In an hair transplant, thin strips of skin containing hair are
removed from the scalp and replaced in tiny holes (often created
with the use of lasers) in the bald or thinning area. The grafted
hair falls out after the procedure but then grows back and
should last as long as the hair from the area in which it was
taken.
Scalp reduction involves surgical removal of all or part
of the bald scalp, followed by the lifting and pulling-together
of the remaining hair-bearing skin. Occasionally scalp extenders
or tissue expanders are used.
During a skin lift or graft,
a “flap” of hair-bearing
skin is surgically created and rotated onto the bald or
thinning area. Additionally, drugs such as Minoxidil and
Finasteride may be applied to the scalp alone or in conjunction
with the above procedures to preserve existing hair and
stimulate the growth of new hair.
