What is seborrheic dermatitis and what are its symptoms?

The seborrheic dermatitis is a chronic relapsing inflammatory disease of the skin that affects about 5 % of the world’s population.
It mainly affects men between the ages of 30 and 40, who experience itching, burning, reddening of the skin and formation of dandruff and yellowish-unctuous scales on the face and scalp.

In particular, the most affected areas are the back of the ears, the inside of the ear canal, the eyebrows and the chest.

In infants seborrheic dermatitis of the scalp can appear from the first weeks of life and is defined as milk scab.

Seborrheic dermatitis: what triggers it?

Seborrheic dermatitis is a multifactorial disease that recognizes environmental factors, genetic, endocrine, dietary and can be triggered by the seasonal changes or periods of stress important.
Certainly the fungus Malassezia has a role in initiating the inflammation of DS, since these organisms are constantly isolated in the scalp of individuals with this disease.
The deficiency of vitamins B6 and B8 is another predisposing factor as well as deficits in the immune system.
From the point of view of the skin occurs a accelerated turn over of skin cells that are “flaking” faster and by an unbalanced production of sebum, both qualitatively and quantitatively.

The result is the appearance of oily “dandruff” with reddish and itchy patches, which can psychologically limit self-confidence.

Seborrheic dermatitis: how to keep it under control

The patient should be informed about the possibility of keeping under control recurrences of the disease, of reducing its frequency and intensity.

It is important to know, however, that definitive cure is not attainable for now.

It is essential for a proper lifestyle that includes a diet low in pro-inflammatory stimuli..

It is suggested in particular to avoid foods containing high amounts of saturated fat and sugar, as well as leavened products and dairy products.

A correct cleansing, is extremely important to try to keep seborrheic dermatitis under control.

It is necessary to avoid washing the hair too often because this will stimulate sebaceous secretion from the scalp, resulting in increased irritation and scaling.

Instead it may be useful to periodically perform the keratolytic peeling which remove excess scales gently without altering the hydrolipic film of the scalp.

Among the most useful natural remedies to contain DS is the gradual and controlled exposure to sunlight. In particular it has been noted that patients visibly improve during the summer season or during stays at the beach.

It is always advisable to have a correct trichological survey also to diagnose any concomitant diseases (such as androgenetic alopecia) and prepare the appropriate therapies.
