HAIR SELF-PLANTING

Micro auto hair transplantation as a remedy for baldness

During a transplant of this kind, long-lived follicles (or bulbs), taken from the areas not affected by baldness, are micrografted in the thinned or bald areas. Since it is the transplant of one's own bulbs, the operation is also called hair transplantation.

Thanks to research and the discovery of new surgical techniques, hair microautotransplantation has become a surgical procedure which, despite being very sophisticated, is not demanding for the patient and can be carried out safely and successfully even in outpatient structures such as day hospital.

GENERAL INFORMATION ABOUT HAIRDRESS

Life cycle of the hair

The hair has an evolutionary cycle and does not grow indefinitely.

During a normal cycle, the hair follicle (or hair root) goes through three well-differentiated stages that alternate throughout the life of the follicle: the anagen phase, during which the hair grows, a phase that lasts approximately three years , the catagen phase, which corresponds to the hair loss and the telogen phase, during which the hair follicle maintains a state of rest that lasts about three months and the hair does not grow.

After this last phase, a new cycle begins with the anagen phase.

In this way we can lose sixty to one hundred hairs a day and at the same time start the growth of another sixty / one hundred hairs.

Overall, the life cycle of the hair goes from three to four years. The hair follicle completes some life cycles over its life. In current practice we distinguish two types of follicles: those with a short life, programmed to repeat the life cycle for about twenty-five years, and those with a long life, programmed to repeat the life cycle for about seventy / ninety years.

What is baldness?

Baldness is a natural and hereditary process that can manifest itself to varying degrees in both men and women and causes progressive and definitive hair loss. The fact that baldness is hereditary means that a man's genetic makeup determines already before birth how many and which hairs must be lost prematurely.

It also means that baldness is not avoidable and that it is only difficult to stop or at least influence its course when it has already started.

Generally baldness begins around the age of twenty / twenty-five in both men and women.

Factors such as stress, illness or malnutrition can have an effect on hair loss.

Why does baldness affect zones?

Baldness generally affects the frontal and upper portion of the head to a greater or lesser extent: the short-lived follicles degenerate progressively causing first thinning and then baldness.

In practically all cases, the hair of the lateral (parietal) and posterior (nape) regions grows throughout life: here there are almost exclusively long-lived follicles.
