Seborrhea is a skin disease, which consists in a violation of the function of the sebaceous glands, which in turn is expressed in increased secretion of sebum or its qualitative change. Seborrhea usually begins at puberty.
Most often, seborrhea occurs in the type of oily. The disease is caused by an increase in the secretion of the sebaceous glands, which is associated with an increase in the level of androgens. At the same time, the composition of sebum changes, which leads to a decrease in its sterilizing properties and the creation of favorable conditions for the development of microorganisms and skin lesions. The skin of the face, neck, chest and back takes on a gray-yellow color, becomes shiny and rough, and its porosity increases.
Hair quite quickly, not often already on the second or third day after washing, becomes greasy, shiny, takes on an untidy appearance, even sticks together into greasy strands. Dandruff from oily scales appears on the scalp, which is easily scraped off with a fingernail. Hair loss gradually increases, ending in a relatively short time (3-5 years, sometimes more) with significant baldness. Restoring hairline with all this is already incredible.
For aesthetic reasons, patients traditionally increase the frequency of washing their hair, but this does not give an effect – the hair quickly becomes greasy again. Moreover, washing more often provokes an even greater function of sebum, and, as a result, the hair gets dirty even faster.
This disease is accompanied by severe itching, dandruff flakes stick together, forming gray-yellowish plaques on the hair, fall from the hair onto the shoulders, giving the clothes an untidy look.
The cause of seborrhea can also be a yeast fungus that has settled in the sebaceous gland. Itching and greasiness of the skin, dandruff can be the results of his violent life.
With this disease, the hair gradually becomes thinner, loses its luster, becomes brittle, breaks off and splits at the ends, and begins to fall out intensively. Dandruff appears on the scalp in the form of easily crumbling, dry whitish scales. The disease is not often accompanied by itching.
Attempts to eliminate such phenomena by more frequent washing of the head do not give an effect, moreover, they aggravate the condition. This is understandable, since the main symptom of dry seborrhea is dry skin. Therefore, all products that degrease the skin and hair only bring harm.
