What Is Seborrheic Dermatitis? Causes, Symptoms, Diagnosis, and Treatment

Seborrheic dermatitis is a chronic inflammatory skin condition that affects the scalp, face, and other parts of the body. It is a common skin condition that affects people of all ages, including infants. It is also known as seborrheic eczema, seborrheic psoriasis, and cradle cap in infants. In this article, we will discuss the causes, symptoms, diagnosis, and treatment options for seborrheic dermatitis.

Causes of Seborrheic Dermatitis

The exact causes of seborrheic dermatitis are not fully understood. However, several factors can trigger or worsen the condition, including:

1. Malassezia Fungus

Malassezia fungus is a yeast-like fungus that lives on the skin of most adults. In people with seborrheic dermatitis, this fungus may cause an inflammatory response, leading to the development of the condition.

2. Genetics

Seborrheic dermatitis tends to run in families, suggesting that there may be a genetic predisposition to the condition.

3. Hormonal Changes

Hormonal changes, such as those that occur during puberty or pregnancy, can trigger seborrheic dermatitis or make it worse.

4. Medical Conditions

Medical conditions, such as Parkinson’s disease, HIV/AIDS, and epilepsy, can increase the risk of developing seborrheic dermatitis.

5. Stress

Stress can trigger or worsen seborrheic dermatitis in some people.
