Summary
- Dandruff is a common scalp condition causing flaking, itching, and sometimes redness.
- It occurs due to excess oil, yeast overgrowth (Malassezia), or scalp sensitivity.
- Dandruff is often manageable with medical shampoos, antifungal treatments, and professional dermatological care.
- Persistent or severe dandruff may be a sign of seborrhoeic dermatitis, which requires more targeted treatment.
What Is Dandruff?
Dandruff is a common scalp condition characterised by flaking of the skin on the scalp, often accompanied by itchiness.
- Shows up as white or yellow flakes on the scalp and hair
- Can affect the eyebrows, ears, or beard area too
- Not contagious, but it can be persistent without proper treatment
- Ranges from mild flaking through to more chronic seborrhoeic dermatitis
- Needs a proper diagnosis for effective, targeted dandruff removal
What Causes Dandruff?
Dandruff usually develops from a combination of factors rather than a single cause.
- Overgrowth of yeast on the scalp, particularly Malassezia, a yeast that naturally lives on the scalp but can trigger inflammation when it grows out of control
- Excess oil production which creates the ideal environment for that yeast overgrowth to take hold
- Dry scalp or general sensitivity
- Sensitivity to hair products. Harsh shampoos or styling products can irritate the scalp
- Weather changes or stress, both can worsen scalp dryness and flaking
- Underlying skin conditions, such as seborrhoeic dermatitis
Common dandruff triggers include:
- Stress
- Weather changes
- Infrequent washing or product buildup
What Are the Symptoms of Dandruff?
Dandruff can present with a range of scalp symptoms, which may vary depending on the underlying cause and severity. Common signs include:
| Symptom | Description |
|---|---|
| Flaking | White or yellowish flakes on the scalp, hair, and shoulders |
| Itchiness | Varying degrees of scalp itch or irritation |
| Dry or oily scalp | Scalp may feel greasy or tight, depending on the cause |
| Redness / scaling | Common in seborrhoeic dermatitis |
| Sensitivity | Burning or stinging sensation in more severe cases |
What Are the Different Types of Dandruff?
Dandruff can vary depending on its underlying cause and your individual scalp type.
| Type | Description | Treatment Approach |
|---|---|---|
| Dry Dandruff | Fine, white flakes on a dry scalp | Hydration and gentle cleansing |
| Oily Dandruff (Seborrhoeic Dermatitis) | Large, yellow, greasy flakes with redness | Antifungal shampoo & anti-inflammatory creams |
| Product-Related Dandruff | Triggered by hair sprays or shampoos | Discontinue the irritant, switch to hypoallergenic products |
| Fungal Dandruff | Caused by Malassezia yeast | Medicated antifungal shampoos (ketoconazole, ciclopirox) |
How Is Dandruff Treated by Dermatologists?
Professional dandruff treatment focuses on targeting the root cause, whether that’s fungal, inflammatory, or barrier-related, while soothing the scalp along the way.
The main treatment options include medicated shampoos, topical prescriptions, professional scalp treatments, and targeted treatment for underlying skin conditions.
Medicated Shampoos
- Contain antifungal or anti-inflammatory ingredients, such as zinc pyrithione, selenium sulfide, or ketoconazole
- Help reduce yeast growth and calm scalp irritation
Topical Prescriptions
- Corticosteroid or calcineurin inhibitors for persistent inflammation
- Hydrating scalp lotions to address flaking and dryness
Professional Scalp Treatments
- Medical scalp cleansing to remove buildup and restore balance
- Suitable for chronic, flaky scalps that haven’t responded to over-the-counter shampoos
Treating Underlying Skin Conditions
- For dandruff linked to seborrhoeic dermatitis, eczema, or psoriasis, a dermatologist may recommend a more specific therapy or a combination treatment plan

How to Prevent or Manage Dandruff?
Simple changes to your hair and scalp care routine can help reduce dandruff and prevent flare-ups. Consider the following:
- Wash hair regularly using a mild, medicated, or anti-dandruff shampoo
- Avoid harsh products, particularly those with excessive fragrance or alcohol content
- Gently exfoliate the scalp to prevent dead skin buildup
- Keep the scalp hydrated, dryness can make flaking worse
- Manage stress and maintain a balanced diet rich in zinc, omega-3, and B vitamins
When Should You See a Dermatologist?
It’s worth seeking professional help if:
Over-the-counter products haven’t worked after several weeks of consistent use
You’re experiencing redness, pain, or thick, scaly patches
The condition has spread beyond the scalp, for example to the eyebrows, nose, or chest

Frequently Asked Questions (FAQs)
Can dandruff be permanently cured?
Dandruff can be effectively controlled and kept at bay with the right treatment, though it tends to be a recurring condition for many people rather than something that’s cured once and for all. Ongoing scalp care and, where needed, periodic use of medicated shampoo usually keep symptoms well managed long term.
Is dandruff the same as a dry scalp?
Not necessarily, while a dry scalp can cause flaking similar to dandruff, dandruff itself is more often linked to yeast overgrowth or excess oil production rather than dryness alone. The two can look similar, which is why an accurate diagnosis matters before starting treatment.
What is the best dandruff treatment in Singapore?
There’s no single “best” treatment, since the right approach depends on what’s actually causing your dandruff, whether that’s fungal overgrowth, product sensitivity, or an underlying skin condition. A dermatologist assessment helps identify the cause and match you with the most effective treatment.
Is dandruff contagious?
No, dandruff itself is not contagious and cannot be spread to others through contact or shared items. It’s a condition related to your own scalp environment rather than an infection that passes between people.
Which shampoo is best for dandruff removal?
Medicated shampoos containing ingredients like ketoconazole, zinc pyrithione, or selenium sulfide are generally the most effective for fungal-related dandruff. The best choice depends on your specific type of dandruff, which is worth confirming with a dermatologist rather than guessing through trial and error.
Can dandruff cause hair loss?
Dandruff itself doesn’t typically cause hair loss, but excessive scratching from an itchy, inflamed scalp can occasionally contribute to temporary shedding or irritation-related hair thinning. Treating the underlying dandruff usually resolves this secondary effect.
Is dandruff caused by poor hygiene?
No, dandruff is not simply a result of poor hygiene, it’s typically caused by factors like yeast overgrowth, oil production, or scalp sensitivity, regardless of how often you wash your hair. In fact, washing too infrequently or with the wrong products can sometimes make symptoms worse rather than better.
How long does dandruff treatment take?
Many people notice improvement within a few weeks of starting appropriate treatment, though more persistent or severe cases can take longer to fully settle. Consistency with the recommended shampoo or treatment plan makes a significant difference to how quickly symptoms improve.
Why is my scalp so flaky even after washing?
Persistent flaking despite regular washing often points to an underlying cause like yeast overgrowth or seborrhoeic dermatitis that a standard shampoo isn’t equipped to treat. It’s worth a dermatologist assessment to identify what’s actually driving the flaking, rather than continuing to try different over-the-counter products.
When should I see a dermatologist for flaky scalp treatment?
If your symptoms haven’t improved after several weeks of over-the-counter treatment, or if you’re noticing redness, pain, or thick scaly patches, it’s a good time to see a dermatologist. Early professional input can prevent a manageable issue from becoming more chronic or uncomfortable.
