Characteristics of seborrheic dermatitis

What is seborrheic dermatitis?

Seborrheic dermatitis is an inflammation that occurs in the scalp or other areas of the body, such as the face, eyebrows, underarms or chest.

It is characterized by the appearance of white or yellow scales of oily or dry nature. Its principal manifestations are known as dandruff or seborrhea. If it occurs in infants, it is known as cradle cap (infantile or neonatal seborrheic dermatitis, crusta lactea or milk crust)

Seborrheic dermatitis is a recurrent disease, which usually appears and disappears on people who have it. However, proper care of the skin helps delay it and decreases its aggressiveness.

Causes of seborrheic dermatitis

The main cause of seborrheic dermatitis is an excess of production of fat, which is developed because of the Malessiizia fungi that cause inflammation on the skin of the scalp and other parts of the body.

There seems to be a genetic predisposition in some people to produce more sebum than normal, however, this overproduction has been linked to factors such as:

Poor diet: It is believed that many cases of seborrheic dermatitis are caused by food allergies. A diet especially deficient in Vitamin B, especially biotin. may trigger or exacerbate seborrheic dermatitis. A deficiency of inositol may produce similar results.

Chemical or physical aggression: The use of very strong body soaps, very aggressive shampoos, full of detergents, the frequent use of hair lacquers or hair dyes can be triggers. Similarly, a too hard body or hair washing or inappropriate hair brushing can encourage peeling.

Adverse environmental conditions: Extreme temperatures, both heat and cold, worsen the symptoms.

Psychological causes: stress, situations of personal distress or unpleasant emotional states often favor the appearance of seborrheic dermatitis.

Body diseases: Some diseases such as obesity, acne, diabetes or allergy to metals (especially gold allergy) have been mentioned as potential triggers of seborrheic dermatitis. There is evidence that people with certain diseases such as Parkinson’s disease or AIDS are more likely to develop it.

Hair loss: When seborrheic dermatitis occurs on the scalp, it causes dandruff or seborrhea. Both of those are two of the most important factors for baldness or hair loss.
