About Seborrheic Dermatitis

Seborrheic Dermatitis (SD) is a common, chronic inflammatory skin condition that mainly affects areas rich in sebaceous (oil-producing) glands. While it can be bothersome and persistent, it's manageable with the right approach.

What is Seborrheic Dermatitis?

SD is often associated with the presence of Malassezia yeasts, which are naturally occurring inhabitants of the skin's surface. In people with SD, the body has an inflammatory response to the byproducts of this yeast, leading to the characteristic symptoms.

It commonly manifests as:

• Redness and inflammation on the skin.

• Greasy, yellowish scales or flakes (dandruff on the scalp).

• Itching or burning sensation.

SD most frequently appears on the:

• Scalp (known as dandruff in adults, or cradle cap in infants).

• Face (especially the eyebrows, sides of the nose, and ears).

• Chest and upper back.

Who is Affected?

SD can affect people of any age, including infants (where it usually clears up on its own). In adults, it often begins after puberty and can come and go throughout life, typically triggered by various factors.

Potential Triggers for Flare-ups

While the exact cause is a combination of genetics, yeast, and oil production, several factors can trigger or worsen symptoms:

• Stress and fatigue: High-stress levels can impact your immune response and hormone balance, leading to flare-ups.

• Seasonal changes: Symptoms often worsen in cold and dry weather and improve in summer.

• Certain medical conditions: SD is more common in people with neurological conditions (like Parkinson's disease) or compromised immune systems.

• Harsh soaps and skin care products: Alcohol-based or drying products can irritate the skin and exacerbate the condition.
