Men are affected slightly more often than women. The rash typically has a phased course, which is characterized by the alternation of mild and severe phases of the disease.
The cause of the occurrence of head gneiss is not yet fully understood. It is known that the Increased sebum production takes place and Skin fungi are involved in the development, which is why the affected skin areas become inflamed. Since most of the sebum glands are found in the hairy areas, head gneiss also occurs mainly on the head.
If one innate disposition plays a role is discussed, but has not yet been proven.
Since head gneiss occurs more frequently in males (both in infancy and in adulthood) than in females, the influence of male sex hormones (androgens) is also considered.
Because immediately after the birth the concentration of the male sex hormones (Androgens) is still increased, as these were transmitted via the mother, head gneiss occurs mainly in the first month of life. As soon as the concentration of the hormones drops, the head gneiss usually disappears again - so the assumption.

The rash is greasy and firmly adhering. As it progresses, the crusty rash turns brownish. For most of them, treatment is not necessary as the eczema heals on its own without consequences.
If the head gneiss is subsequently infected with fungi or bacteria (often from scratched areas), itching and other inflammatory symptoms such as fever, vomiting and diarrhea can occur. However, this is relatively rare.
Other parts of the body outside the head area can also be infected. In these cases, itching and inflammatory symptoms such as redness and pain are more common. Other affected parts of the body can be the axillary folds, the chest and spine area and, less often, the abdomen.
Scraping or roughly removing the scales can cause light bleeding of the skin and, as it heals, scars. Therefore, one should absolutely refrain from scraping off the scales.
