Abstract:
The goal of hair transplantation is to restore a natural, undetectable frame of hair to the face. From the 1960s into the late 1990s, using 10 to 25 hair, 3-4 mm grafts was the mainstay of hair transplantation, despite the fact hair naturally grows in the scalp in bundles of 1 to 4 hair follicles. The 10 to 25 hair grafts looked unnatural because they were unnatural on the scalp. Today, surgeons meticulously harvest the natural 1 to 4 hair follicular groupings from donor hair and implant them in the recipient region in men and women. This technique consistently creates natural-appearing hair. Women can benefit from transplantation as much as men.
