Finasteride was initially marketed to treat prostate conditions
under the name Proscar in 5mg pills. It was known to inhibit the
formation of DHT, a major contributor to both prostate cancer
and male pattern hair loss.
Subsequent research showed that a 1mg daily dose of the same
drug was sufficient to control hair loss for 83% of men after
two years of treatment. Since 1998 this version has been
marketed under the brand name Propecia and it remains the only
prescription drug approved by the FDA specifically to treat hair
loss. This approval extends only to men's hair loss because of
the dangers finasteride presents to unborn male fetuses. Women
of child bearing age should therefore consult with their
physician before considering the use of this drug.
The main purpose of Propecia is to halt hair loss and maintain
what hair coverage is left. It is therefore popular with younger
men who want to control hair loss at an early stage. Men of all
ages use it in combination with minoxidil to achieve a hair loss
strategy that both halts hair loss and encourages new growth.
Propecia works by interfering with the process of androgenetic
hair loss which usually follows this process:
1. High levels of an enzyme known as 5-alpha-reductase occur in
cells of the hair follicle.
2. This enzyme converts testosterone into DHT.
3. DHT causes miniaturization of robust terminal hairs.
4. This results in fine, soft vellus hairs that provide limited
scalp coverage.
5. The growth phase gradually shortens until these hairs are
lost permanently.
Propecia inhibits the formation of DHT and over a period of
several months reduces levels of DHT sufficiently to minimize
its effects on the hair follicle.
As with any drug, finasteride can cause side effects to a
minority of users. The FDA trials reported a 2% incidence of
varying side effects but these tended to lessen as the body
adjusted to the drug over a period of months. Although Propecia
or cheaper generic versions are easily obtained on the internet
it is strongly recommended that you seek the advice of your
doctor, at least in the first instance.
