What Causes Seborrheic Dermatitis
Although the exact cause of seborrheic dermatitis is not fully understood, several factors contribute to its development.
- Malassezia Yeast: Malassezia is a yeast found naturally on the skin. It is believed to play a significant role in developing Seborrheic Dermatitis by triggering inflammation in some individuals.
- Genetics: A family history of seborrheic dermatitis increases the likelihood of developing the condition.
- Immune System: A weakened immune system due to illness or medication can contribute to the onset of Seborrheic Dermatitis.
- Hormones: Hormonal fluctuations, particularly androgens, may play a role in developing Seborrheic Dermatitis.
- Environmental Factors: Cold, dry weather and stress can exacerbate symptoms of seborrheic dermatitis.
Symptoms Of Seborrheic Dermatitis
Seborrheic dermatitis typically presents with the following symptoms:
- Red, scaly patches on the skin, often with greasy, yellowish scales.
- Itching and burning sensation.
- Dandruff in the scalp, eyebrows, beard, or moustache.
- Redness and inflammation around the nose, ears, and chest.
A dermatologist diagnoses seborrheic dermatitis based on the appearance of the skin and its location. Sometimes, a skin biopsy may be performed to rule out other skin conditions, such as psoriasis or eczema.
Treatment for seborrheic dermatitis aims to manage symptoms and prevent flare-ups. Common treatment options include:
- Topical Antifungal Medications: These medications, such as ketoconazole, help control the growth of Malassezia yeast on the skin.
- Topical Corticosteroids: These medications reduce inflammation and itching but should be used cautiously due to potential side effects.
- Topical Calcineurin Inhibitors: These medications, such as tacrolimus and pimecrolimus, help reduce inflammation and itching without the side effects of corticosteroids.
- Medicated Seborrheic dermatitis Shampoos: Selenium sulphide, zinc pyrithione, and coal tar shampoos can help control dandruff and scalp symptoms.
- Lifestyle Modifications: Stress reduction, gentle skin care, and avoiding irritants can help prevent flare-ups.
While there is no surefire way to prevent seborrheic dermatitis, the following steps may help reduce the risk of flare-ups:
- Maintain a consistent skincare routine, using gentle, non-irritating products.
- Wash hair regularly with a medicated shampoo if dandruff is present.
- Manage stress through relaxation techniques, exercise, or counselling.
