The primary consideration for men contemplating hair-replacement surgery is the time involved. Natural-appearing hair replacement usually requires multiple surgical procedures, with long recovery intervals. A full regimen of hair transplants may last anywhere from 18 months to 2 years or more. You should be aware that incisions or transplant sites might be noticeable to others, especially in the early stages of the hair transplant process. If your work or lifestyle isn’t compatible with a long treatment period, ask your surgeon about alternatives to hair-transplant options, such as flap surgery or scalp reduction.
