Hair transplant surgery is a very refined technique and, unfortunately, not all of the results are desirable. The good news is, it is completely possible to perform a hair transplant procedure in the recipient area that was the same area for a first session hair transplant procedure. For example, if a patient gets a hair transplant in the temple region and the density is not optimal (meaning the recipient area results in sparse-looking hair from poor growth or not enough grafts transplanted) – a second procedure in the same area is possible. Density is a very important aspect of the results of hair restoration – too little or not enough grafts transplanted in the donor area can make the recipient area look sparse and will make it more obvious that the patient did indeed have a hair transplant.
You can tell if the density is undesirable in the recipient area by how sparse the area is on the scalp.
The goal of the hair transplant surgery is to make the hairline and the recipient area look natural – and density is one of the crucial components of this success. With that said, it’s not optimal for a hair transplant surgeon to transplant too many grafts into one area either. This may result in poor growth as well. The number of grafts needed varies from patient to patient as some are in more advanced stages of hair loss compared to others.
During the initial consultation, goals and expectations of the patient and the procedure and the importance of being realistic are discussed with the patient. It is typical that some patients will need more than one hair transplant session to achieve the density they want – depending on the extent of the hair loss and the technique used.
If the density is not the only issue, and bad scarring or pit scarring was left behind, this can also be fixed with a second procedure. The grafts would need to be transplanted in a specific direction so they grow within the current scars to hide them with the transplanted hairs from the second session process.
