Seborrhoeic Dermatitis Causes: Common Triggers & Risk Factors

Seborrhoeic Dermatitis is a chronic inflammatory skin condition that causes scaly, oily, dandruff-like flakes on the scalp, face, and other areas rich in sebaceous (oil-producing) glands.

While the exact cause is unknown, research suggests that excess oil production, immune response, yeast overgrowth, and genetics contribute to its development. Identifying and managing the underlying triggers can help reduce flare-ups and symptoms.

Primary Causes of Seborrhoeic Dermatitis

1. Malassezia Yeast Overgrowth – The Key Factor

• Seborrhoeic Dermatitis is linked to an overgrowth of Malassezia yeast, a naturally occurring fungus on the skin.
• In people with seborrhoeic dermatitis, the immune system reacts abnormally to this yeast, triggering inflammation, redness, and flaking.

2. Excess Sebum Production and Skin Oil Imbalance

• Overactive sebaceous glands lead to excess oil (sebum) production, creating an environment where Malassezia yeast thrives.
• Increased oiliness can make the skin prone to irritation and scaling.

3. Immune System Response to Yeast Overgrowth

• The immune system mistakenly attacks the Malassezia yeast, causing chronic inflammation and flaking.
• This response varies among individuals, making some people more susceptible to flare-ups.

4. Hormonal Changes and Their Role in Seborrhoeic Dermatitis

• Hormonal fluctuations, especially in puberty, pregnancy, and menopause, can trigger seborrhoeic dermatitis.
• Higher testosterone levels increase sebum production, leading to scalp irritation and flaking.

Risk Factors That Increase the Likelihood of Seborrhoeic Dermatitis

1. Neurological Conditions and Their Link to Seborrhoeic Dermatitis

• Studies show that people with neurological disorders like Parkinson’s disease, epilepsy, and spinal cord injuries are more prone to seborrhoeic dermatitis.

2. Underlying Medical Conditions and Seborrhoeic Dermatitis

• Weakened immune systems due to conditions like HIV, hepatitis C, or chronic pancreatitis increase susceptibility.

Medications That Can Trigger Seborrhoeic Dermatitis

Certain medications can increase the risk of seborrhoeic dermatitis flare-ups:

• Antidepressants (Lithium, Buspirone)
• Antipsychotics (Haloperidol, Chlorpromazine)

Mental Health and Stress-Related Triggers

1. Depression and Anxiety

• Chronic stress and anxiety can worsen seborrhoeic dermatitis by disrupting the immune system and increasing oil production.

2. Eating Disorders Like Anorexia Nervosa

• Malnutrition and nutrient deficiencies (especially zinc and B vitamins) can trigger or worsen seborrhoeic dermatitis.
