Scalp Eczema, Scalp Psoriasis, Seborrheic Dermatitis, Contact Dermatitis – What's the Difference?
Table of Contents
This illustrates the patterns of scalp psoriasis and scalp atopic dermatitis. The left side presents scalp psoriasis, while the right side shows scalp atopic eczema. Scalp psoriasis is characterized by more distinct borders, accompanied by scaling and flaking. In contrast, with atopic dermatitis, eczema can extend to the face and ear areas. The less defined and more 'messy' borders can also be a key differentiating factor.
Psoriasis und Ekzeme am Capillitium
In cases of seborrheic dermatitis of the scalp, dandruff and scaling are characteristically observed.
Atopic Scalp Eczema
In cases of atopy, as it can appear in other areas besides the scalp, please check the skin condition of other body parts as well.
Allergic Contact Dermatitis
The pattern of allergic contact dermatitis looks slightly different.
This is a table comparing scalp psoriasis, seborrheic dermatitis of the scalp, atopic scalp eczema, and contact dermatitis of the scalp, presented alongside the photos above. I was able to find some German resources regarding scalp symptoms.

This material was also excerpted from a German resource. This shows the pattern of scalp psoriasis, which is characterized by relatively distinct borders.
Seborrheic Scalp Dermatitis
In seborrheic scalp dermatitis, yellow scales, dandruff flakes, or crusts are observed. It is difficult to consider itching a distinguishing symptom among scalp eczema, scalp psoriasis, and seborrheic scalp dermatitis.
Tinea Capitis
It is accompanied by hair loss. Since chronic scalp inflammation can be a cause of hair loss, it is important to receive appropriate treatment.
Clinical Diagnosis of Common Scalp Disorders
This study summarizes various skin symptoms commonly observed on the scalp. Representative symptoms include dandruff, seborrheic scalp dermatitis, tinea capitis, and scalp psoriasis. It will be necessary to differentiate by checking various factors such as age, Wood's lamp examination, itching, scaling, inflammation, and hair loss.
Scalp skin diseases are often quite challenging to treat, and the course of treatment can be prolonged. Furthermore, hair loss due to chronic inflammation can cause significant stress for patients, making it essential to ensure consistent and appropriate treatment.
