In everyday life, our hair is subjected to severe tests, the most common of them - weather conditions, such as the sun, drying wind, cold air, cold. But there are other factors affecting the condition of the hair, which depend only on us.

The structure of the hair

Hair is composed of keratin tissue and involves three layers.

The first layer - the cuticle, or outer sheath of the hair. It is composed of numerous flake keratin. If they are in close contact with each other, it provides a well-groomed hair a healthy appearance, but under the influence of aggressive environmental influences, malnutrition or improper hair care Hair Care - Take care of nutrition , Flakes exfoliate and break the hair become dull, are cut.

The second layer - the cortex is. It is located directly under the cuticle and serves as a shield consisting of keratin. It provides strength and elasticity of the hair, as well as its color because it is precisely located therein pigments.

Third layer - core. This is the central part of the hair connected with its bulb. The core of the bulb takes veschetva nutrients that enter the body inside, and delivers them to the cortex and the cuticle.

Cycles of life of hair

The life of a hair is divided into three phases:

• The growth phase (anagenesis) - it lasts from two to seven years of age and affects 85% of the hair.
• The phase of involution (katagenesis), which lasts from two to three weeks - it is subject to 1% of the hair.
• Phase loss (telogenez) - lasts a few months and affects 14% of the hair.

Considered normal loss of thirty to fifty hairs a day, sometimes more.

Hair growth

Hair grows at about 1-1.5 cm per month, but growth is not the same all over the head. Despite the conventional wisdom that accelerates the growth of a haircut, this is not true, because the growth is from the roots and cut off nearly dead hair.

Is it possible to influence the growth of hair, speed it up? It is possible, and for this it is necessary to follow a few rules. First, you need to complete a balanced diet. Consume foods containing amino acids, which help the development of keratin - they are in meat and fish. Sometimes it is recommended to take a course of drugs that should accelerate the growth of hair. Additives are needed with sulfuric amino acid, enabling the production of keratin and zinc, vitamin Vitamins for everyone   B6.

In addition, we recommend regular massage the scalp, which stimulates blood circulation, helps reduce the amount of keratinized and facilitates the growth of new hair. It should be remembered, and that the growth of hair as well as hair loss is sometimes the hormonal and genetic causes.

Sebum and greasy hair

Sebum, or sebum is produced by sebaceous glands. In normal amounts, it provides shine and elasticity, protects it from moisture loss. When the sebaceous glands are working too hard, the hair look greasy and unkempt.

Secretion of fat is directly related to the number of male and female hormones - androgen, or male hormone stimulates the production, whereas women - estrogen - slows. Hormonal imbalances, which manifest in elevated levels of male hormones in the body, leads to enhanced secretion of sebum and, as a consequence, greasy hair.

The scalp and dandruff

The scalp is the same as in the body, it consists of the subcutaneous tissue, the dermis and epidermis. Last updated regularly, because of which remain on the keratinized skin surface gradually stratifying each other. If no action is taken to rid the scalp of these particles, dandruff is formed.

There are two types of dandruff. Dry easily peeled from the scalp, and is formed as a result of dry skin with a lack of sebum. Oily seborrhea Seborrhea - treatment is not complicated, but mandatory   - Layering scales at elevated oily skin. Often dandruff is caused by a fungus, sometimes it arises only because of the increased exfoliation of dead skin particles.

The main enemies of hair

• Mechanical damage. This aggressive brushing, too tight elastics, barrettes, hair who tear, improper hair, which does not allow to maintain in good condition the scalp. Try to use a comb with a wide-toothed comb to untangle the hair.
• Heat. Too frequent use of devices to high temperatures (pliers, irons, hair dryers) are always in danger of dry up hair. Before you use this or that instrument to create installation, it is recommended to put on the hair indelible means which protect it from damage.
• Chemical damage. Colorants lift the cuticle to penetrate the paint, and was able to gain a foothold in the cortex. With regular dyeing, bleaching, special care is needed - tools that allow you to retain moisture within the hair.
