Hair replacement surgery can enhance your appearance and your self-confidence but the results won’t necessarily match your ideal. Before you decide to have surgery think carefully about your expectations and discuss them with your surgeon. It’s important to understand that all hair replacement techniques use your existing hair. The goal of surgery is to find the most efficient uses for existing hair. Hair replacement candidates must have healthy hair growth at the back and sides of the head to serve as donor areas. Donor areas are the places on the head from which grafts and flaps are taken. Other factors such as hair color texture and waviness or curliness may also affect the cosmetic result. There are a number of techniques used in hair replacement surgery. Sometimes two or more techniques are used to achieve the best results. Transplant techniques such as punch grafts mini-grafts micro-grafts slit grafts and strip grafts are generally performed on patients who desire a more modest change in hair fullness. Flaps tissue-expansion and scalp-reduction are procedures that are usually more appropriate for patients who desire a more dramatic change.
