Dermatological sources indicate that the scalp is one of the areas of the upper body affected by itching, and it is sometimes considered a difficult case from a diagnostic and therapeutic point of view to complicate the physiology of its pathophysiology, especially when there is no itching in other parts of the body and the absence of an apparent pathological lesion in the scalp. The head itself. The reason for this is two things:

Scalp skin has a unique synthetic structure as a result of its dense proliferation of nerve endings feeding into hair follicles, Dermal Vasculature and the skin, which makes Scalp Neurobiology complex and sensitive, and affects the psyche of a person.

Itchy scalp may occur with or without any visible skin lesion on the scalp or other parts of the body. It may be associated with the presence of a number of different diseases in other areas of the body, including skin diseases, systemic diseases in a number of body organs, neurological diseases, and mental disorders. And by reviewing, it is generally noticed that the most important causes of their occurrence are: dandruff, reaction to a hair care product, infection with some insects and microbes, in addition to other causes.

- Dandruff

It is easy to notice the presence of "dandruff" when there are small, white, greasy-looking flakes between hair folds. Originally, crusty exfoliation of the dead outer layer of the outer skin layer occurs slowly. In most people, in normal cases, the scales are in very small pieces, which are not clearly visible.

By reviewing, there are four elements in the mechanism of the emergence of the " Dandruff " problem, namely:

  1. The "rapid" rate of exfoliation of crusts in the outer, dead layer of skin. And among ordinary people, the outer layer of skin is removed once every about a month, and in those who have "The Dandruff ", the same dead outer skin layer is changed once every between two to seven days.
  2. The presence of an oily skin complexion in which the sebaceous glands secrete unusually high amounts of "sebum" secretions.
  3. Consequently, there is an increase in the amount of crusts, and the size of the scales is so large that the naked eye can see them clearly in their white color. And because there is not enough time to dry the crusts from the amounts of natural oils attached to them, the itching condition arises in the scalp.

Dermatologists at 60minutesnews recommend using a type of shampoo to wash hair daily or once every two days, until the dandruff is gone.
