With the patient under local anesthesia, transplanting hair is a
grafting procedure that takes 4 to 5 hours. A strip of scalp is removed
from the back of the head, then cut up into grafts of hair.
Hundreds of
tiny slits are made in bald areas, and the hair is transplanted one or
two follicles at a time. More than one procedure is usually necessary,
and some patients have temporary swelling in the forehead or numbness in
the scalp.
It takes about 3 months for the transplanted hair to start
growing again. Each procedure costs several thousand dollars. There is
an alternative to grafting. In a transplant procedure called “the flap” a
flap of skin with hair is lifted from the scalp and rotated into the
place of the bald spot and then stitched at the hairline. The flap is
done in 4 or 5 surgical procedures over a period of a few weeks. Because
it is never completely severed from the scalp, as is the case in
grafting, the flap doesn’t lose its blood supply. As a result, the
patient heals faster and the hair keeps growing.
