Androgenetic alopecia or baldness on man’s type — the most frequent form of loss of hair at men and makes to 95 % of all cases of baldness. Every third man suffers from it.

In what is the main reason of androgenetic alopecia?

Hypocrite and Aristotle gave the indirect answer to this question: they have noticed that eunuchs do not grow bald. Their supervision has proved to be true in the XX century, in researches of professor Hamilton. The main reason of androgenetic alopecia is constant damaging influence of molecules of man’s sexual hormones on a hair follicle. To understand the mechanism of this influence, it is necessary to familiarize with some theoretical bases.

There are three phases of life cycle of a follicle:

· In a phase of anagene hair is actively produced. The given phase lasts some years; in it there are 80-85 % of follicles.

· In a phase of katagene hair production stops. Lasts katagene about 3 months.

· In a phase of telogene hair slowly separates from a follicle and moves ahead to a skin surface. In this phase there are approximately 15 % of hair, and they are lost at washing of a head and combing. (Norm loss is to 100 hairs a day).

Influence of man’s sexual hormones.

Molecules of man’s sexual hormones (in particular, dehydro-testosterone) reduce duration of a growth phase — anagene, and prolong a rest phase — telogene. At androgenetic alopecia follicles will gradually atrophy, start to make weak hair. Eventually, this process comes to the end with a progressing and irreversible hair fall.

Why at alopecia all hair does not drop out?

The answer to this question consists in anatomic features of hair follicle. The follicles located in the field of a beard and moustaches, on a breast and feet and, the most important thing, in the field of a nape, have no especial receptors, the damaging action of molecules predisposed to perception of dehydro-testosterone. Thanks to level of hormonal activity does not influence their viability and functional activity.

Really, the majority of men have about identical level of sexual hormones and their derivative, and also active enzymes. The key factor in development of androgenetic alopecia is the heredity. If the genetic information on loss of hair is not present, negative influence of man’s sexual hormones comes to naught and baldness does not come.

It is found out that the gene of loss of hair in 73-75 % of cases is inherited on a parent line, in 20 % — on fatherly, and only 5-7 % of men are the first in a sort.

Thus, androgenetic alopecia — a consequence of symbiotic influence on hair follicles of two factors: hormonal activity and hereditary predisposition. This influence is actual only for hormonal dependent follicles (having special receptor) and has no value for anatomically protected follicles that are settling down in occipital area of a head.

This article I would like to devote to transplantation of hair.

Procedure consists in change grafts with anatomically protected from loss hair follicles on the sites of a head in full or in part deprived of hair. Graft is a microscopic slice of a skin, from 0,5 to 1 mm in diameter, containing one or several hair. The donor zone is on a nape and from above is limited by an imagined line between upper edges of auricles, and from below – a line of growth of cervical hair, also it is possible to use area of temples.

Let’s say some words about reception grafts from a donor zone.

The surgeon extremely precisely calculates the area of a strip of the skin necessary for reception of the necessary quantity of grafts. The thin strip in a donor zone is shaved, made anesthesia - it is almost painless. The special techniques that the postoperative seam was generated correctly are applied to withdrawal of a strip of a skin. The cosmetic micro seam is covered at once with the hair growing above, and outwardly is not swept up.

Use also a seamless method when grafts are turn out by means of a special tubule. On a number of the serious reasons application of the given method is limited and has strict medical indications.

The second task is formation of channels.

Channels are tiny deepening in a skin of recipient zones where will keep within prepared grafts. The necessary quantity of grafts and hair follicles in each of them is underlined in special sheet before the operation beginning. With this sheet necessarily acquaint the patient. The change zone is anaesthetized by means of a small amount of intro skin injections. Subsequently the patient does not feel any painful sensations.

In parallel with formation of channels the brigade from 9-12 skilled staff nurses prepares grafts. For this purpose use special tools and the magnifying techniques. The quantity of follicles in every graft (from 1 to 4) is strictly defined by operating surgeon. Procedure is spent at observance of absolute sterility, before implantation grafts are saved cooled in a special solution.

And the last task is an implantation of grafts.

With help of special micro tweezers channels are filled with generated grafts. Process demands the jeweler techniques, therefore is spent by operational sisters replacing each other under the control of the surgeon. Very important point is observance of an orientation of growth of hair; naturalness of the future hair dress completely depends on experience and talent of the doctor.

After implantation it is checked filling of channels by means of magnifying optics. On this stage transplantation is finished. Dot crusts remain slightly visible within 7-8 days after operation. The refined techniques of a hair transplant in good clinic excludes development of hems and infectious complications.
