- Face: eyebrows, nasolabial folds, eyelids
- Chest: central chest and upper back
- Skin folds
- Seborrhoeic dermatitis affects 4% of the population. The flaking can be a cause of a great deal of social embarrassment.
Seborrhoeic dermatitis can start at any time after puberty and is slightly more common in men. Babies can also get a short lived type of seborrhoeic dermatitis on the scalp (cradle cap) and nappy area, which usually clears after a few months. It is not hereditary.
Seborrhoeic dermatitis signs and symptoms
Seborrhoeic dermatitis can be difficult to distinguish from other kinds of dermatitis when certain areas such as the eyelid or genital area are affected or if it is very widespread. Severe scalp seborrhoeic dermatitis can resemble psoriasis.

- Scalp: Mild flaky skin, red scaly skin or a weeping rash
- Ears: Inflammation inside the ear, crusty skin and even oozing or blockage of the ear canal
- Face: red, swollen or flaky
