Successful treatment of underlying causes is most
likely to restore hair growth, be it the completion of chemotherapy,
effective cure of a scalp fungus, or control of a systemic disease.
Two relatively new drugs--minoxidil (Rogaine) and finasteride (Proscar)--promote
hair growth in a significant minority of patients, especially those
with male pattern baldness and alopecia areata. While both drugs
have so far proved to be quite safe when used for this purpose,
minoxidil is a liquid that is applied to the scalp and finasteride
is the first and only approved treatment in a pill form.
Minoxidil was approved for over-the-counter sales
in 1996. When used continuously for long periods of time, minoxidil
produces satisfactory results in about one quarter of patients with
androgenic alopecia and as many as half the patients with alopecia
areata. There is also an over-the-counter extra-strength version of
minoxidil (5% concentration) approved for use by men only. The
treatment often results in new hair that is thinner and lighter in
color. It is important to note that new hair stops growing soon
after the use of minoxidil is discontinued.
Over the past few decades there have appeared a
multitude of hair replacement methods performed by both physicians
and non-physicians. They range from simply weaving someone else's
hair in with the remains of your own to surgically transplanting
thousands of hair follicles one at a time.
Hair transplantation is completed by taking tiny
plugs of skin, each containing one to several hairs, from the back
side of the scalp. The bald sections are then implanted with the
plugs. Research completed in 2000 looked at the new technique of
hair grafting, and found that micrografts (One to two hairs
transplanted per follicle) resulted in fewer complications and the
best results
Another surgical procedure used to treat
androgenic alopecia is scalp reduction. By stretching skin the
hairless scalp can be removed and the area of bald skin decreased by
closing the space with hair-covered scalp. Hair-bearing skin can
also be folded over an area of bald skin with a technique called a
flap. |
