Hair loss in woman

Hair loss – physiological or pathological process of hair loss. Abnormal hair loss leads to their uniform thinning, partial or complete absence in limited areas or total baldness. The causes of hair loss can serve as a lack of vitamins and trace elements, the side effects of drugs, hormones, and infectious diseases, stress, heredity, improper hair care.

Alopecia - pathological hair loss, leading to their complete disappearance or thinning in specific areas of the head or torso. The most common type is androgenetic alopecia, diffuse or symptomatic, alopecia or alopecia, scar.

Androgenetic alopecia is a thinning hair in women leading to hair thinning in the central parting of the head with the spread on its flanks. The frequency of manifestation of androgenetic alopecia in women varies - from 20% to 90% of all cases of hair loss, due to the less visible and more difficult diagnosed manifestation of alopecia in women. The causes of androgenetic alopecia are at the gene level and are as damaging impact on Volosyan follicles active form of the male sex hormone testosterone, which is formed under the influence of the enzyme 5-alpha-reductase, located in the hair follicles. Dihydrotestosterone penetrating the cell follicles causes a degeneration of the latter and, consequently, they produce hair dystrophy. Hair remain, but they are thin, short, colorless (lanugo hair) and can no longer cover up the scalp - a bald head is formed. 10-12 years after onset of alopecia mouth follicles grow with connective tissue, and they can not even produce vellus hair.

Diffuse alopecia characterized by a strong uniform hair loss over the entire surface of the scalp as a result of a failure of the hair cycle. Since diffuse alopecia is due to irregularities in the whole organism, it is sometimes referred to as symptomatic. As the prevalence of diffuse alopecia is second only to androgenetic alopecia. Women are at it to a greater extent than the male. Allocate telogen and anagen form of diffuse alopecia. A more frequent form of telogen after provoked alopecia causes up to 80% of hair follicles go into the early phase of telogen (resting), ceasing to produce hair.

Telogen form of alopecia can cause: nerve stress, hormonal disorders, for example, as a result of thyroid disease, pregnancy, receiving hormonal contraception failure, prolonged use of antibiotics, antipsychotics, antidepressants, and a number of other drugs, surgery, acute and severe chronic infectious disease , diets lack essential elements for the body.

Anagenetic form of diffuse alopecia occurs when the exposure of the body and the hair follicles in particular, a strong and fast-acting factors, resulting in the hair follicles do not have time to "hide" in the resting phase, the hair starts to fall out once the growth phase (anagen). These factors are usually radioactive radiation, chemotherapy, severe poisoning poisons.

In most cases, after the disappearance of the causes of diffuse alopecia lost hair completely restored in 3-9 months time, because here, unlike in androgenetic alopecia, there is no loss of hair follicles. Therefore, treatment of diffuse alopecia is directed, first of all, to find and eliminate the causes that caused it. After the disappearance of the reasons for a more rapid restoration of hair using various stimulants of growth - one of the most effective tools are Rena Rosh preparates.

Alopecia (alopecia), alopecia appears as a single or multiple foci of rounded balding different sizes, ranging on the scalp, in the eyebrows, beard, eyelashes or torso. With the development of foci of disease will increase and may merge with each other, forming a lesion area of arbitrary shape. If the result of the progression of the disease on the scalp is its complete baldness, alopecia is called total. Sometimes there is a complete loss of hair on the entire body - then called the universal alopecia. According to various data displays frequency alopecia areata among all types of alopecia is from 0.5% to 2%. For alopecia areata is characterized by rapid development and often spontaneous termination of the disease with full restoration of hair. However, in about 30% of cases, the disease progresses either permanently or as a last-cycle loss of hair restoration. The causes and mechanism of alopecia areata is poorly understood. It is believed that such reasons may be a violation of the immune system, genetic predisposition, stress, poor environment, physical injury and acute diseases.

Scar alopecia: a common feature of different forms of scar alopecia is irreversible damage to the hair follicles and the appearance of their place connective (scar) tissue. In the structure of scar types of alopecia areata is 1-2%. The reason may be cicatricial alopecia infections (viral, bacterial, fungal) causing inflammatory reactions around peritrichous hair in place which result is connective tissue. If the infection is treated promptly made, the hair can be maintained. Tools Rena Rosh series Citriodora help make effective cope with inflammatory reactions and save your hair. Scar areata often occurs as a result of physical injuries - injuries, thermal or chemical burns. For the treatment of alopecia is formed, there is only one method - surgery. Or balding areas are deleted if they are not too large, or in place of these transplanted healthy follicles from areas not affected by alopecia.
