Blame hormones and genes
This hair loss is often genetic,caused by one of the following reasons: an excessive content of the male sex hormone DHT (dihydrotestosterone), and increased sensitivity of hair follicles to the hormone. Degidrotestoseron by acting on the bulb (follicle) hair growth stage causes contraction, so that hair enters the early lag phase, followed by the deposition step.
Often accompanied by signs of androgenic alopeciaoily seborrhea (dandruff) and acne (acne), possible excessive hair growth on the face and other body parts. In men, androgenetic alopecia usually starts from the front hairline and moves to the top. In women, there is a progressive thinning and loss of hair all over the head, and especially in the field on top of parting.
As it is known, during pubertyIt increases the body's production of androgens - male sex hormones. Do boys and girls at the same time reduced the allocation of estrogen - female hormones. At the age of 18-25 years, the body produces a lot of sebum, which has a negative effect on hair growth. During this period, most often androgenic alopecia. Hair thus become thin and soft. There are a receding hairline at the side portions of the forehead, there is an intensive hair loss at the crown.
In androgenic alopecia the leading role played by genesand sex hormones. Scientists have found that the baldness gene is passed on through the maternal line through the generation and manifests in men. I recommend to anyone who began balding, to see if they had hair the father or mother's great-grandfather fell, as well as from other relatives on the maternal line. If this fact is confirmed, then you have most likely increased content of sex hormone testosterone in the follicles. It is this hormone adversely affects the hair follicles, causing the hair stops growing.
Sometimes there is hair loss in women
In women, the picture is somewhat different: in the case of normal blood levels of androgens - noted androgenic alopecia female pattern; with a significant increase - male pattern. Furthermore, among the causes of hair loss in women, it should be noted lesions ovaries, adrenals, noticeable reduction in estrogens (female hormones) after delivery, reception of some contraceptive preparations, which contain substances that lead to increased blood levels of androgens .
External manifestations of androgenetic alopeciaquite characteristic. In men, it develops, usually close to 20 years, women - 20-30 years. There hair loss, which occurs in waves, alternating with periods of remission. Often it is combined with the increased activity of the sebaceous glands, which makes patients more likely to wash my hair, which further strengthens the hair loss. Hair gradually thins, becomes colorless. Due to the shortening of the anagen phase (hair growth phase) hair length also becomes smaller.
How to recognize
To detect this condition in men is almost alwayssimple, and only for the purpose of selection of individual treatment specifying a number of desirable diagnostic tests (mainly liver function, of the prostate). For women, even when there is a clear genetic predisposition to baldness, given the severity of the psychological component, often forming a vicious cycle and lead to persistent depression, hair thinning is always a pathology. From the women's final loss of hair makes a noticeably smaller than males, sensitivity to androgen metabolism products.
Due to the fact that the issue in recent years,study the causes and mechanism of development of this disease greatly progressed, it became possible to achieve success in the treatment of androgenic alopecia. When androgenic alopecia useful vitamin and zinc. Vitamin blocks the action of androgens. Zinc when used topically lowers the activity of the sebaceous glands. Numerous animal studies have shown zinc ability to promote hair growth. Therefore, in androgenic alopecia is necessary to apply the nutritional compositions and shampoos. In androgenic alopecia beauticians recommend the use of compounds that improve the structure and appearance of hair. Every man must be prepared to ensure that the treatment of androgenic alopecia long. It must be repeated from time to time. If all these methods do not give positive results, it is possible to apply to the clinic involved in implantation and transplantation of hair.
In this issue, the greatest impact on the condition of the hair and scalp have:
- vitamins A, E, B1, B2, B6, bioflavonoids
- trace elements magnesium (Mg), silicon (Si), sulfur (S), iron (Fe), zinc (Zn), phosphorus
