While the exact cause isn't fully understood, seborrheic dermatitis flares are often triggered by an inflammatory reaction to Malassezia yeast that naturally lives on our skin. Some people's immune systems seem to have a heightened response to this yeast, leading to symptoms.
Here are the most common triggers that can cause or worsen flare-ups:
• Stress and recovery from stressful events
• Cold, dry weather and climate changes
• Hormonal changes
• Certain medications (like lithium, interferon, and psoralen)
• Irritating ingredients in personal care products Managing flare-ups often involves good self-care practices. Regular, gentle face washing (twice daily) followed by thorough rinsing and moisturizing can help. Those with facial hair may benefit from using medicated soaps in those areas. For scalp symptoms, consulting with a healthcare provider about appropriate medicated shampoos is recommended.
