seeds, Chickpeas, Cashews.

Supplement: Take a Zinc tablet daily, if long term use Zinc & Copper.

B Vitamins

B vitamins, particularly B7 (biotin), B6, and B12, play a crucial role in cell renewal and healthy hair growth. A deficiency can contribute to scalp dryness and flaking.

Eat: Beef Liver, Cod Liver Oil, Sweet Potatoes, Carrots.

Supplement: Liposomal Vitamin A is best.

Probiotics

An imbalance of gut bacteria can lead to increased yeast and fungal overgrowth in the body, contributing to dandruff. Probiotic-rich foods help restore gut balance and, in turn, promote a healthier scalp.

Eat: Raw Milk, Raw Unpasteurised cheese, Sauerkraut, Kimchi, Fermented Meats (Salami, Sucuk, Some Dry-Cured Sausages - Traditional methods (without preservatives) Kefir, Yoghurt (unsweetened), Miso, Natto.

Supplement: Take a Probiotic daily for a few weeks, break and repeat occasionally or as needed.

Other Recommended Foods

Coconut Oil: Internally it helps balance scalp hydration from within.

Coriander & Parsley: Rich in chlorophyll, which detoxifies the body and reduces the internal toxins that contribute to dandruff.

Turmeric: Potent anti-inflammatory that helps soothe an irritated scalp and reduce dandruff-related redness.

Beetroot: This just seems to work for some people, eating a little daily.

Other Supplements - Internal

Oregano Essential Oil: Oregano Oil contains powerful compounds, notably carvacrol and thymol, which are well-documented for their antifungal, antibacterial, and anti-inflammatory properties. When dandruff is caused or aggravated by an overgrowth of malassezia or internal candida imbalance, oregano oil can help systemically reduce fungal load and restore microbial harmony. Carvacrol, the star compound in oregano oil, has been shown in studies to disrupt fungal cell membranes, especially Candida and Malassezia. It also supports the reduction of biofilms, which are protective barriers created by microbes that make them harder to eliminate. Oregano oil also works against gram-positive and gram-negative bacteria, helping to clean up low-grade infections that could affect the scalp through the gut-skin axis.

How to Take It: Take a 10,000iu Softgel a few days a week best taken at night in my opinion.

Digestive Enzymes: Improper digestion, especially of fats and proteins, can lead to nutrient deficiencies and toxic build-up, which manifests on the skin. Poor digestion is linked to dermatological symptoms, particularly in the scalp and face. Using Digestive Enzymes enhances nutrient absorption, reduces toxic burden, and supports liver function. Enzyme supplementation supports more efficient internal processing and elimination.

How to Take It: Take 1 capsule before a meal daily, cycle.

Black Seed Oil: Derived from the seeds of Nigella sativa, BSO has been used for thousands of years across the Middle East, North Africa, and South Asia. Black Seed Oil contains thymoquinone, a compound with potent anti-fungal and antibacterial properties. It targets the yeast-like fungus commonly responsible for dandruff. Thymoquinone is also immunomodulatory, helping to calm systemic inflammation that can affect the skin barrier. Black Seed Oil has mild hepatoprotective effects and supports microbial balance.

How to Take It: Begin with ½ teaspoon to 1 teaspoon daily, taken on an empty stomach or before meals. For deeper healing, consider a 3–4 week course, pausing for a few days between cycles.

Triphala: Also known "Three Fruits," is a revered blend in Ayurveda composed of Amalaki (Emblica officinalis), Bibhitaki (Terminalia bellirica), and Haritaki (Terminalia chebula). Traditionally used to support digestion, detoxification, and rejuvenation, Triphala is now gaining modern recognition for its cleansing effects on the skin and scalp through the gut. Triphala acts as a mild colon cleanser, encouraging regular elimination and reducing toxic build-up, which can otherwise manifest through the skin, including the scalp. By reducing bloating, sluggish digestion, and Candida overgrowth, Triphala supports a healthier internal terrain, decreasing the systemic inflammation that can worsen dandruff. The three fruits are rich in vitamin C and polyphenols, aiding in cellular regeneration, collagen production, and reducing oxidative stress — all beneficial for scalp and hair health.

How to Take It: Take 1–2 grams of Triphala powder with warm water, preferably before bed. Alternatively, steep Triphala powder in hot water to create a digestive tea. Use consistently for 6–8 weeks for best results, cycling with breaks to avoid dependency.

Water & Teas

Water is the foundation of a healthy scalp. While many focus on topical treatments and supplements for scalp issues like dandruff or irritation, the hydration and quality of your internal environment plays a critical role. Your scalp is skin, and like all skin, it reflects what's happening inside the body. The skin, the scalp relies on sufficient internal hydration to maintain its protective barrier, regulate oil production, and support cell turnover. Dehydration can result in flaky, dry, tight-feeling scalp Excess sebum as a compensatory mechanism (leading to greasy dandruff) Reduced detoxification of waste via lymph, skin, and kidneys. It also means poor nutrient delivery to hair follicles.

Drinking adequate water ensures the epidermis retains moisture, the dermis receives nutrients, and inflammation is kept in check. It flushes internal toxins that could otherwise manifest through skin eruptions or irritation. It improves circulation, which supports scalp oxygenation and nutrient delivery. It regulates sebaceous glands, balancing oil production. It supports lymphatic flow, clearing inflammation-causing waste. It also enhances digestion and elimination, reducing systemic toxicity. I'll go into the Shower Filter later to avoid the contaminants from bad water on the scalp. But as for drinking it, keep it simple. The water I drink is first gravity filtered, then structured. I don’t mention these systems because we happen to sell them — rather, we choose to offer them because I genuinely believe they’re the finest options for everyday use. The gravity filter effectively purifies the water, removing contaminants, while the Sacred Geometry Carafe revitalises it, restructuring the water crystals and restoring its natural, vibrant state. It becomes, quite simply, living water once more. Distilled Water short term is a great detox, just not to be your day to day water, some say it is, you research, you decide, I like to use it now and then.

Pau d’Arco (Inner Bark): This Amazonian traditional medicine is a potent anti-fungal and immune-modulating herb, Pau d’Arco targets systemic yeast overgrowths like Candida and potentially Malassezia when taken internally.

How to Take It: Drink the tea for up to 3 weeks, then a week off, repeat if needed.

Chaga Mushroom: The King of Medicinal Mushrooms a favourite at Ancient Purity this Siberian and Nordic folk powerhouse is a powerful adaptogen and anti-inflammatory, Chaga supports the immune system, calms oxidative stress, and is rich in betulinic acid, which has antimicrobial properties. I think it is a tea to consider during this journey.

How to Take It: Drink Chaga tea as desired, always take breaks from all medicines.

Foods & Drink to Avoid for a Healthy Scalp

Certain foods can worsen dandruff by increasing inflammation, disrupting gut health, and encouraging fungal overgrowth.

Processed Sugar & Refined Carbs: Excess sugar feeds yeast (Malassezia), worsening dandruff symptoms.

Dairy Products: I know I recommended Raw Milk for probiotics, but standard dairy and for some individuals all dairy increases mucus production and inflammation, contributing to an oily, flaky scalp.

Alcohol & Caffeine: Both alcohol and caffeine dehydrate the scalp and disrupt gut bacteria, increasing the likelihood of dandruff.

Hair & Scalp Care

Natural Shampoo - Free from SLS and Harmful Additives

The shampoo you choose can either soothe or sabotage your scalp. Most commercial shampoos are loaded with Sodium Lauryl Sulphate (SLS) and other synthetic detergents, preservatives, and fragrances — ingredients that strip the scalp of natural oils, irritate the skin barrier, and worsen flaking and inflammation. A natural shampoo, free from SLS, parabens, silicones, and synthetic fragrances, is gentle yet effective. Instead of foam and fragrance, it offers plant-based cleansing agents, botanical extracts, and essential oils that clean without disruption. Over time, it helps to rebalance sebum production and support the scalp’s microbiome — crucial for keeping dandruff-causing yeast like Malassezia in check. When making the switch to a natural shampoo, some may go through a short transition period as the scalp adjusts to its new, healthier environment. But within weeks, most notice softer hair, reduced itching, and a calmer, flake-free scalp. Find natural shampoos and conditioners in out Hair Health section.

Shower Filters – Removing Chlorine and Fluoride for Scalp Clarity

Even the purest shampoo can’t compete with what’s hidden in your shower water. Most tap water in the UK is treated with chlorine, and in some areas, fluoride. While essential for municipal hygiene, these chemicals are harsh on the skin — and especially damaging to the delicate microbiome and oils of the scalp. Chlorine strips natural oils, dries the skin, and can disrupt the bacterial balance that keeps the scalp resilient. Fluoride, although more debated, has been linked anecdotally to increased dryness and irritation. A quality shower filter removes these substances along with other contaminants like heavy metals, volatile organic compounds, and even microplastics. By filtering your shower water, you bathe your scalp in clean, chemical-free water. This single change often brings immediate improvements for those with itchy or reactive scalps. Hair feels softer, the scalp is calmer, and natural moisture levels are better preserved. We have a great Shower Filter at Ancient Purity.

Natural Bristle Brushing – Daily Stimulation for Scalp Vitality

Beyond what we cleanse with, how we treat the scalp physically matters too. The act of brushing the hair with a natural bristle brush such as one made from boar bristles is an age-old practice that offers surprising benefits. A natural bristle brush distributes sebum (your scalp’s own conditioning oil) from the roots to the tips, protecting the hair while naturally moisturising the scalp. Brushing also stimulates circulation, bringing blood flow and nutrients to the follicles, encouraging healthy skin turnover and less flaking. Unlike plastic brushes, which can tug and damage, boar bristle brushes glide through the hair and gently massage the scalp. Just a few minutes once or twice daily can have a noticeable effect, leaving the scalp more balanced, less prone to build-up, and encouraging stronger, glossier hair.

Scalp Massage: A Natural Therapy for Dandruff & Scalp Vitality

In the pursuit of a flake-free, vibrant scalp, we often focus on what we apply — shampoos, oils, or treatments — yet we can overlook one of the most ancient and effective methods of scalp care: massage. Practised for centuries across cultures, self head massage and regular scalp massage are not just relaxing — they are profoundly therapeutic, especially when it comes to dandruff and overall scalp health. The scalp, like any part of the body, needs circulation, stimulation, and touch. When blood flow is poor, cellular turnover slows, and the skin becomes more prone to dryness, flaking, and imbalance. Dandruff can take hold in stagnant, neglected tissue. But when you introduce daily or weekly scalp massage, you increase microcirculation, encouraging oxygen, nutrients, and immune cells to flood the area. This nourishes the follicles and skin, supporting natural oil production, removing built-up dead skin, and helping the scalp regulate itself. It’s particularly effective for dry, flaky dandruff, where stimulating sebum production and improving hydration can bring noticeable improvement. Massage is also known to support the body’s lymphatic drainage, helping to clear toxins and inflammation from local tissues. For the scalp, this means clearing out blocked follicles, reducing puffiness, and making the environment far less hospitable for yeast or fungal overgrowths, such as the common Malassezia species often linked to dandruff. When done consistently, massage acts almost like a gentle detox — encouraging natural exfoliation, breaking up hardened sebum plugs, and retraining the scalp to function optimally. Combine the massage when you apply the topicals, it is extra enhancing.

Creating the Topicals

So I may come back here soon with my own creation for a Scalp Tonic but for now I'll suggest you make 2 different topicals to have variation to see what really works, one or both. The Diatomaceous Earth is used alone

Scalp Cleanse Blend

This method helps balance the pH of the scalp, eliminate excess yeast, and remove dead skin cells. Use this rinse 1-2 times a week, or as needed depending on the severity of your dandruff. Leave it on for 30 minutes to 1 hour.

• 3 tablespoons of warmed Coconut Oil.
• 1 tablespoon of ACV
• 3 drops of Oregano Essential oil

Applying

• Wash your hair first.
• Pour the solution over your scalp.
• Massage in gently for 1-2 minutes.
• Leave on your scalp for 5-10 minutes.
• Rinse thoroughly with cold water.

Diatomaceous Earth Application

This is used Topically alone and dry, yes dry, no mixing. Use this treatment once a week or as needed based on the severity of your dandruff.

• Wash your hair with a gentle, toxin free shampoo
• Dry your hair.
• Apply 1-2 teaspoons of DE.
• You can use your fingers or a brush to distribute the powder evenly.
• Gently massage the DE into your scalp for about 3-5 minutes.
• Allow it to sit on your scalp for 15-30 minutes.
• Rinse your scalp thoroughly with lukewarm water.
• You can follow up with a mild natural conditioner to keep your hair hydrated.

The Borax Blend

Use this one just once a week, you may respond better to one than the other. You'll need pure food-grade borax, free from contaminants. Do not do more than 2-3 applications per week of both together, so each of these topical treatments you can only do 3 applications combined, 1 of one 1of the other, 1 of the other or 2 of 1 one of the other etc. Always rinse your hair thoroughly after using borax to prevent any residue buildup.

• 1 tablespoon of Borax.
• 2 cups of warm water.
• 1 tablespoon of Coconut Oil.

How to Apply:

Dissolve borax in warm water and mix in melted coconut Oil.
Apply to the scalp, focusing on flaky or dry areas.
Leave it on for 20-30 minutes, then rinse thoroughly with lukewarm water.

Heal

Finally, beyond all the tangible practices and remedies, don’t underestimate the power of the mind in healing. Take a few moments each day to simply breathe deeply, breathe into your scalp and hair, it doesn't make sense yet you know exactly what I mean. As you inhale, feel your breathing life and vitality into your scalp, this is nourishing the roots and strengthening the hair. Visualise your scalp restoring balance and your hair becoming fuller, heavier, and more vibrant with every breath. Never identifying with ailments, dandruff was simply a condition passing through, perhaps a little lesson in awareness. Mind over matter is a real force in healing. By aligning your thoughts with regeneration and health, you support every other step you’re taking. Let your intention be as powerful as the products and practices you use.

Forget the word of this issue you had now and restore your health to 100%. I hope my Guide gives you freedom over that issue and you live with a healthy scalp, now go forth and enjoy yourself, share this with others, if this has helped you I'd really appreciate a review on Google, you just need a gmail or YouTube account. Or just tell people about us, what we do and what they can find in these Guides. Be well and Blessed Be, Tom
