Causes of balding (alopecia)

Baldness or alopecia is a process of full hair loss or significant thinning of the head hair. There are several types of alopecia - focal, diffuse, androgenic, androgenetic, symptomatic, total, universal and cicatrical. Androgenetic alopecia, or the so-called "male" alopecia, is the most extended form of alopecia. Researches show that 30-35% of the world's male population aged 25 to 55 years exposed to the androgenetic alopecia. This problem does not bypass the women too, although much rarer.

Due to the medicine development, the causes of androgenetic alopecia are clearly defined to nowadays. The direct cause of hair loss is the damaging effect of male hormones androgens on the hair follicles located in the frontal and parietal regions. Under the influence of hormonal activity the bulb, which has receptors, sensitive to the hormone molecules, gradually loses the ability to produce healthy hair and eventually die, causing irreversible hair loss.

Despite the fact that hormonal activity is common to all men, only a third of them, as mentioned above, suffers from balding. This is because the second key factor in the balding development is genetic information obtained by each person from his parents. It was established that in 70-72% of cases the balding gene is inherited by a man through the maternal line: his mother transmits it from her father to her son. In other cases, the balding gene is inherited from the father. Very rarely, a balding man with the androgenetic alopecia is the first in his genus.

Thus, the hair loss cause is a symbiotic effect of two factors: heredity and hormonal activity. At the same time a corolla of hair always remains on the head - in the occipital and temporal areas. The essence of this phenomenon lies in the fact that hair follicles in these areas do not have receptors to androgens, and the hairs in these areas genetically immune to falling out.

Explanation of the hair loss causes allows to find the ways to solve this problem. There are two solutions of androgenetic alopecia in theory: changing the genetic code and the suppression of hormonal activity. However, it is clear that attempts to influence on these two factors can lead to unpredictable and possibly adverse consequences. The science cannot change the genetic code yet, and intervening in the hormonal system can cause serious illnesses.

Taking into account the irreversibility of the hair follicles death in the case of androgenetic alopecia, attempts of hair restoration by conservative methods (shampoos, creams, ointments, etc.) would not be effective.

Thus, it is obvious that an effective solution of this problem is not to fight with the balding process, to deal with its consequences. In other words, the the hairline should be recreated in the bare skin areas. Where to take hairs? It is possible to implant the artificial hair (microfibre). But there are some risks. For example, in the U.S. this procedure is prohibited. Thus, the solution of the androgenetic alopecia problem is one – it is the redistribution of genetically "insured" hairs on the bare skin areas, or, as is usually called, own hair transplantation.
