Causes and Treatments for Seborrheic Dermatitis 

Seborrheic dermatitis, commonly known as “เซ็บเดิร์ม” in Thai, is a common skin condition that affects the scalp, causing itching, dandruff, and flaky patches. If you’re struggling with this issue, Follizin is here to explain what seborrheic dermatitis is, how it develops, who’s at risk, and most importantly, whether it can be treated. Plus, we’ll share simple self-care tips you can follow to manage it effectively. 

What Is Seborrheic Dermatitis? 

Seborrheic dermatitis is a chronic inflammatory skin condition that typically occurs in areas rich in oil glands, such as the scalp, eyebrows, sides of the nose, and behind the ears. It causes red, irritated patches with white or yellowish flakes resembling dandruff, often accompanied by itching. While it may sound alarming, seborrheic dermatitis is not contagious or life-threatening—it just causes discomfort and can affect your confidence. 

What Causes Seborrheic Dermatitis? 

The exact cause of seborrheic dermatitis isn’t fully understood, but it’s believed to result from a combination of factors:  

• Malassezia Fungus: This yeast naturally lives on human skin, but overgrowth can lead to inflammation and irritation.  
• Immune System Response: An overactive immune response to Malassezia can trigger seborrheic dermatitis.  
• Hormonal Changes: Hormonal fluctuations during puberty, pregnancy, or periods of stress can exacerbate the condition.  
• Genetic Factors: A family history of seborrheic dermatitis increases your risk.  
• Weather Conditions: Cold, dry weather can worsen symptoms.  
• Stress: Physical or emotional stress can act as a trigger. 

Who Is at Risk for Seborrheic Dermatitis? 

While anyone can develop seborrheic dermatitis, certain groups are more prone:  

• Infants (especially in the first 3 months).  
• Adults aged 30–60.  
• Individuals with weakened immune systems.  
• People with conditions like Parkinson’s disease or obesity.  
• Those experiencing high stress levels. 

Can Seborrheic Dermatitis Be Cured? 

The good news is that seborrheic dermatitis can be managed effectively, even though it cannot be completely cured. Treatment focuses on reducing inflammation, controlling fungal growth, and relieving itching. Doctors may recommend:  

• Medicated shampoos containing ketoconazole, selenium sulfide, or zinc pyrithione.  
• Topical steroids to reduce inflammation.  
• Antifungal creams to control yeast overgrowth. 

Self-Care Tips for Managing Seborrheic Dermatitis 

Here are some easy ways to care for your scalp if you have seborrheic dermatitis:  

• Use medicated shampoo regularly as directed by your doctor or pharmacist.  
• Avoid scratching your scalp, as it can cause irritation and infection.  
• Stay away from hair styling products with alcohol, which can dry out your scalp further.  
• Reduce stress through exercise, meditation, or adequate sleep.  
• Maintain overall health by eating nutritious foods and staying hydrated. 

If you suspect you have seborrheic dermatitis, consult a dermatologist for proper diagnosis and treatment. Avoid self-medicating, as improper use of medications can lead to side effects.
