In mild cases, children can be treated by a pediatrician, who will refer them to a specialist if necessary.

Seborrheic dermatitis is a common chronic skin condition that affects areas saturated with sebaceous glands: head, face, torso.
Forms and complications of seborrheic dermatitis
A distinction is made between children’s and adult forms of seborrheic dermatitis.
Sometimes the disease is associated with psoriasis (seborrheic psoriasis).
The severity of the disease ranges from mild dandruff to severe erythroderma. Dandruff affects the scalp in the hair growth area.
In 70% of children, seborrheic dermatitis usually appears at 3 months of age and resolves spontaneously by 6-12 months.
In adults, seborrheic dermatitis begins in adolescence. It predominates in young and elderly individuals. Affects men more often.
Causes of the disease
The causes of the disease are not fully understood. Seborrheic dermatitis is not a disease of the sebaceous glands, although it develops in areas saturated with them.
A significant role in the development of the disease is played by yeast-like fungi of the genus Malassezia (which exist on the skin of most healthy people, but in some people can cause rashes and skin irritation), the specific composition of skin surface lipids, as well as features of the immune response to Malazessia fungi and products of their activity.
In adults, a severe course is associated with the following conditions:
Oily skin (seborrhea);
lack of sleep and stress;
history of seborrheic dermatitis and psoriasis in relatives;
Immunosuppressive conditions (organ transplants, HIV, lymphoma);
neurological or psychiatric disease.
The main cause of seborrheic dermatitis in children is increased sebum activity (rapid growth and secretion of sebum), resulting from the circulation of maternal hormones in the child’s blood during the first weeks of life. Malassezia is not a leading factor in children, unlike in adults.
Seborrheic dermatitis is manifested by redness, peeling “greasy” scales with a certain localization of foci.
In children – isolated on the scalp (in the frontal area it is called “baby bonnet” or “milk crust”), behind the ears and in the external auditory canal, on the face (in the area of the eyebrows, wings of the nose), on the back of the neck (at the edge of hair growth), in the skin friction areas (in folds), under the diaper.
Sometimes seborrheic dermatitis in children is widespread. It is a rash in the form of spots with greasy crusts, merging into more extensive areas. In some cases, accompanied by itching.
In adults, seborrheic dermatitis is present in the scalp area, on the face: the eyebrows, behind the ears, inside the auricles, on the wings of the nose and in the areas adjacent to the nose cheeks.
It may appear as separate spots with peeling, total lesions of the scalp, blepharitis lesions of the eyelids, lesions of the chest wall as individual nodules and spots with crusts on the surface, inflammation of the hair follicles on the skin of the upper half of the trunk (ostiofolliculitis).
In typical cases, seborrheic dermatitis shows exacerbations in winter and improvements in summer.
