Hair loss is primarily caused by aging, a change in hormones, and a family history of baldness. As a rule, the earlier hair loss begins, the more severe the baldness will become. Burns or trauma, in which case hair replacement surgery is considered a reconstructive treatment, and may be covered by health insurance, can also cause hair loss.
Baldness is often blamed on poor circulation to the scalp, vitamin deficiencies, dandruff, and even excessive hat wearing. All of these theories have been disproved. It's also not true that hair loss can be determined by looking at your maternal grandfather, or that 40-year-old men who haven't lost their hair will never lose it.
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.
