Seborrheic dermatitis is a common skin condition. It causes red, itchy, and flaky skin. You might see white or yellowish flakes on your scalp or other parts of your body.

This condition often shows up in places with many oil glands. These areas include:
- Scalp
- Face, especially around the nose and eyebrows

These include:

In most cases, no test is needed. But if the skin looks very different, they might take a small skin sample to check.
