    Reasons of development of seborrhea

     There is no uniform pathogenetic reason of seborrhea. It arises at a combination of genetic predisposition, violation of processes of metabolism and adverse environmental conditions. Changes of a hormonal background of natural character (pregnancy, the pubertatny and preclimacteric periods) and pathological conditions of endocrine system (diabetes, pathologies of gonads and a thyroid gland) often are followed by the seborrhea phenomena.

    Pityrosporum ovale – a drozhzhepodobny fungus which is found in 90% of the population is recognized as the main pathogenetic component in development of seborrhea today. Normal head skin microflora for 30-40% consists of mushrooms of the sort P. Ovale. However under the influence of adverse factors its quantity increases, at seborrhea it makes up to 60% of all microorganisms. Seborrhea is promoted by loss of control over growth of pitirosporovy mushrooms, it occurs at decrease in protective functions of skin. The greatest concentration of mushrooms is observed around sebaceous glands as their secret is used for growth and development of colonies.

    The fact that the phenomena of seborrhea are caused by violations of work of endocrine glands is confirmed by the fact that the intensive growth of pitirosporovy mushrooms is observed at change of the chemical composition of skin fat which normal has antiseptic properties.

High predisposition to seborrhea of a hairy part of the head and smooth skin is noted at paralysis of cranial nerves, paralyzes of a trunk and at Parkinson's disease.

    Importance of immunodeficiencies in formation of chronic seborrhea is confirmed by statistical data that incidence of seborrhea among clinically healthy people of 8 cases on each 100 people of the population whereas HIV-positive people have an incidence of 36% of total number, and seborrhea is diagnosed for patients with AIDS in 80% of cases.

    The modern trikhologiya considers that irrational correction of dandruff, aggressive hairdresser's procedures, neglect as measures of personal hygiene and vice versa their excessive application can serve in development of seborrhea by risk factors.
