"The goal of hair transplantation in these situations is to recreate and dense up the hairline," explains Bob Leonard, DO, founder and chief surgeon of the Leonard Hair Transplantation Association in Massachusetts and Rhode Island.
People may also seek corrective hair transplantation if hair loss has occurred as a result of trauma such as an accident or burn. The surgeon may perform hair transplants in the upper lips of men who had cleft palates repaired as babies, so that they can grow a mustache. They also do a lot of corrective procedures in people who had hair transplants performed with outdated plug techniques. These less precise procedures left wide spaces around each plug as well as scarring in the donor area in the back of the head.
Corrective procedures are more challenging procedures than standard transplants. Dr. Leonard says that's why it's particularly important that people find a hair transplant surgeon who has a great deal of experience performing transplants on a variety of patients.
When transplanting in a scarred area, surgeons have to be extra cautious about how close together they place the tiny grafts of hair to ensure that the hair is properly nourished. Hair growth in or near scarring may also be slower than it is healthy tissue, but Dr. Epstein says, "transplanted grafts often attract a blood supply, and that makes subsequent transplants work better."
People having this kind of transplantation may therefore require one or two additional procedures. In most cases, surgeons say, people who are patient and have enough donor hair are very satisfied with their new look.
"In people who have had a disfiguring scar, it doesn't always take a lot to make a dramatic improvement," Dr. Epstein says. "For them, a hair transplant offers a huge change in what they see in the mirror."
