Common Scalp Conditions: Atopic Dermatitis (Scalp Eczema)

Atopic dermatitis, also known as atopic eczema, is a common inflammatory skin condition that causes dry, itchy and irritated skin. It is a chronic condition that tends to follow a pattern of flare-ups and periods of improvement. Although atopic dermatitis can affect the scalp, scalp involvement is often accompanied by eczema affecting other areas of the body.

What is Atopic Dermatitis?

Atopic dermatitis, also known as 'Scalp Eczema', is associated with a combination of genetic, immune system and environmental factors. The skin barrier can be less effective, allowing the skin to lose moisture more easily and become more susceptible to irritation and inflammation.

Scalp eczema may cause the skin to become dry, itchy, red and flaky. In some cases, repeated scratching can cause the skin to become thicker or more irritated.

Atopic dermatitis is different from seborrheic dermatitis and contact dermatitis, although the conditions can sometimes appear similar and may occur alongside one another.

What are the symptoms of Atopic Dermatitis?

Common symptoms of atopic dermatitis affecting the scalp may include:

• Persistent itching
• Dry or flaky skin
• Red or inflamed areas
• Skin sensitivity or irritation
• Soreness or a tight-feeling scalp
• Cracking or thickening of the skin in more persistent cases
• Symptoms that flare and settle over time

Atopic eczema can become more noticeable following repeated scratching or rubbing, which may further damage the skin barrier and increase irritation.

What causes Atopic Dermatitis?

There is no single cause of atopic dermatitis. It is thought to result from a combination of genetic and environmental factors that affect the skin barrier and immune response.

People with atopic dermatitis may also have a personal or family history of other atopic conditions, such as asthma or hay fever. However, atopic dermatitis can occur without a family history of these conditions.

A range of factors may trigger or worsen symptoms, including:

• Dry or cold weather
• Heat and changes in humidity
• Fragrances and irritating skincare or haircare products
• Excessive washing or harsh cleansing products
• Stress
• Certain fabrics or environmental irritants
• Skin infections

Triggers vary between individuals, and sometimes a flare can occur without an obvious cause.

How can you treat Atopic Dermatitis?

Treatment aims to reduce inflammation, relieve symptoms and support the skin barrier. Regular use of moisturising or emollient products is an important part of managing atopic dermatitis, while topical anti-inflammatory treatments may be prescribed for active flares.

For more persistent or severe eczema, a GP or dermatologist may recommend additional treatments depending on the extent and severity of the condition.

Because several scalp conditions can produce similar symptoms, including seborrheic dermatitis, psoriasis and contact dermatitis, professional assessment can be helpful when the cause of persistent scalp irritation is unclear.

If you are experiencing ongoing scalp itching, dryness, redness, flaking or irritation, professional assessment can help identify the likely cause and determine whether medical treatment or referral is appropriate.
