Itching scalp

Symptoms of seborrhoeic dermatitis

Symptoms of seborrhoeic dermatitis develop gradually and may include:

• dry or greasy diffuse scaling of the scalp. This is the most usual presentation.
• yellow-red scaling on those areas of the body that are generally affected in severe disease – along the hairline, behind the hair, on the eyebrows, on the bridge of the nose, in the creases between the nose and the lips inside the ears, over the sternum (middle of the chest), on the underarms and groin areas.

Causes of seborrhoeic dermatitis

Seborrhoeic dermatitis affects areas with high densities of large oil glands. The inflammation is caused by the body’s reaction to a yeast on the scalp and to products that break down oil produced by the oil gland.

Various underlying conditions can cause an itchy scalp without dandruff. Examples include head lice, hives, and dermatitis. The scalp may also be sore, dry, or tender. Treatment can depend on the cause.
