If you have been dealing with white flakes on your shoulders or an itchy scalp that just will not settle, you are not alone. Dandruff is one of the most common scalp conditions in the world, affecting nearly half of all adults at some point. The good news is that once you understand what is actually causing it, knowing how to remove dandruff becomes much more straightforward. During your consultation, your dermatologist may also perform Trichoscopy, a non-invasive scalp examination that helps identify the underlying cause of dandruff and guides a more targeted and effective treatment plan.
This guide covers everything from the reasons for dandruff and types of dandruff to the best medicated shampoos, home remedies, and professional anti dandruff treatment available at Modern Aestheticss Dubai.
What Is Dandruff?
Dandruff is a chronic, non-contagious scalp condition in which skin cells shed at a faster rate than normal, producing visible white or yellowish flakes. These flakes are simply dead skin cells clumping together with scalp oil before falling off. The scalp also becomes itchy and, in more severe cases, red and irritated.
It is important to distinguish dandruff from a dry scalp. Dry scalp produces small, white, dry flakes and is triggered by a lack of moisture. Dandruff, on the other hand, is often linked to excess oil and a naturally occurring fungus called Malassezia, which produces larger, oilier flakes. Identifying the root cause is essential because the right treatment depends on the condition. In some cases, untreated scalp issues may contribute to skin concerns such as Acne on Cheeks, particularly when excess oil and flakes come into contact with the facial skin.
Quick fact: Dandruff is not caused by poor hygiene. It is a scalp skin condition with biological and environmental triggers. Anyone can develop it regardless of how often they wash their hair.
What Causes Dandruff?
Understanding the reasons for dandruff is the first step toward treating it effectively. The internal causes of dandruff are often biological, while external triggers relate to lifestyle, environment, and hair care habits.
Biological and Internal Causes
Malassezia Fungus
A yeast-like microorganism that lives naturally on most adult scalps. It feeds on sebum and produces oleic acid, which roughly half the population is sensitive to. This sensitivity triggers rapid cell shedding and visible flaking.
Seborrheic Dermatitis
Overactive sebaceous glands produce excess oil, creating the ideal environment for Malassezia to thrive. This produces larger, yellowish, greasy flakes and is one of the most common reasons for dandruff in both men and women.
Dry Scalp
A lack of moisture impairs the scalp’s skin barrier. This produces small, dry, white flakes with no associated oiliness. Cold weather and harsh shampoos are frequent triggers.
Lifestyle and Environmental Triggers
Several lifestyle factors are also well-established reasons for dandruff:
- Infrequent washing: Allowing oils, sweat, and dead skin to accumulate on the scalp worsens flaking over time.
- Over-washing or very hot showers: This strips the scalp of protective natural oils, prompting defensive dryness and flaking.
- Product sensitivity: Alcohol-based gels, strong fragrances, and harsh hair dyes can irritate the scalp and trigger rapid cell shedding (contact dermatitis).
- Stress: Chronic stress weakens the immune system and compromises the scalp’s skin barrier, making flare-ups more frequent and harder to control.
- Hormones and age: Dandruff often begins around puberty when hormone-driven oil production spikes. Reasons for dandruff in men include a generally higher sebum production, making them statistically more prone to it.
- Weather changes: Cold, dry air strips scalp moisture in winter. Hot, humid weather increases sweat and oil production in summer. Both can aggravate dandruff.
Which vitamin deficiency causes dandruff? Deficiencies in zinc, B vitamins (particularly B2, B3, and B6), and healthy fatty acids (omega-3) can weaken the scalp’s skin integrity, making it more prone to flaking and inflammation. Addressing these through diet or supplementation supports the scalp alongside topical treatment.
What foods trigger dandruff? A diet high in refined sugars and processed carbohydrates can promote yeast overgrowth, potentially worsening Malassezia-related dandruff. Excess saturated fats may also increase sebum production. On the supportive side, foods rich in zinc (pumpkin seeds, legumes), omega-3 (oily fish, walnuts), and B vitamins (eggs, leafy greens) help maintain a healthy scalp barrier.
Types of Dandruff
Identifying which of the main types of dandruff you have helps you choose the right shampoo for dandruff and the right course of action.
Dry Scalp Dandruff
Small, white, powdery flakes that fall easily from the scalp. The scalp itself feels tight and itchy. Common in winter and in people who wash their hair too frequently or use harsh shampoos. Best managed with a gentle, moisturising anti dandruff shampoo and lukewarm water.
Oily Scalp Dandruff (Seborrheic Dermatitis)
Larger, yellowish flakes that tend to stick to the hair and scalp. The scalp may look shiny, red, or irritated. This is the most common form seen in adults. What causes dry dandruff and oily dandruff are different mechanisms, and treating oily dandruff requires antifungal ingredients like ketoconazole or selenium sulfide.
Fungal Dandruff
Caused by an overgrowth of the Malassezia fungus. Flakes are typically irregular in shape and accompanied by persistent itching. This type responds well to antifungal shampoos used consistently. In persistent cases, a dermatologist may prescribe topical antifungal medication.
Disease-Related Dandruff
Scalp psoriasis and eczema both produce flaking that is often mistaken for standard dandruff. Psoriasis produces thick, silvery scales and may extend beyond the hairline. Eczema produces red, dry, intensely itchy patches. Both require a clinical assessment and a tailored treatment plan rather than off-the-shelf products.
Does Dandruff Cause Hair Loss?
This is one of the most common questions people have: can dandruff cause baldness? The short answer is that dandruff itself does not directly cause permanent hair loss. However, there is an indirect relationship that is worth understanding.
Persistent scalp inflammation from severe or untreated dandruff can weaken the hair follicle environment over time. Constant scratching also damages the follicles and can cause temporary hair shedding. When the underlying dandruff and scalp inflammation are properly treated, hair shedding typically stops.
If you are noticing significant hair loss alongside dandruff, it is worth having both evaluated together. Conditions such as seborrheic dermatitis and scalp psoriasis, which can look like dandruff, are known to affect hair density when left unmanaged for long periods. At Modern Aestheticss, scalp health assessments are available as part of a broader hair treatment consultation.
How to Remove Dandruff: Step-by-Step
Learning how to remove dandruff effectively requires both the right products and the right habits. Here is a practical, dermatologist-aligned approach to how to easily get rid of dandruff at home.
Use a medicated anti dandruff shampoo
Apply two to three times a week. Massage it into the scalp and leave it for five minutes before rinsing. Rotation between different active ingredients prevents resistance over time.
Wash with lukewarm water only
Hot water strips the scalp’s natural protective oils, worsening both dryness and oiliness as a reactive response. Rinse thoroughly with cool or lukewarm water after shampooing.
Adjust washing frequency to your scalp type
Oily scalp: wash more frequently to clear sebum and dead skin buildup. Dry scalp: wash less often and use a gentle, hydrating shampoo for dandruff to avoid over-stripping.
Reduce heavy styling products
Gels, waxes, mousses, and dry shampoos build up on the scalp and clog follicles, which exacerbates flaking. Minimise use and wash the scalp thoroughly when you do use them.
Support with scalp-nourishing habits
- Brush gently before washing to loosen flakes and distribute scalp oils.
- Manage stress through consistent sleep, exercise, and relaxation practices.
- Eat a diet rich in zinc, B vitamins, and omega-3 fatty acids.
- Protect the scalp from direct sun in UAE summer with hats or SPF spray.
Consult a dermatologist if it persists
If dandruff has not improved after two to three weeks of consistent OTC treatment, a dermatologist can assess whether an underlying condition like seborrheic dermatitis or scalp psoriasis is the cause and prescribe stronger anti dandruff treatment accordingly.
Choosing the Best Dandruff Shampoo
The best anti dandruff shampoo for you depends on which type of dandruff you have. Different active ingredients target different underlying mechanisms. Here is how to read the label and match the ingredient to the cause.
Anti dandruff shampoo for men: Men tend to have higher sebum production, which makes antifungal formulations with ketoconazole or selenium sulfide the most effective choice. The best shampoo for dandruff in men prone to oiliness should be used two to three times a week and left on the scalp for several minutes before rinsing.
Whichever product you choose, the best dandruff shampoo is one you use consistently and correctly. Rinsing it off immediately reduces efficacy. Leaving it on the scalp for five minutes gives the active ingredient time to work.
Dandruff Home Remedies
Several natural approaches can complement your main dandruff treatment at home, especially for managing itching, soothing the scalp, and reducing flare-ups between wash days. These dandruff home remedies work best alongside medicated shampoos rather than as a standalone solution for persistent dandruff.
Tea Tree Oil
- Has antimicrobial and antifungal properties
- Mix 2 to 3 drops into a carrier oil such as jojoba or coconut oil
- Massage into the scalp 30 minutes before washing
- Do not apply undiluted as it can irritate the scalp
Apple Cider Vinegar (ACV)
- Helps balance the scalp’s pH environment
- Mix equal parts ACV and water in a spray bottle
- Apply to the scalp after shampooing, leave for 15 minutes, rinse
- Use once a week rather than daily
Aloe Vera Gel
- Reduces scalp inflammation and soothes itching
- Apply fresh aloe gel directly to the scalp
- Leave for 20 to 30 minutes before rinsing
- Suitable for sensitive and dry scalp types
Neem Oil
- Has strong antifungal and antibacterial properties
- Dilute in a carrier oil before applying to the scalp
- Particularly effective for fungal dandruff
- Wash out thoroughly after 30 to 45 minutes
If you are looking for how to naturally cure dandruff, these remedies offer genuine scalp support. However, for persistent or severe dandruff, they are most effective when used alongside a clinically active anti dandruff shampoo rather than in place of one.
How to Avoid Dandruff in the UAE
The UAE climate creates specific challenges for scalp health. Intense summer heat and humidity increase sweat and sebum production on the scalp, while indoor air conditioning rapidly dehydrates the skin and scalp. This combination is a common and often overlooked reason why many people in Dubai experience dandruff that fluctuates throughout the year.
Manage Sweat and Sebum in Summer
Wash hair more frequently during the summer months to remove excess sweat and oil buildup from the scalp. Choose a lightweight antifungal anti dandruff shampoo suitable for daily or near-daily use.
Counter the Effects of Air Conditioning
Air-conditioned environments strip moisture from the scalp. Use a nourishing scalp serum or light hair oil on the lengths to compensate, and stay well hydrated throughout the day.
Protect the Scalp from Direct Sun
UV exposure inflames the scalp and disrupts its barrier function. Wear a hat or use an SPF scalp spray when outdoors during peak hours, particularly in summer.
Choose Products Suited to the Climate
Heavy conditioners and oil treatments can quickly become too rich in a hot, humid environment. Opt for lighter, water-based scalp products in summer and save richer formulations for winter months.
Professional Anti Dandruff Treatment at Modern Aestheticss
For dandruff that does not respond to over-the-counter treatment, or for scalp conditions that require an accurate diagnosis, a professional assessment at Modern Aestheticss in Dubai provides a structured and clinically-led path to resolution. Our dermatologists can distinguish between standard dandruff, seborrheic dermatitis, scalp psoriasis, and other conditions, and prescribe the most appropriate course of anti dandruff treatment.
Scalp Assessment and Diagnosis
A clinical scalp assessment identifies the root cause of dandruff, whether fungal overgrowth, seborrheic dermatitis, psoriasis, or contact dermatitis. Accurate diagnosis means treatment is targeted rather than trial and error, and avoids inadvertently worsening the condition with the wrong products.
Recommended for anyone whose dandruff has persisted beyond four weeks of OTC treatment or is associated with significant redness, scaling, or hair shedding.
Prescription Topical Treatments
Where OTC shampoos have not produced results, prescription-strength antifungal shampoos, topical corticosteroids to reduce inflammation, and combination formulations offer a significantly more potent approach. These are prescribed based on the specific diagnosis and your scalp’s response to prior treatment.
A dermatologist consultation is required before prescription treatments are dispensed.
PRP and Scalp Rejuvenation
For patients where chronic scalp inflammation has contributed to hair thinning or shedding alongside dandruff, PRP (platelet-rich plasma) therapy supports scalp health and follicle recovery. It is delivered as part of a wider hair restoration plan designed around your scalp’s individual condition.

Frequently Asked Questions
What kills dandruff fast? +
The fastest way to reduce dandruff is to use a medicated anti dandruff shampoo containing ketoconazole or selenium sulfide two to three times a week, leaving it on the scalp for five minutes before rinsing. These antifungal ingredients directly target Malassezia, the fungus most commonly responsible for dandruff. For severe cases, a dermatologist can prescribe stronger formulations that work more quickly than OTC options.
How to remove dandruff permanently? +
There is no single permanent cure for dandruff because the underlying factors, including the Malassezia fungus and sebum production, are part of normal scalp biology. However, dandruff can be managed so effectively that it becomes a non-issue in day-to-day life. Consistent use of the right anti dandruff shampoo, appropriate washing habits, scalp-supportive nutrition, and addressing any underlying skin conditions are the closest equivalent to how to cure dandruff permanently.
Why have I got dandruff all of a sudden? +
Sudden dandruff often has a specific trigger. Common causes include a change in season (particularly the shift into winter), a new hair care product causing scalp irritation, increased stress, a hormonal shift, or a recent illness that has temporarily altered the scalp’s microbial balance. Reviewing recent changes in your routine is usually a helpful starting point. If the cause is not obvious and the dandruff is persistent, a scalp consultation can identify it.
Does dandruff cause hair loss? +
Dandruff itself does not directly cause permanent hair loss. However, the scalp inflammation that comes with severe or untreated dandruff can weaken follicles over time. Persistent scratching can also cause temporary shedding. Treating the dandruff and reducing scalp inflammation typically resolves the associated shedding. If hair loss continues after dandruff is under control, a separate hair loss assessment is recommended.
How to avoid dandruff in the UAE? +
The UAE’s combination of extreme heat, high humidity, and air conditioning creates a challenging environment for the scalp. Key measures include washing hair more frequently during summer to control excess sweat and sebum, using a lightweight antifungal shampoo for dandruff, staying hydrated, protecting the scalp from direct sun, and using scalp-nourishing products appropriate to the season. A dermatologist consultation is particularly useful for those whose dandruff worsens cyclically with the UAE’s climate.
Which vitamin deficiency causes dandruff? +
Deficiencies in zinc, B vitamins (particularly B2, B3, and B6), and omega-3 fatty acids are most commonly associated with a weakened scalp skin barrier and increased susceptibility to dandruff. These nutrients support healthy cell turnover, sebum regulation, and skin integrity. A balanced diet rich in whole grains, oily fish, eggs, leafy greens, and legumes addresses the most common nutritional gaps linked to scalp health.
What foods trigger dandruff? +
Refined sugars and simple carbohydrates can promote yeast overgrowth on the scalp, potentially worsening Malassezia-related dandruff. Excess saturated fats may also increase sebum production. Spicy foods and alcohol can trigger scalp inflammation in some people. A balanced, anti-inflammatory diet with sufficient zinc, B vitamins, and omega-3 fatty acids is the most effective dietary approach to supporting scalp health.
What is the difference between dandruff and a dry scalp? +
Dry scalp produces small, white, dry flakes that fall off easily and is caused by a lack of moisture. Dandruff (particularly seborrheic dermatitis) produces larger, yellower, oilier flakes and is linked to excess sebum and fungal overgrowth. The distinction matters because the wrong treatment can worsen the problem. Moisturising treatments help a dry scalp but can worsen oily dandruff. Antifungal shampoos are needed for fungal dandruff but may be too harsh for a genuinely dry scalp.
