Yeast fungus Pityrosporum Ovale
Dandruff starts with small flakes in the scalp area of the head, which are formed by pathological acceleration of cell renewal of the skin.
Dandruff is not a dangerous disease, but carries the discomfort and social inconvenience. But most interesting is that it is caused by a fungus, but rather pityrosporum ovale.
The principle of emergence of dandruff
Human skin performs protective-barrier function. From negative influences of the external environment the first suffers from the epidermis, which consists mostly of stratum corneum and has a complex structure.
The Horny layer has a unique structure called briсk and mortar (cement and brick), the role of "bricks" made of horn cells to "cement" are the intercellular lipids.
Due to the natural process of the skin surface every day there is an involuntary rejection of squamous cells. While changing clothes and while walking around the person formed hundreds of thousands of scales.
So, in one minute around a man is to 20 thousand scales. Throughout the year, each square meter is rejected more than 100 grams of flakes.
If the damaged stratum corneum and the integrity of the skin barrier due to the actions of internal and external factors, then there is an adaptive reaction that results in the acceleration Department and increase the amount of keratinised cells.
In the normal cycle of development of cells of the basal keratinocytes from the lower layers of the epidermis reach the stratum corneum in 25 – 30 days. During this period, the keratinocytes dry and orogovenia.
In the case of a fast track process for 5-14 days, then the individual cells that do not have time to lose water, stick together and peel like a yellow-white flakes or scales, called dandruff. It is the first sign of the appearance of seborrhea.
Fungus and dandruff
In the 60-ies of the last century scientists have proved the importance of the role of yeast-like fungus called Malassezia in dandruff.
About 90% of the world's population have these mushrooms in the composition of a temporary or permanent microflora of the skin. In 1984 a group of scientists have shown that the fungus Pityrosporum ovale is the main causative agent of the process, which appears dandruff.
First on the scalp emerge good conditions for the growth of the fungus Pityrosporum ovale, it multiplies and grows, accelerating the separation is not yet fully Mature and not fully dehydrated epidermalnah cells. The cells between them are glued together, that forms scales, called dandruff.

Dandruff in its classical form, is a cluster of grey or white scales on the surface of the head. Sometimes it can turn into severe form of seborrheic dermatitis.
This form of the disease is characterized by a pronounced peeling,giperkineticeskih the appearance of plaques on the skin of the scalp.
When seborrheic dermatitis skin has a distinct red color and itchy a lot more. Required medication.

The first time dandruff may occur in the period of puberty, that's when the sebaceous glands begin to work actively.
After puberty, dandruff can be disturbed in different periods of life. There are many reasons for dandruff, but it is not contagious.
Dandruff is formed when the wrong hair care products, frequent use of hair dryer for drying hair, because of the lack of vitamins A and C, stress, the use of inappropriate line of hair care, metabolic disorders, etc also contributes to loss of hair, so that it will be useful and the material — Treatment of dandruff with the use of special equipment lasts an average of 3-6 weeks.
If the dandruff on your head is permanent and is of a recurrent nature, while the man more than 20 years, selecting therapeutic shampoo is necessary to consider the nature of dandruff.
Scales may be tightly and densely to be greasy and does not flake off from the skin surface. Dandruff also happens to be dry and easily detachable from the surface of the skin. Change is the normal state of the microbial biocenosis of the skin can be the result of a pathological process in the gastrointestinal tract.
In particular, we can distinguish dysbiosis, fermentopathy, and exacerbation of chronic diseases of the gastrointestinal tract. It is therefore important to conduct high-quality clinical and laboratory research, which will be able to determine the basic biochemical parameters. Sometimes we need to perform analysis of a feces on a dysbacteriosis.
When treating dandruff you need to use drugs that improve the processes of lipolysis.
For example, the appointment of methionine normalizes the synthesis of phospholipids from fats, and also reduces the deposition of neutral fat in the liver, enhances the synthesis of creatinine, adrenaline, and activates the action of hormones and enzymes such as vitamin B12, ascorbic and folic acid. Riboflavin has an effect on the redox process, through the participation of vitamin a in fat, protein and carbohydrate metabolism.
If the person is defective nourished, it is a factor of dandruff and seborrhea. A deficiency in omega-3 fatty acids further increases the problem. however, with this "diet" After shampooing it is best to apply not only the balm but also a tonic. Serums, tonics and lotions need to run the process of restoring balance of the skin, normalizability the sebaceous glands. Such cosmetic products prevent the formation of dandruff and create additional power for the bulbshair.

After shampooing you should not attempt to dry the hair, wiping them dry with a towel is bad for the hair and scalp. The towel should only be lightly DAB wet hair.
If you wash your hair every day, 1 time per week produced the so-called "fasting day". Head to clean the egg yolk, which is well mixed in warm water. The hair is thoroughly rinsed in running water, then rinsed with water with lemon juice or vinegar. Such a rinsing effect like balm.
