You should know that scar tissue has its own characteristics due to disrupted blood circulation in its top layers. This means that hair transplantation in scarring areas has somewhat lower graft survival rates compared to that at healthy skin sites. The regeneration of hair follicles depends on the local blood supply.
Practice generally shows good results of hair transplantation in the areas of scar tissue that developed after plastic surgery. The effectiveness of a single-step transplantation depends on the scar location, preservation of capillary blood flow, and the direction of hair growth.
Hair transplantation is more difficult in the areas of scars resulting from mechanical damage to the skin or occurring during the remission of cicatricial alopecia. Typically, an additional hair transplantation procedure is required.
In the areas of extensive deep burn injury, the effect of the surgery largely depends on the disturbed blood flow pattern, time and location of injury, and a number of other factors. During an individual consultation, your doctor will assess the risk of transplanted hair low survival rate and the need for an additional transplantation surgery.
