Abstract

Hair loss, whether partial or complete, is a cause of significant concern to both men and women, and is viewed as unaesthetic and a visible sign of aging. Advances and refinements in hair restoration techniques have culminated in the introduction of micrograft and minigraft megasessions. This technique has become widely accepted as a simple and safe procedure that recreates natural random-pattern hairlines. The hair follicles are harvested from the posterior cervical area, where 500 to 1500 follicular units can be obtained. Implantation in the bald area is performed via punctiform incisions using the No. 11 blade. After the procedure, gauze moistened in saline solution is applied over the implanted area for 24 hours. The stitches are removed on the 7th postoperative day. The final result is visible after 8 to 12 months in men and after 12 to 14 months in women. If an additional procedure is necessary, this can be performed 1 year after the initial transplantation. The quality and strength of the implanted hair persists for an indefinite period in some patients because of 1 the following particular characteristics: high histological quality of the donor area, heredity, hormones, or aging. This article also addresses the role of platelet-rich plasma growth factors in surgical treatment of male and female pattern baldness. The results of hair transplant surgery suggest that the use of autologous platelet growth factors improves capillary density. This offers a new perspective on hair transplantation and is an important contribution to implantation surgery with follicular unit megasessions.
