Eczema on the scalp is a common skin condition that can cause discomfort, irritation, and noticeable changes to hair and skin. Unlike typical eczema that affects the hands, arms, or face, scalp eczema can be particularly challenging to manage because of hair growth and frequent washing routines. People with scalp eczema often experience itching, redness, flaking, and sometimes oozing or crusting, which can impact daily life and self-confidence. Understanding the causes, symptoms, and treatment options is essential for managing this condition effectively.
What Is Scalp Eczema?
Scalp eczema, also referred to as seborrheic dermatitis when occurring on the scalp, is an inflammatory skin condition. It can appear as patches of red, itchy, and scaly skin, often accompanied by dandruff-like flakes. This condition is not contagious but can be persistent, with periods of flare-ups and remissions. Scalp eczema can affect people of all ages, from infants to adults, and is sometimes seen alongside eczema in other areas of the body.

- Genetic predispositionIndividuals with a family history of eczema or other skin conditions are more likely to develop scalp eczema.

- Fungal involvementA yeast calledMalasseziacommonly grows on the scalp and may trigger inflammatory responses in sensitive individuals.
- Environmental factorsChanges in weather, humidity, and exposure to irritants like harsh shampoos can exacerbate scalp eczema.
- Stress and lifestyleEmotional stress, diet, and overall health may influence the severity of symptoms.
