Don't know much about the effectiveness of the ointments and
such available to stem and reverse hair loss, but I've heard of a
procedure, Hair Weaving, that helps to improve one's appearance
immediately. 
OK, here's some info on Hair Weaving from this website, http://www.indianchild.com/hair/hair_weaving.htm
:
''Hair weaving is the science of addition of hair to the scalp by
weaving or braiding of human hair or synthetic hair. It is also
called Hair integration or Hair Intensification. The hair is woven
to the root area of the client’s hair so that it grows naturally
with the client’s hair. The drawback of the process is that it
stresses existing hair and may cause it to fall out.
Also keeping the scalp and hair clean is a problem The American
Hair Loss Council advises that only people with plenty of healthy
hair should consider hair weaving. And even they should plan to
keep the intensified hair for only a few weeks. The procedure is
more cosmetic than surgical as it involves attaching
extensions.
However the extensions must be repositioned every five to six weeks
as the hair grows out. Some of the natural hair is woven or braided
together to act as an anchor to which tufts are sewn, woven,
knitted or glued. The anchoring needs to be tightened periodically
as natural hair grows. Vigorous washing must be avoided as it may
loosen the new hair.
A person going in for a hair weaving procedure must get a patch
test done and be clear that he is not allergic to any adhesives
used or other implants that may be used during the weaving
operation. The choice of hair, whether human or synthetic depends
on factors like the weaving technique followed and the life style
of the individual. The weaving technique called the corn row is the
oldest hair weaving technique, it has been around since the 1950s
but the result is often lumpy hair. It should be avoided if you
have fine thin lumpy hair.
Partial hair additions are increasingly becoming an option for
people with pattern hair loss. However for people undergoing
chemotherapy, partial hair addition is not recommended.
Hair weaving is seen as an option by people suffering from a wide
range of hair and scalp illnesses like alopecia totalis, alopecia
universalis, ectodermal dysplasia, bums, radiation etc.
Also a head with a healthy mop of hair is seen as an indicator of
health and is an important factor for both prospective brides and
grooms in the marriage market, in a country like India. However,
since the cost is still high, the treatment is limited to the elite
or upper class.
The chief reason why people go for hair weaving is baldness, and
baldness bow a days seems to be setting in much early sometimes as
early as 20 years due the modern life style of synthetic foods,
medicines, vitamin deficiency and hypertension. .Author ~ F.
