Scalp Eczema: Causes, Symptoms & How to Soothe It

You scratch your head in a meeting and flakes land on your dark baju. You have already tried three anti-dandruff shampoos from Watsons. The itch comes back anyway, and the skin behind your ears feels raw and tight. Most people assume this is stubborn dandruff. Often it is not. It is scalp eczema, and it needs a different approach.

Scalp eczema is common and very treatable once you know what is happening up there. Here is what it is, how to tell it apart from dandruff and psoriasis, what triggers it in the Malaysian climate, and how to calm it down.

What Is Scalp Eczema?

Scalp eczema is a general term for eczema, or dermatitis, on the scalp. Two conditions sit under that umbrella, and telling them apart helps you pick the right treatment.

Seborrhoeic dermatitis

The most common form in adults. It appears where oil glands are rich: the scalp, sides of the nose, eyebrows, behind the ears and sometimes the chest. Skin turns red or pink, mildly swollen, and sheds greasy yellowish flakes rather than fine white dust.

It involves malassezia, a yeast living on almost everyone's skin. It feeds on your scalp oils and releases by-products that some immune systems react to, and inflammation follows. This is why the condition is not about being dirty. People with very clean hair get it too.

Atopic eczema on the scalp

If you already have atopic eczema elsewhere, on the inner elbows, behind the knees, on the hands or as eczema on face, it can extend onto the scalp and hairline. This version is intensely itchy, drier, and more likely to crack or weep when scratched. It often runs alongside asthma, hay fever or generally sensitive skin.

Cradle cap in babies

Infants get cradle cap in the first few months of life. It looks alarming, with thick yellow greasy scales stuck to the top of the head, but it is usually painless and clears on its own within weeks to months. Gentle washing, softening the scales with a little suitable oil before shampooing, is normally enough. Never pick the scales off. If it spreads, weeps or distresses the baby, get it checked.

Symptoms of Scalp Eczema

• Persistent itching, often worse at night or after sweating
• Yellowish greasy flakes larger than dandruff, or dry papery ones if atopic
• Red or pink patches, visible when you part the hair
• Tightness, soreness or burning
• Scale and redness spreading to the hairline, eyebrows, behind the ears or sides of the nose
• Crusting or oozing where you have scratched
• Temporary thinning in patches you scratch hard
• Flare ups that track stress, heat and weather changes

Scalp Eczema vs Dandruff vs Psoriasis

These three get confused constantly, and the wrong label means months of wrong shampoo.

The short version: dandruff flakes without much redness, scalp eczema flakes with redness and itch and travels to the face, and psoriasis makes thick silvery plaques with sharp edges. Dandruff and mild seborrhoeic dermatitis sit on one spectrum, which is why some anti-dandruff shampoos help both.

What Causes Scalp Eczema?

There is no single cause. Scalp eczema is the result of a susceptible scalp meeting a set of triggers.

• Malassezia yeast. It lives on nearly every scalp. In people prone to seborrhoeic dermatitis, the immune system reacts to its by-products and inflammation follows.
• Oil production. Overactive oil glands feed the yeast, which is why it often starts in the teens and twenties, then returns in middle age.
• Heat, humidity and sweat. Malaysia's climate is a genuine factor. Sweat mixes with oil and keeps the scalp warm and damp for hours, while moving between air-conditioned offices and outdoor heat pushes it between two extremes all day.
• Trapped heat under coverings. Motorcycle helmets, caps, hard hats and headscarves keep the scalp warm and humid. None of these cause scalp eczema, but they can worsen a flare. The fix is airing and drying, not giving up the covering.
• Harsh shampoos and styling products. Strong sulfates and heavy fragrance irritate already inflamed skin.
• Washing habits. Both extremes cause trouble. Too rarely lets oil and scale build up. Too often with a harsh product leaves the scalp raw.
• Stress and poor sleep. One of the most consistent triggers reported. Deadlines and flares travel together.
• Weather changes. Haze, monsoon humidity and long stretches in air-conditioning shift how the scalp behaves.
• Underlying health. It is more common and more stubborn in people with certain neurological conditions or a weakened immune system, one reason a persistent case is worth showing to a doctor.

How Scalp Eczema Is Treated

Treatment reduces the yeast, calms inflammation and breaks the itch and scratch cycle. Most people get there over the counter.

Medicated shampoos

This is the first line, available at Watsons, Guardian or any pharmacy. Read the active ingredient, not the marketing on the front:

• Ketoconazole. An antifungal that directly targets malassezia.
• Zinc pyrithione. Antifungal and antibacterial, in many mainstream anti-dandruff shampoos.
• Selenium sulfide. Reduces yeast and slows skin cell shedding.
• Coal tar or salicylic acid. Better when there is thick, stuck scale to lift.

How you use them matters more than which you pick. Massage into the scalp, not just the hair, and leave it on three to five minutes before rinsing. Use it two to three times a week during a flare, then drop to once a week or fortnight for maintenance. Give any shampoo two to four weeks before calling it a failure.

Prescription treatment

If shampoo is not enough, a doctor can prescribe a topical steroid as a lotion, foam or solution, which spreads through hair far better than a cream. These break a flare in short courses, not daily forever. Prescription antifungal shampoos and non-steroid options for stubborn cases exist too. Have that conversation with a professional rather than improvising.

Gentle washing on non-medicated days

Use the mildest shampoo you can tolerate: fragrance-free, no strong menthol tingle, and nothing marketed as deep clarifying while your scalp is inflamed.

A Gentle Daily Scalp Care Routine

1. Wash with lukewarm water, never hot. Hot water feels good for about ten seconds, then makes the itch worse.
2. Use your fingertips, not your nails. Nails tear inflamed skin and invite infection.
3. Rinse out sweat after workouts, football or a long ride. Even without shampoo, a lukewarm rinse and proper dry beats letting sweat sit for hours.
4. Dry properly and let your scalp breathe. Never cover a damp scalp. Air dry fully, or use cool heat, before a helmet or scarf goes on, and take the cap off at home.
5. Skip heavy fragranced products during a flare. Pomades, waxes and dry shampoo add fuel. Reintroduce them once things settle.
6. Do not scratch. Cold water, a cool room and short nails break the cycle.

Look after the rest of your skin too. If eczema-prone skin on your body is dry and itchy, a fragrance-free wash plus a barrier-supporting lotion within a few minutes of towelling off keeps things calmer. Yagishi's fragrance-free goat milk body wash (RM104) and goat milk body lotion with ceramide (RM84) do that job on the body: goat milk brings lactic acid, vitamins A, B and E and fatty acids that soften and soothe, while ceramides help rebuild the barrier and reduce moisture loss. Read more about goat milk for skin. These are body products only. Your scalp needs a shampoo made for scalps.

What to Avoid

• Scratching and picking at scale, the fastest route to bleeding and infection
• Very hot water and long hot showers
• Strong clarifying or high-sulfate shampoos during a flare
• Heavy fragranced styling products, pomades and thick oils on inflamed skin
• Covering a wet or sweaty scalp for hours
• Home remedies on broken skin: neat lemon juice, undiluted vinegar, raw garlic
• Leftover steroid cream from an old prescription, especially near the eyes
• Abandoning a medicated shampoo after four days because nothing changed

When to See a Doctor

Book an appointment if:

• You are losing hair, or seeing thinning and bald patches
• The scalp is weeping, oozing, crusting yellow or smells off, suggesting infection
• There is significant pain, swelling, warmth or fever
• Four to six weeks of consistent medicated shampoo has changed nothing
• The rash is spreading fast across the face, ears or body
• The itch is wrecking your sleep or your ability to work
• A baby's cradle cap is spreading, weeping or clearly distressing them
• You are not sure whether this is eczema, psoriasis or something else

A GP handles most cases. A dermatologist is worth the referral for stubborn, widespread or repeatedly returning cases.

Frequently Asked Questions

Is it dandruff or scalp eczema?

Small dry flakes with normal-looking skin underneath is likely dandruff. A visibly red, itchy, inflamed scalp with greasy yellow flakes that spread to your eyebrows, ears or the sides of your nose is more likely seborrhoeic dermatitis, which is scalp eczema. They sit on the same spectrum, so mild cases blur together.

Does scalp eczema cause hair loss?

Not directly, and any hair loss is usually temporary. Persistent inflammation and hard scratching damage the follicle environment, so hair can thin in the patches you attack most. Once inflammation is controlled and the scratching stops, hair generally regrows. Permanent loss is uncommon, so if hair is not coming back, get it assessed.

Is scalp eczema contagious?

No. You cannot catch it or pass it on through combs, pillows, hijabs, helmets or contact. The malassezia yeast already lives on everyone's skin. The difference is how your immune system reacts to it.

How often should I wash my hair if I have scalp eczema?

In the Malaysian climate, most people with an oily, flare-prone scalp do better washing daily or every other day with something gentle, fitting the medicated shampoo in two to three times a week. A dry, atopic scalp may prefer two to four times a week. A sweaty day means rinse regardless.

Can stress really trigger a flare?

Yes, and it is one of the most commonly reported triggers. Stress affects immune signalling and inflammation, and stressed people scratch more and sleep less. Flares often land in the same week as a deadline.

Does scalp eczema go away permanently?

Seborrhoeic dermatitis is usually long-term and relapsing rather than something you cure once. That is not bad news, because it is very controllable, and most people find a maintenance routine that keeps it quiet for long stretches.

Can I use coconut oil or hair oil on my scalp?

Be careful. Oils can soften thick scale before washing, but heavy oils left on the scalp feed the yeast and can extend a flare. Use a little, leave it briefly, then wash it out. Never apply oil to broken or weeping skin.

Can I use body wash or body lotion on my scalp?

No. Body products, including Yagishi's, are formulated for skin on the body, not for scalp and hair, and they will not treat the yeast overgrowth driving most scalp eczema. Use a proper medicated or gentle shampoo on your scalp, and see a doctor if it does not settle.

Key Takeaways

• Usually seborrhoeic dermatitis in adults, sometimes atopic eczema, and cradle cap in babies
• It means itch plus visible redness plus greasy flakes, often spreading to eyebrows, ears and the sides of the nose
• Dandruff flakes without much redness, and psoriasis makes thick silvery plaques with sharp borders
• Malassezia yeast, scalp oil, heat, sweat, harsh shampoos and stress are the main drivers, and Malaysia's climate worsens several
• Medicated shampoos with ketoconazole, zinc pyrithione or selenium sulfide are the first line, left on three to five minutes
• Lukewarm water, fingertips not nails, rinsing out sweat and letting the scalp breathe all help
• Yagishi goat milk and ceramide products are body care for eczema-prone skin on the body, not a shampoo or scalp treatment
• See a doctor for hair loss, weeping, infection, or no improvement after four to six weeks
