There are several causes or diseases that cause hair loss on the head. The most common cause is androgenic alopecia, which affects 90% of the population. It is so named because it is related to hormones and / or genes.
Depending on whether it is a man or a woman, this "disease" manifests itself differently. For women, hair loss may be diffuse, affecting almost equally all parts of the head. Sometimes the hair on the back remains strong, which causes it can be a good donor site for transplantation. In the case of male hair loss caused by androgenetic alopecia almost always respects the sides and the region of the neck (donor zone). The secret of hair transplantation is to take hair from the donor area, which is not affected by androgenic alopecia, and take it to the less populated areas (recipient site).
The hair transplant technique, used in plastic surgery , is itself little aggressive but is very laborious, because you have to cut half of 2000 grafts (follicular units) and then place.
The hair transplant technique is divided into three distinct phases: hair removal, making the incisions and placing the grafts.
Phase 1: Removing the hair (grafts from the donor area)
Depending on the technique that we use (technical FUSS or FUE), how to extract the grafts will be different.
Phase 2: Making the Incisions
Needle from 0.9 to 1 mm, depending on the size of the grafts, placed in a knife handle designed exclusively for hair transplantation I make the incisions where they shall be placed. The number of incisions may vary from 2000 to 3000 depending on the number of grafts and spread out the area to be covered.
Phase 3: Placing the grafts
With magnifying glasses and microsurgical forceps, one by one the grafts are being placed in each of the incisions.
Once hair transplantation completed, the patient leaves the hospital in a cap, as there is no bandage.
Do not confuse the number of grafts with the number of hairs grafted. Each graft has an average of 2.5 hairs. If we multiply the number of grafts placed by 2.5 hairs, have the number of hairs transplanted.
