### Understanding Seborrheic Dermatitis in Adults Seborrheic dermatitis, also known as cradle cap in adults, is a long-term skin condition that causes redness, white or yellow scaly patches, and dandruff on the scalp. It can also affect the face, upper chest, and back. While not serious, it requires constant treatment to manage flare-ups. ### Common Symptoms - Redness - White or yellow scaly patches - Dandruff - Itching ### Causes and Risk Factors The exact cause is unknown, but it is believed to be related to the overproduction of oil in the skin and hair follicles. A fungus called Malassezia may also play a role. Other risk factors include stress, cold and dry climates, and heavy alcohol use. ### Treatment Options #### Over-the-Counter (OTC) Shampoos - **Dandruff Shampoos**: Contain selenium sulfide, salicylic acid, zinc pyrithione, or coal tar. - **Antifungal Shampoos**: Contain ketoconazole, such as Nizoral. #### Home Remedies - **Tea Tree Oil**: Add 10 drops to your shampoo for antimicrobial effects. - **Shaving**: Men may find relief by shaving off their mustache or beard. #### Prescription Medications - **Antifungal Shampoos**: Higher concentration of antifungal medications like Ketozal (ketoconazole) or Loprox (ciclopirox). - **Topical Corticosteroids**: Available as a shampoo or foam to reduce inflammation. - **Nonsteroidal Medications**: Pimecrolimus (Elidel) or tacrolimus (Protopic) for prolonged cases. ### Managing Flare-Ups - Avoid scratching the affected areas to reduce the risk of infection. - Identify and avoid triggers such as stress and certain climates. ### Long-term Management Seborrheic dermatitis is a lifelong condition but can be managed with a good skincare routine and by recognizing triggers. It is not contagious, so you don't have to worry about spreading it to others.
