This problem is more common in men. Other things that may raise the risk are:
Problems may be mild to severe. Symptoms may also come and go over time.
The skin may have:
- Patchy scales that may look greasy or moist
- Yellow to white scales that flake off
- Itching and burning
- Small pimples on the nose, eyebrows, chest, back, arm pits, or genitals
Newborns may have a thick, yellow, crusted scalp rash known as cradle cap.
The doctor will ask about your symptoms and health history. A physical exam will be done. It will focus on the rash. This is often enough to make the diagnosis. You may need to see a doctor who treats skin problems.
There is no cure. The rash may get better on its own in children. Baby shampoo, mineral oil, and anti-fungal shampoos can help.
In others, the goal of treatment is to manage symptoms. Choices are:
- Prescription or over the counter shampoos
Prescription or over the counter creams or lotions that contain:
- Hydrocortisone or other cortisone (steroid) preparations
- Antifungal medications
- Antibiotic medication
- Pimecrolimus or tacrolimus
- Lithium salt
