Alopecia occurs in approximately 60% of men and evolves into a baldness in 60% of these cases (that is the 40% of male population). It is a hereditary alopecia and androgen; this means that it is linked to an inherited sensitivity of the follicles at the top of the head (receding hairline, fringe, vertex and crown) to the male hormone in blood released by the adult male testicles.
In most cases, the son will follow the steps of his father´s evolution, grandfather´s or even a paternal or maternal uncle´s one.
The total baldness leaves a crown that will be the only useful reserve to extract the transplanted grafts. It is, therefore extremely important to keep this area and not damaging it.
« DIFFUSE alopecia » is a loss of density, less frequent in men and disseminated by the entire scalp. It is caused mainly for: stress, depression, exhaustion, fatigue, lacks or certain treatments...
Notice that our protocol for extraction and « 2mm grafts implant » is the only method where no graft is wasted practically. Thus the crown reserve covers a sufficient area, in most cases, to cover large areas of baldness. However, it is necessary to be 8 cm high at the rear of the crown.
Le prélèvement par « bandelette » qui jette une partie de la « bandelette » mal découpée, ne peut pas être raisonnablement renouvelé plus de 3 fois, ce qui ne suffit que rarement pour recouvrir avec une densité suffisante une vraie calvitie.
« Strips » extraction wastes a piece of strip badly cut, and it can’t be carried out three consecutive times. This will not be enough to cover a genuine baldness with a properly hair density.
As for FUE extraction: it´s needed from 4 to 6 transplants on the same area to have enough density, although a large transplant is done.
