Seborrheic Dermatitis Complete Guide

Fast answer

Seborrheic dermatitis is a common, recurring skin condition that can cause flaking, redness, itching and greasy or dry-looking scale, particularly on the scalp, eyebrows, sides of the nose, ears, beard and chest.

It often comes and goes. Treatment depends on where the symptoms occur and how severe they are, and may include medicated shampoos or other treatments recommended by a pharmacist, GP or dermatologist alongside a gentle skincare routine.

If your symptoms keep returning, the aim isn't simply to remove every flake. Understanding where the condition is affecting you, what may be triggering flare-ups and how to avoid unnecessary irritation can make it easier to manage.

Not sure whether seborrheic dermatitis is actually causing your symptoms? Our Sensitive Scalp Hub can help if your main problem is an itchy, flaky or uncomfortable scalp.

Where is your seborrheic dermatitis?

Seborrheic dermatitis can behave differently depending on where it appears. Start with the area that is causing you the most trouble:

• Scalp: itching, dandruff, redness or persistent scale — read our scalp seborrheic dermatitis guide.
• Face: redness, flaking or irritation around the nose, eyebrows, hairline or other facial areas — visit our facial seborrheic dermatitis guide.
• Beard: redness, itching or flakes beneath facial hair — read our seborrheic dermatitis in the beard guide.
• Other areas: seborrheic dermatitis can also affect the ears and chest. If symptoms are persistent, severe or you're unsure of the cause, seek professional advice.

If you are unsure which guide applies, continue below for a complete overview of the condition.

What is seborrheic dermatitis?

Seborrheic dermatitis is a long-term inflammatory skin condition that commonly affects areas of the body where the skin produces more oil.

Typical locations include:

• the scalp
• the eyebrows
• the sides of the nose
• the ears
• the beard area
• the hairline
• the chest

Symptoms can include:

• flaking or dandruff
• itching
• redness
• greasy-looking scale
• dry-looking flakes
• sensitive or irritated skin

Why does seborrheic dermatitis keep coming back?

This is one of the most frustrating things about the condition.

Seborrheic dermatitis is often recurrent. Symptoms may improve for a period and then return again.

Malassezia yeast naturally lives on the skin of most people. Seborrheic dermatitis is associated with the skin's inflammatory response to this yeast, together with factors including oil production and individual susceptibility.

This helps explain why the condition frequently affects oil-rich areas such as the scalp, eyebrows, sides of the nose and chest.

Individual factors can also influence how frequently symptoms return and how noticeable they become.

What can trigger a seborrheic dermatitis flare-up?

Triggers vary from person to person, but symptoms may become more noticeable during periods involving:

• stress
• illness
• cold or dry weather
• hot or humid weather
• hormonal changes
• harsh or irritating haircare products
• heavily fragranced skincare
• changes to your normal washing or skincare routine

Not everybody has the same triggers. Paying attention to when symptoms become worse may help you identify patterns that affect your own skin.

If flare-ups repeatedly settle and return, read our Seborrheic Dermatitis Flare-Ups Guide.

How is seborrheic dermatitis treated?

Treatment depends on where the condition occurs and how severe the symptoms are.

For scalp seborrheic dermatitis, treatment may involve medicated shampoos or other products recommended by a pharmacist, GP or dermatologist.

Facial or body symptoms may require a different approach because products designed for the scalp are not necessarily suitable for facial skin.

A healthcare professional may recommend treatment based on your individual symptoms, particularly if the condition is persistent, severe or difficult to control.

Alongside appropriate treatment, a gentle routine may help reduce unnecessary irritation and support everyday skin or scalp comfort.

Nicola's genuine scalp experience

Persistent itching and visible flakes can affect far more than physical comfort.

Nicola told us that her intensely itchy scalp had been driving her “up the walls”. She also felt self-conscious about visible flakes appearing on the shoulders of her uniform.

Nicola initially used Bragan Skincare Atopic Cream on her scalp and later shared her experience with us. Her feedback became part of the inspiration for developing products that were easier to use through the hair, including our Scalp Soothe leave-in product.

Her experience belongs to her and individual results vary. Bragan Skincare products do not treat or cure seborrheic dermatitis and should not replace medicated treatment or professional advice.

Seborrheic dermatitis on the scalp

The scalp is one of the areas most commonly affected by seborrheic dermatitis.

Symptoms may include:

• persistent dandruff or flaking
• itching
• red or irritated skin
• greasy or dry-looking scale

If your symptoms mainly affect your scalp, start with our Scalp Seborrheic Dermatitis Guide.

Seborrheic dermatitis on the face

Facial seborrheic dermatitis commonly affects areas including:

• the sides of the nose
• the eyebrows
• the hairline
• areas around the ears

Facial skin can be particularly sensitive, so don't assume that a product intended for the scalp is appropriate for the face.

For facial symptoms, read our Facial Seborrheic Dermatitis Treatment and Gentle Care Guide.

Still flaky after moisturising? Our guide to choosing a cream for facial seborrhoeic dermatitis explains what to look for and when moisturising alone may not be enough.

How to care for seborrheic dermatitis-prone skin and scalp

A skincare routine does not replace treatment for seborrheic dermatitis, but avoiding unnecessary irritation can make everyday care easier.

Keep the routine simple

Using numerous products at the same time can make it difficult to identify what is helping and what may be irritating your skin.

Follow treatment advice

If you've been advised to use a medicated shampoo or other treatment, follow the instructions provided by your pharmacist, GP or dermatologist.

Cleanse gently

When the scalp or skin already feels irritated, aggressive scrubbing and unnecessarily harsh cleansing may make it feel even more uncomfortable.

Support dry or sensitive skin

If the skin feels dry or tight, appropriate moisturising care may help support everyday comfort.

Pay attention to triggers

Stress, weather and unsuitable hair or skincare products are among the factors some people associate with worsening symptoms.

Be consistent

Constantly changing products can make it difficult to understand how your skin or scalp is responding.

Gentle scalp care between washes

If your scalp feels dry, itchy or uncomfortable, our sensitive scalp products are designed for gentle everyday cleansing and moisturising support.

Bragan Skincare Shampoo for Sensitive Scalp is designed to gently cleanse dry, itchy and sensitive scalps.

Between washes, Bragan Skincare Scalp Soothe provides lightweight moisturising support to areas that feel dry, tight or uncomfortable.

Our Sensitive Scalp Conditioner can be used on the hair as part of the wider scalp-care routine.

These products provide supportive scalp care. They do not treat or cure seborrheic dermatitis and should not replace medicated treatment or professional medical advice.

Could it be something other than seborrheic dermatitis?

Yes.

Redness, itching and flaking are not unique to seborrheic dermatitis.

Similar-looking symptoms can occur with conditions including:

• psoriasis
• eczema
• contact dermatitis
• ordinary dandruff
• other scalp or skin conditions

This is particularly important if your symptoms do not respond as expected or you are unsure what is causing them.

If psoriasis is a possibility, visit our Psoriasis Hub. For broader dermatitis information, visit our Dermatitis Hub.

From our family snail farm in County Monaghan

Bragan Skincare began on our own family-run snail farm in County Monaghan, Ireland.

Our sensitive scalp range developed partly from conversations with customers who wanted gentler products that were easier to use through the hair.

That customer feedback continues to shape our approach: simple routines, gentle products, honest information and realistic expectations.

When should you seek medical advice?

Speak to a pharmacist, GP or dermatologist if:

• your symptoms are severe or becoming worse
• your skin becomes painful
• you notice possible signs of infection
• the condition spreads significantly
• appropriate over-the-counter treatment is not helping
• you are unsure whether the symptoms are actually seborrheic dermatitis

A healthcare professional can also help distinguish seborrheic dermatitis from other conditions that can cause similar redness, itching or flaking.

Frequently asked questions

What is seborrheic dermatitis?

Seborrheic dermatitis is a long-term inflammatory skin condition that commonly causes redness, itching, flaking and greasy or dry-looking scale. It most often affects oil-rich areas including the scalp, eyebrows, sides of the nose, ears, beard area and chest.

What causes seborrheic dermatitis?

The exact cause is not fully understood. Seborrheic dermatitis is associated with several factors, including the skin's response to Malassezia yeast, oil production, inflammation and individual susceptibility.

Why does seborrheic dermatitis keep coming back?

Seborrheic dermatitis is often a recurring condition. Symptoms can improve and then return, sometimes in response to factors such as stress, illness, weather changes or irritating hair and skincare products. Triggers vary between individuals.

Is seborrheic dermatitis the same as dandruff?

They are closely related, but they are not always identical. Dandruff mainly causes scalp flaking, while seborrheic dermatitis can also involve redness, itching, inflammation and greasy-looking scale on the scalp, face or other oil-rich areas.

How is seborrheic dermatitis treated?

Treatment depends on where the condition occurs and how severe the symptoms are. It may include medicated shampoos or other treatments recommended by a pharmacist, GP or dermatologist. Gentle cleansing and avoiding unnecessary irritation can also form part of everyday skin and scalp care.

What shampoo should I use for seborrheic dermatitis?

Medicated shampoos containing appropriate active ingredients may be recommended to help control scalp seborrheic dermatitis. A gentle shampoo can also be useful for routine cleansing when the scalp feels dry or sensitive. Read our Best Shampoo for Seborrheic Dermatitis guide for more detailed guidance.

Can seborrheic dermatitis be confused with psoriasis or eczema?

Yes. Seborrheic dermatitis, psoriasis, eczema and contact dermatitis can all cause redness, itching or flaking. If you are unsure what is causing your symptoms, seek advice from a pharmacist, GP or dermatologist rather than relying on appearance alone.

When should I seek medical advice for seborrheic dermatitis?

Seek professional advice if your symptoms are severe, painful, spreading, showing possible signs of infection or not improving with appropriate self-care or treatment. You should also seek advice if you are unsure whether seborrheic dermatitis is causing your symptoms.

Final thoughts

Seborrheic dermatitis can be frustrating because symptoms often improve and then return.

Managing it isn't simply about removing visible flakes. Understanding where the condition is affecting you, following appropriate treatment, identifying possible triggers and avoiding unnecessary irritation can all play a part in keeping symptoms under better control.

If your scalp is the main problem, continue with our Best Shampoo for Seborrheic Dermatitis guide.

If symptoms mainly affect your face, visit our Facial Seborrheic Dermatitis Treatment and Gentle Care guide.

And if you are unsure whether seborrheic dermatitis is actually responsible for your symptoms, speak to a pharmacist, GP or dermatologist.
