Seborrheic Dermatitis: A Comprehensive Guide

Seborrheic dermatitis is a common chronic inflammatory skin condition that primarily affects areas with a high concentration of sebaceous glands, such as the scalp, face, and upper body. It’s characterized by flaky skin, itching, and redness.

Symptoms

Common symptoms of seborrheic dermatitis include:

• Flaky, scaly skin (dandruff when on the scalp)
• Redness and inflammation
• Itching and burning sensation
• Greasy, oily patches
• Yellow or white scales on top of reddish skin
• In severe cases, crusting and oozing

Causes

While the exact cause is unknown, several factors are believed to contribute:

1. Malassezia yeast: An overgrowth of this naturally occurring skin fungus may trigger inflammation.
2. Sebum production: Overactive oil glands can create an environment conducive to yeast growth.
3. Genetic predisposition: Some individuals may be more susceptible to developing the condition.
4. Immune system: An abnormal immune response may play a role.
5. Hormonal changes: Fluctuations in hormones can affect sebum production.

Certain conditions and factors can increase the risk of developing seborrheic dermatitis:

• Neurological conditions (e.g., Parkinson’s disease)
